CHAPTER 1

ABOUT THE

TIGERSTACK II 10/100/1000

Overview

SMC's TigerStack II 10/100/1000 SMC8824M and SMC8848M are intelligent multilayer switches (Layer 2, 3) with 24/48 10/100/

1000BASE-T ports, four of which are combination ports* that are shared with four SFP transceiver slots (see Figure 1-1, Ports 21-24/45-48). The rear panel provides two slots for single-port 10 Gigabit Ethernet hot-swappable expansion modules, and two stacking ports. Units can be stacked up to eight high through the built-in stacking ports that provide a 48 Gbps stack backplane.

The switches include an SNMP-based management agent embedded on the main board, which supports both in-band and out-of-band access for managing the stack.

These switches can easily enhance your network with full support for Spanning Tree Protocol, Multicast Switching, Virtual LANs, and IP routing. It brings order to poorly performing networks by segregating them into separate broadcast domains with IEEE 802.1Q compliant VLANs, empowers multimedia applications with multicast switching and CoS services, and eliminates conventional router bottlenecks.

These switches can be used to augment or completely replace slow legacy routers, off-loading local IP traffic to release valuable resources for non-IP routing or WAN access. With wire-speed performance, these switches can significantly improve the throughput between IP segments or VLANs.

Figure 1-1 Front Panels

Figure 1-2 Rear Panel

Switch Architecture

These Gigabit Ethernet switches employ a wire-speed, non-blocking switching fabric. This permits simultaneous wire-speed transport of multiple packets at low latency on all ports. The switches also feature full-duplex capability on all ports, which effectively doubles the bandwidth of each connection.

For communications between different VLANs, these switches use IP routing. For communications within the same VLAN, they use store-and-forward switching to ensure maximum data integrity. With store-and-forward switching, the entire packet must be received into a buffer and checked for validity before being forwarded. This prevents errors from being propagated throughout the network.

These switches include built-in stacking ports that enable up to eight units to be connected together through a 48 Gbps stack backplane. The switch stack can be managed from a master unit using a single IP address.

These switches also include two slots on the rear panel for slide-in single-port 10GBASE modules with XFP transceivers.

Network Management Options

These switches contain a comprehensive array of LEDs for "at-a-glance" monitoring of network and port status. They also include a management agent that allows you to configure or monitor the switch using its embedded management software, or via SNMP applications. To manage each switch, you can make a direct connection to the console port (out-of-band), or you can manage the switches through a network connection (in-band) using Telnet, the on-board web agent, or SNMP-based network management software.

For a detailed description of both switches' advanced features, refer to the Management Guide.

Description of Hardware

10/100/1000BASE-T Ports

The switches contain 24/48 RJ-45 ports that operate at 10 Mbps or 100 Mbps, half or full duplex, or at 1000 Mbps, full duplex. Because all ports on these switches support automatic MDI/MDI-X operation, you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs. (See "1000BASE-T Pin Assignments" on page B-5.)

Each of these ports support auto-negotiation, so the optimum transmission mode (half or full duplex), and data rate (10, 100, or 1000 Mbps) can be selected automatically. If a device connected to one of these ports does not support auto-negotiation, the communication mode of that port can be configured manually.

SFP Slots

The Small Form Factor Pluggable (SFP) transceiver slots are shared with four of the RJ-45 ports (ports 21-24 for the SMC8824M and ports 45-48 for the SMC8848M). In its default configuration, if an SFP transceiver (purchased separately) is installed in a slot and has a valid link on its port, the associated RJ-45 port is disabled and cannot be used. The switch can also be configured to force the use of an RJ-45 port or SFP slot, as required.

10 Gigabit Ethernet Module Slots

These switches include two slots on the rear panel for hot-swappable single-port 10GBASE modules with XFP transceivers. Refer to "Optional Media Extender Module" on page 1-8 for more information on this module and the supported 10G transceivers.

Stacking Ports

Each unit includes two stacking ports that provide a 48 Gbps high-speed serial stack backplane connection. Up to eight SMC8824M or SMC8848M switches can be connected together using optional stacking cables. Note that the 24-port and 48-port switches can be mixed in the same stack. The Stack Master button enables one switch in the stack to be selected as the Master unit for managing the entire stack.

Port and System Status LEDs

These switches include a display panel for key system and port indications that simplify installation and network troubleshooting. The LEDs, which are located on the front panel for easy viewing, are shown below and described in the following tables.

Optional Redundant Power Supply

SMC supports an optional Redundant Power Supply (RPS), that can supply power to the switch in the event the internal power supply fails.

Power Supply Sockets

There are two power sockets on the rear panel of each switch. The standard power socket is for the AC power cord. The socket labeled "RPS" is for the optional Redundant Power Supply (RPS).

Introduction to Switching

A network switch allows simultaneous transmission of multiple packets via non-crossbar switching. This means that it can partition a network more efficiently than bridges or routers. These switches have, therefore, been recognized as one of the most important building blocks for today's networking technology.

When performance bottlenecks are caused by congestion at the network access point (such as the network card for a high-volume file server), the device experiencing congestion (server, power user or hub) can be attached directly to a switched port. And, by using full-duplex mode, the bandwidth of the dedicated segment can be doubled to maximize throughput.

When networks are based on repeater (hub) technology, the distance between end stations is limited by a maximum hop count. However, a switch turns the hop count back to zero. So subdividing the network into smaller and more manageable segments, and linking them to the larger network by means of a switch, removes this limitation.

A switch can be easily configured in any Ethernet, Fast Ethernet, Gigabit Ethernet, or 10G Ethernet network to significantly boost bandwidth while using conventional cabling and network cards.

Application Examples

The TigerStack II 10/100/1000 is not only designed to segment your network, but also to provide a wide range of options in setting up network connections and linking VLANs or IP subnets. Some typical applications are described below.

Collapsed Backbone

The TigerStack II 10/100/1000 is an excellent choice for mixed Ethernet, Fast Ethernet, and Gigabit Ethernet installations where significant growth is expected in the near future. In a basic stand-alone configuration, it can provide direct full-duplex connections for up to 24/48 workstations or servers. You can easily build on this basic configuration, adding direct full-duplex connections to workstations or servers. When the time comes for further expansion, just connect to another hub or switch using one of the Gigabit Ethernet ports built into the front panel, a Gigabit Ethernet port on a plug-in SFP transceiver, or a 10G transceiver on an optional module.

In the figure below, the 48-port switch is operating as a collapsed backbone for a small LAN. It is providing dedicated 10 Mbps full-duplex connections to workstations, 100 Mbps full-duplex connections to power users, and 1 Gbps full-duplex connections to servers.

Figure 2-1 Collapsed Backbone

Network Aggregation Plan

With 24 or 48 parallel bridging ports (i.e., 24 or 48 distinct collision domains), a Gigabit switch stack can collapse a complex network down into a single efficient bridged node, increasing overall bandwidth and throughput.

In the figure below, the 10/100/1000BASE-T ports in a stack of 48-port Gigabit Ethernet switches are providing 1000 Mbps connectivity through stackable switches. In addition, the switches are also connecting several servers at 10 Gbps.

Figure 2-2 Network Aggregation Plan

Remote Connections with Fiber Cable

Fiber optic technology allows for longer cabling than any other media type. A 1000BASE-SX (MMF) link can connect to a site up to 550 meters away, a 1000BASE-LX (SMF) link up to 5km , and a 1000BASE-ZX link up to 100km . This allows a switch stack to serve as a collapsed backbone, providing direct connectivity for a widespread LAN.

A 1000BASE-SX SFP transceiver can be used for a high-speed connection between floors in the same building, and a 10GBASE-LR module can be used for high-bandwidth core connections between buildings in a campus setting. For long-haul connections, a 1000BASE-ZX SFP transceiver can be used to reach another site up to 100 kilometers away.

The figure below illustrates three TigerStack II 10/100/1000 switch stacks interconnecting multiple segments with fiber cable.

Figure 2-3 Remote Connections with Fiber Cable

Making VLAN Connections

These switches support VLANs which can be used to organize any group of network nodes into separate broadcast domains. VLANs confine broadcast traffic to the originating group, and can eliminate broadcast storms in large networks. This provides a more secure and cleaner network environment.

VLANs can be based on untagged port groups, or traffic can be explicitly tagged to identify the VLAN group to which it belongs. Untagged VLANs can be used for small networks attached to a single switch. However, tagged VLANs should be used for larger networks, and all the VLANs assigned to the inter-switch links.

These switches also support multiple spanning trees which allow VLAN groups to maintain a more stable path between all VLAN members. This can reduce the overall amount of protocol traffic crossing the network, and provide a shorter reconfiguration time if any link in the spanning tree fails.

Figure 2-4 Making VLAN Connections

Note: When connecting to a switch that does not support IEEE 802.1Q VLAN tags, use untagged ports.

Application Notes

1. Full-duplex operation only applies to point-to-point access (such as when a switch is attached to a workstation, server or another switch). When the switch is connected to a hub, both devices must operate in half-duplex mode.
2. For network applications that require routing between dissimilar network types, you can attach these switches directly to a multi-protocol router.
3. As a general rule, the length of fiber optic cable for a single switched link should not exceed:

1000BASE-SX: 550m (1805 ft) for multimode fiber
1000BASE-LX: 5 km (3.1 miles) for single-mode fiber
1000BASE-ZX: 100km (62.1 miles) for single-mode fiber
10GBASE-SR: 300m (984 ft) for multimode fiber
10GBASE-LR: 10km (6.2 miles) for single-mode fiber
10GBASE-ER: 40km (24.8 miles) for single-mode fiber

However, power budget constraints must also be considered when calculating the maximum cable length for your specific environment.

Selecting a Site

TigerStack II 10/100/1000 units can be mounted in a standard 19-inch equipment rack or on a flat surface. Be sure to follow the guidelines below when choosing a location.

• The site should:

• be at the center of all the devices you want to link and near a power outlet.

• be able to maintain its temperature within 0 to 50^ (32 to 122^ ) and its humidity within 5% to 95% , non-condensing
• provide adequate space (approximately five centimeters or two inches) on all sides for proper air flow
• be accessible for installing, cabling and maintaining the devices

• allow the status LEDs to be clearly visible

• Make sure twisted-pair cable is always routed away from power lines, fluorescent lighting fixtures and other sources of electrical interference, such as radios and transmitters.

• Make sure that the unit is connected to a separate grounded power outlet that provides 100 to 240 VAC, 50 to 60Hz , is within 2m (6.6 feet) of each device and is powered from an independent circuit breaker. As with any equipment, using a filter or surge suppressor is recommended.

Ethernet Cabling

To ensure proper operation when installing the switches into a network, make sure that the current cables are suitable for 10BASE-T,

100BASE-TX or 1000BASE-T operation. Check the following criteria against the current installation of your network:

• Cable type: Unshielded twisted pair (UTP) or shielded twisted pair (STP) cables with RJ-45 connectors; Category 3 or better for 10BASE-T, Category 5 or better for 100BASE-TX, and Category 5, 5e or 6 for 1000BASE-T.
  Protection from radio frequency interference emissions
• Electrical surge suppression
• Separation of electrical wires (switch related or other) and electromagnetic fields from data based network wiring
• Safe connections with no damaged cables, connectors or shields

• A screwdriver (Phillips or flathead, depending on the type of screws used)

Mounting

A TigerStack II 10/100/1000 unit can be mounted in a standard 19-inch equipment rack or on a desktop or shelf. Mounting instructions for each type of site follow.

Rack Mounting

Before rack mounting the switch, pay particular attention to the following factors:

• Temperature: Since the temperature within a rack assembly may be higher than the ambient room temperature, check that the rack-environment temperature is within the specified operating temperature range (see page C-2).
• Mechanical Loading: Do not place any equipment on top of a rack-mounted unit.
• Circuit Overloading: Be sure that the supply circuit to the rack assembly is not overloaded.
• Grounding: Rack-mounted equipment should be properly grounded. Particular attention should be given to supply connections other than direct connections to the mains.

To rack-mount devices:

1. Attach the brackets to the device using the screws provided in the Bracket Mounting Kit.

Figure 3-2 Attaching the Brackets

1. Mount the device in the rack, using four rack-mounting screws (not provided).

Figure 3-3 Installing the Switch in a Rack

1. If installing a single switch only, turn to "Connecting to a Power Source" at the end of this chapter.
2. If installing multiple switches, mount them in the rack, one below the other, in any order.
3. If also installing an RPS, mount it in the rack below the other devices.

Desktop or Shelf Mounting

1. Attach the four adhesive feet to the bottom of the first switch.

Figure 3-4 Attaching the Adhesive Feet

1. Set the device on a flat surface near an AC power source, making sure there are at least two inches of space on all sides for proper air flow.
2. If installing a single switch only, go to "Connecting to a Power Source" at the end of this chapter.
3. If installing multiple switches, attach four adhesive feet to each one. Place each device squarely on top of the one below, in any order.
4. If also installing an RPS, place it close to the stack.

Installing an Optional Module into the Switch

Figure 3-5 Installing an Optional Module

Note: The slide-in modules are hot-swappable, you do not need to power off the switch before installing or removing a module.

To install an optional module into the switch, do the following:

1. Remove the blank metal plate (or a previously installed module) from the appropriate slot by removing the two screws with a flat-head screwdriver.
2. Before opening the package that contains the module, touch the bag to the switch casing to discharge any potential static electricity. Also, it is recommended to use an ESD wrist strap during installation.
3. Remove the module from the anti-static shielded bag.
4. Holding the module level, guide it into the carrier rails on each side and gently push it all the way into the slot, ensuring that it firmly engages with the connector.

5. If you are sure the module is properly mated with the connector, tighten the retainer screws to secure the module in the slot.

6. The Module LED on the switch's front panel should turn green to confirm that the module is correctly installed and ready to use.

Installing an Optional SFP or XFP Transceiver into the Switch

Figure 3-6 Inserting an SFP Transceiver into a Slot

The switch support the following optional transceivers:

Table 3-1 Optional Transcievers

SFP	XFP
1000BASE-SX (SMCBGSLCX1)	10GBASE-SR (SMC10GXFP-SR)
1000BASE-LX (SMCBGLLCX1)	10GBASE-LR (SMC10GXFP-LR)
1000BASE-ZX (SMCBGZLCX1)	10GBASE-ER (SMC10GXFP-ER)

To install an SFP or XFP transceiver, do the following:

1. Consider network and cabling requirements to select an appropriate transceiver type. Refer to "Connectivity Rules" on page 4-8.

2. Insert the transceiver with the optical connector facing outward and the slot connector facing down. Note that SFP and XFP transceivers are keyed so they can only be installed in one orientation.

3. Slide the transceiver into the slot until it clicks into place.

Note: SFP and XFP transceivers are hot-swappable. The switch does not need to be powered off before installing or removing a transceiver. However, always first disconnect the network cable before removing a transceiver.

Note: SFP and XFP transceivers are not provided in the switch package.

Connecting Switches in a Stack

Figure 3-7 shows how the stack cables are connected between switches in a stack. Each stacking connection is a 48 Gbps full-duplex high-speed serial link using proprietary stacking cables. The switch supports a line- and ring-topology stacking configuration, or can be used stand alone. To ensure minimal disruption in case a unit or stacking cable fails, we recommend always use a ring-topology.

In line-topology stacking there is a single stack cable connection between each switch that carries two-way communications across the stack. In ring-topology stacking, an extra cable is connected between the top and bottom switches forming a "ring" or "closed-loop." The closed-loop cable provides a redundant path for the stack link, so if one link fails, stack communications can still be maintained. Figure 3-7 illustrates a ring-topology stacking configuration.

To connect up to eight switches in a stack, perform the following steps:

1. Plug one end of the stack cable (ordered separately) in the Down (right) port of the top unit.
2. Plug the other end of the stack cable into the Up (left) port of the next unit.

3. Repeat steps 1 and 2 for each unit in the stack. Form a simple chain starting at the Down port on the top unit and ending at the Up port on the bottom unit (stacking up to 8 units).

4. (Optional) To form a wrap-around topology, plug one end of a stack cable into the Down port on the bottom unit and the other end into the Up port on the top unit.

Figure 3-7 Making Stacking Connections

1. Select the Master unit in the stack by pressing the Master button in on only one of the switches. Only one switch in the stack can operate as the Master, all other units operate in slave mode. If more than one switch in the stack is selected as Master, or if no switches are selected, the system will select the unit with the lowest MAC address as the Master.

Stacking Topologies

All units in the stack must be connected via stacking cable. You can connect units in a simple cascade configuration, connecting Down ports to Up ports, from the top unit to the bottom unit. Using this "line" topology, if any link or unit in the stack fails, the stack is split and two separate segments are formed. The Stack Link LEDs on the units that are disconnected flash to indicate that the stack link between them is not functioning. (See Table 1-2 "System Status LEDs" on page 1-6.)

When using line topology and a stack link failure occurs, the stack reboots and a Master unit is selected within each of the two stack segments. The Master unit will be either the unit with the Master button depressed or the unit with the lowest MAC address if the Master button is not depressed on any unit. When the stack reboots and resumes operations, note that the IP address will be the same for both of the stack segments. To resolve the conflicting IP addresses, you should manually replace the failed link or unit as soon as possible. If you are using a wrap-around stack topology, a single point of failure in the stack will not cause the stack to fail. It would take two or more points of failure to break the stack apart.

If the Master unit fails or is powered off, the backup unit will take control of the stack without any loss of configuration settings. The Slave unit with the lowest MAC address is selected as the backup unit.

Connecting to a Power Source

To connect a device to a power source:

1. Insert the power cable plug directly into the socket located at the back of the device.

Figure 3-8 Power Socket

1. Plug the other end of the cable into a grounded, 3-pin, AC power source.

Note: For international use, you may need to change the AC line cord. You must use a line cord set that has been approved for the socket type in your country.

1. Check the front-panel LEDs as the device is powered on to be sure the Power LED is on. If not, check that the power cable is correctly plugged in.
2. If you have purchased a Redundant Power Supply, connect it to the switch and to an AC power source now, following the instructions included with the package.

Connecting to the Console Port

The RJ-45 serial port on the switch's front panel is used to connect to the switch for out-of-band console configuration. The on-board configuration program can be accessed from a terminal or a PC running a terminal emulation program. The pin assignments used to connect to the serial port are provided in the following table.

Figure 3-9 Serial Port (RJ-45) Pin-Out

MAKING NETWORK

CONNECTIONS

Connecting Network Devices

The TigerStack II 10/100/1000 units are designed to interconnect multiple segments (or collision domains). It can be connected to network cards in PCs and servers, as well as to hubs, switches or routers. It may also be connected to devices using optional XFP or SFP transceivers.

Twisted-Pair Devices

Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends. Use Category 5, 5e or 6 cable for 1000BASE-T connections, Category 5 or better for 100BASE-TX connections, and Category 3 or better for 10BASE-T connections.

Cabling Guidelines

The RJ-45 ports on the switch support automatic MDI/MDI-X pinout configuration, so you can use standard straight-through twisted-pair cables to connect to any other network device (PCs, servers, switches, routers, or hubs).

See Appendix B "Cables" for further information on cabling.

Caution: Do not plug a phone jack connector into an RJ-45 port. This will damage the switch. Use only twisted-pair cables with RJ-45 connectors that conform to FCC standards.

Connecting to PCs, Servers, Hubs and Switches

1. Attach one end of a twisted-pair cable segment to the device's RJ-45 connector.

Figure 4-1 Making Twisted-Pair Connections

1. If the device is a PC card and the switch is in the wiring closet, attach the other end of the cable segment to a modular wall outlet that is connected to the wiring closet. (See "Network Wiring Connections" on page 4-3.) Otherwise, attach the other end to an available port on the switch.

Make sure each twisted pair cable does not exceed 100 meters (328 ft) in length.

1. As each connection is made, the Link LED (on the switch) corresponding to each port will light green (1000 Mbps) or amber (10/100 Mbps) to indicate that the connection is valid.

Network Wiring Connections

Today, the punch-down block is an integral part of many of the newer equipment racks. It is actually part of the patch panel. Instructions for making connections in the wiring closet with this type of equipment follows.

1. Attach one end of a patch cable to an available port on the switch, and the other end to the patch panel.
2. If not already in place, attach one end of a cable segment to the back of the patch panel where the punch-down block is located, and the other end to a modular wall outlet.
3. Label the cables to simplify future troubleshooting. See "Cable Labeling and Connection Records" on page 4-11.

Figure 4-2 Wiring Closet Connections

Fiber Optic SFP Devices

An optional Gigabit SFP transceiver (1000BASE-SX, 1000BASE-LX or 1000BASE-ZX) can be used for a backbone connection between switches, or for connecting to a high-speed server.

Each single-mode fiber port requires 9/125 micron single-mode fiber optic cable with an LC connector at both ends. Each multimode fiber optic port requires 50/125 or 62.5/125 micron multimode fiber optic cabling with an LC connector at both ends.

Warning: These switches use lasers to transmit signals over fiber optic cable. The lasers are compliant with the requirements of a Class 1 Laser Product and are inherently eye safe in normal operation. However, you should never look directly at a transmit port when it is powered on.

Note: When selecting a fiber SFP device, considering safety, please make sure that it can function at a temperature that is not less than the recommended maximum operational temperature of the product. You must also use an approved Laser Class 1 SFP transceiver.

1. Remove and keep the LC port's rubber cover. When not connected to a fiber cable, the rubber cover should be replaced to protect the optics.

2. Check that the fiber terminators are clean. You can clean the cable plugs by wiping them gently with a clean tissue or cotton ball moistened with a little ethanol. Dirty fiber terminators on fiber cables will impair the quality of the light transmitted through the cable and lead to degraded performance on the port.

3. Connect one end of the cable to the LC port on the switch and the other end to the LC port on the other device. Since LC connectors are keyed, the cable can be attached in only one orientation.

Figure 4-3 Making Connections to SFP Transceivers

1. As a connection is made, check the Link LED on the switch corresponding to the port to be sure that the connection is valid.

The 1000BASE-SX, 1000BASE-LX and 1000BASE-ZX fiber optic ports operate at 1 Gbps full duplex. The maximum length for fiber optic cable operating at Gigabit speed will depend on the fiber type as listed under "1000 Mbps Gigabit Ethernet Collision Domain" on page 4-9.

10 Gbps Fiber Optic Connections

An optional 10 Gigabit transceiver (XFP) can be used for a backbone connection between switches.

Single-mode fiber ports require 9/125 micron single-mode fiber optic cable. Multimode fiber optic ports require 50/125 or 62.5/125 micron multimode fiber optic cable. Each fiber optic cable must have an LC connector attached at both ends.

Warning: These switches use lasers to transmit signals over fiber optic cable. The lasers are compliant with the requirements of a Class 1 Laser Product and are inherently eye safe in normal operation. However, you should never look directly at a transmit port when it is powered on.

Note: When selecting a fiber device, considering safety, please make sure that it can function at a temperature that is not less than the recommended maximum operational temperature of the product. You must also use an approved Laser Class 1 SFP transceiver.

1. Remove and keep the port's protective cover. When not connected to a fiber cable, the cover should be replaced to protect the optics.
2. Check that the fiber terminators are clean. You can clean the cable plugs by wiping them gently with a clean tissue or cotton ball moistened with a little ethanol. Dirty fiber terminators on fiber cables will impair the quality of the light transmitted through the cable and lead to degraded performance on the port.
3. Connect one end of the cable to the LC port on the switch and the other end to the LC port on the other device. Since LC connectors are keyed, the cable can be attached in only one orientation.

Figure 4-4 Connecting to an XFP Transceiver

1. As a connection is made, check the Link LED on the module to be sure that the connection is valid.

The 10G fiber optic ports operate at 10 Gbps full duplex. The maximum length for fiber optic cable operating at 10 Gbps will depend on the fiber type as listed under "10 Gbps Ethernet Collision Domain" on page 4-8.

Connectivity Rules

When adding hubs (repeaters) to your network, please follow the connectivity rules listed in the manuals for these products. However, note that because switches break up the path for connected devices into separate collision domains, you should not include the switch or connected cabling in your calculations for cascade length involving other devices.

1000BASE-T Cable Requirements

All Category 5 UTP cables that are used for 100BASE-TX connections should also work for 1000BASE-T, providing that all four wire pairs are connected. However, it is recommended that for all critical connections, or any new cable installations, Category 5e (enhanced Category 5) or Category 6 cable should be used. The Category 5e specification includes test parameters that are only recommendations for Category 5. Therefore, the first step in preparing existing Category 5 cabling for running 1000BASE-T is a simple test of the cable installation to be sure that it complies with the IEEE 802.3-2002 standards.

Cable Labeling and Connection Records

When planning a network installation, it is essential to label the opposing ends of cables and to record where each cable is connected. Doing so will enable you to easily locate inter-connected devices, isolate faults and change your topology without need for unnecessary time consumption.

To best manage the physical implementations of your network, follow these guidelines:

• Clearly label the opposing ends of each cable.
• Using your building's floor plans, draw a map of the location of all network-connected equipment. For each piece of equipment, identify the devices to which it is connected.
• Note the length of each cable and the maximum cable length supported by the switch ports.
• For ease of understanding, use a location-based key when assigning prefixes to your cable labeling.
• Use sequential numbers for cables that originate from the same equipment.
• Differentiate between racks by naming accordingly.
• Label each separate piece of equipment.
• Display a copy of your equipment map, including keys to all abbreviations at each equipment rack.

Power and Cooling Problems

If the power indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power cord, or internal power supply. However, if the unit powers off after running for a while, check for loose power connections, power losses or surges at the power outlet, and verify that the fans on the unit are unobstructed and running prior to shutdown. If you still cannot isolate the problem, then the internal power supply may be defective.

Installation

Verify that all system components have been properly installed. If one or more components appear to be malfunctioning (such as the power cord or network cabling), test them in an alternate environment where you are sure that all the other components are functioning properly.

In-Band Access

You can access the management agent in the switch from anywhere within the attached network using Telnet, a Web browser, or other network management software tools. However, you must first configure the switch with a valid IP address, subnet mask, and default gateway. If you have trouble establishing a link to the management agent, check to see if you have a valid network connection. Then verify that you entered the correct IP address. Also, be sure the port through which you are connecting to the switch has not been disabled. If it has not been disabled, then check the network cabling that runs between your remote location and the switch.

Caution: The management agent can accept up to four simultaneous Telnet sessions. If the maximum number of sessions already exists, an additional Telnet connection will not be able to log into the system.

Stack Troubleshooting

If a stack fails to initialize or function, first check the following items:

• Check that all stacking cables are properly connected.
• Check if any stacking cables appear damaged.
• Check that only one Stack Master button is pressed in.
• Check that all switches in the stack are powered on.

After checking all items, reboot all the switches in the stack.

Switches in the stack may be configured using a ring- or line-topology. To ensure minimal disruption in case a unit or stacking cable fails, always use a ring-topology. When using ring-topology configuration and a switch fails, or a stacking cable is disconnected, the stack continues normal operation using line-topology stacking through the remaining stack connections.

If any changes occur to a slave unit, such as unit failure or insertion of a new unit, operation of the other units in the stack are not affected. On the other hand, if the master unit fails, the unit with the lowest MAC address is elected as the new master. The stack reboots, discovers the new stack topology, assigns identifiers to each unit, and checks the software images on each unit. This process makes take up two minutes.

If you do not connect a wrap-around cable from the bottom unit back up to the top unit in the stack, the failure of a single unit will cause the stack to break into two separate stacks. In this case, a master unit will be elected for both of the stacks. However, backup information inherited from the previous master unit will cause the same IP address to be used by both master units in the two stacks. You must therefore manually reconfigure the IP address of the management interface on one of the master units.

Twisted-Pair Cable and Pin Assignments

For 10BASE-T/100BASE-TX connections, a twisted-pair cable must have two pairs of wires. For 1000BASE-T connections the twisted-pair cable must have four pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be green and the other, green with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable.

Caution: Each wire pair must be attached to the RJ-45 connectors in a specific orientation.

Caution: DO NOT plug a phone jack connector into any RJ-45 port. Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards.

Figure B-1 illustrates how the pins on the RJ-45 connector are numbered. Be sure to hold the connectors in the same orientation when attaching the wires to the pins.

Figure B-1 RJ-45 Connector Pin Numbers

10BASE-T/100BASE-TX Pin Assignments

Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45 connections: 100-ohm Category 3 or better cable for 10 Mbps connections, or 100-ohm Category 5 or better cable for 100 Mbps connections. Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet).

The RJ-45 ports on the switch base unit support automatic MDI/MDI-X operation, so you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs. In straight-through cable, pins 1, 2, 3, and 6, at one end of the cable, are connected straight through to pins 1, 2, 3, and 6 at the other end of the cable. When using any RJ-45 port on these switches, you can use either straight-through or crossover cable.

Table B-1 10/100BASE-TX MDI and MDI-X Port Pinouts

Pin	MDI Signal Name	MDI-X Signal Name
1	Transmit Data plus (TD+)	Receive Data plus (RD+)
2	Transmit Data minus (TD-)	Receive Data minus (RD-)
3	Receive Data plus (RD+)	Transmit Data plus (TD+)
6	Receive Data minus (RD-)	Transmit Data minus (TD-)
4,5,7,8	Not used	Not used

Note: The "+" and "-" signs represent the polarity of the wires that make up each wire pair.

Straight-Through Wiring

If the twisted-pair cable is to join two ports and only one of the ports has an internal crossover (MDI-X), the two pairs of wires must be

straight-through. (When auto-negotiation is enabled for any RJ-45 port on these switches, you can use either straight-through or crossover cable to connect to any device type.)

You must connect all four wire pairs as shown in the following diagram to support Gigabit Ethernet connections.

EIA/TIA 568B RJ-45 Wiring Standard 10/100BASE-TX Straight-through Cable
Figure B-2 Straight-through Wiring

Crossover Wiring

If the twisted-pair cable is to join two ports and either both ports are labeled with an "X" (indicating MDI-X) or neither port is labeled with an "X" (which indicates MDI), a crossover must be implemented in the wiring. (When auto-negotiation is enabled for any RJ-45 port on these switches, you can use either straight-through or crossover cable to connect to any device type.)

You must connect all four wire pairs as shown in the following diagram to support Gigabit Ethernet connections.

EIA/TIA 568B RJ-45 Wiring Standard 10/100BASE-TX Crossover Cable
Figure B-3 Crossover Wiring

1000BASE-T Pin Assignments

All 1000BASE-T ports support automatic MDI/MDI-X operation, so you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs.

The table below shows the 1000BASE-T MDI and MDI-X port pinouts. These ports require that all four pairs of wires be connected. Note that for 1000BASE-T operation, all four pairs of wires are used for both transmit and receive.

Use 100-ohm Category 5, 5e or 6 unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for 1000BASE-T connections. Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet).

Cable Testing for Existing Category 5 Cable

Installed Category 5 cabling must pass tests for Attenuation, Near-End Crosstalk (NEXT), and Far-End Crosstalk (FEXT). This cable testing information is specified in the ANSI/TIA/EIA-TSB-67 standard. Additionally, cables must also pass test parameters for Return Loss and Equal-Level Far-End Crosstalk (ELFEXT). These tests are specified in the ANSI/TIA/EIA-TSB-95 Bulletin, "The Additional Transmission Performance Guidelines for 100 Ohm 4-Pair Category 5 Cabling."

Note that when testing your cable installation, be sure to include all patch cables between switches and end devices.

Adjusting Existing Category 5 Cabling to Run 1000BASE-T

If your existing Category 5 installation does not meet one of the test parameters for 1000BASE-T, there are basically three measures that can be applied to try and correct the problem:

1. Replace any Category 5 patch cables with high-performance Category 5e or Category 6 cables.
2. Reduce the number of connectors used in the link.
3. Reconnect some of the connectors in the link.

Fiber Standards

The current TIA (Telecommunications Industry Association) 568-A specification on optical fiber cabling consists of one recognized cable type for horizontal subsystems and two cable types for backbone subsystems.

Horizontal 62.5/125 micron multimode (two fibers per outlet).

Backbone 62.5/125 micron multimode or single mode.

TIA 568-B will allow the use of 50/125 micron multimode optical fiber in both the horizontal and backbone in addition to the types listed above. All optical fiber components and installation practices must meet applicable building and safety codes.
