INTRODUCTION

The 3Com Switch 2824/3Com Switch 2816 is a versatile, easy-to-use switch. It is ideal for users who want the high-speed performance of 10/100/1000 switching but do not need sophisticated management functions. The Switch is shipped ready for use. No configuration is necessary.

The Switch can be rack-mounted or free standing.

Your Switch includes:

■ One power cord ■ Rack mounting kit ■ Four standard height, self-adhesive rubber pads ■ This User Guide and warranty card

The Switch is powered from the AC mains supply.

The Switch provides high performance switched connections to 10 Mbps, 100 Mbps, and 1000 Mbps hubs, switches, servers and workstations that need a dedicated switched link. The following figure illustrates one possible configuration. Each port has a shielded RJ-45 connector on the front panel. Each port is capable of operating at 10 Mbps, 100 Mbps or 1000 Mbps. The ports can automatically determine the speed and the duplex mode of the connected equipment and provides a suitable switched connection. At 10 Mbps and at 100 Mbps, the ports can operate in half or full duplex mode. At 1000 Mbps, the ports operate in full duplex mode only.

The numbers in this diagram refer to numbered sections in the text. A 24-port unit is shown.

Front Panel

1 24 RJ-45 10/100/1000 Ports

WARNING: RJ-45 ports. These are shielded RJ-45 data sockets. They cannot be used as standard traditional telephone sockets, or to connect the unit to a traditional PBX or public telephone network. Only connect RJ-45 data connectors, network telephony systems, or network telephones to these sockets. Either shielded or unshielded data cables with shielded or unshielded jacks can be connected to these data sockets.

The Switch has 24/16 10/100/1000 Mbps auto-negotiating ports. Each port automatically negotiates with the attached device to determine the correct speed and duplex mode of operation. Once negotiated, the port will operate in one of the following modes:

■ 10BASE-T half duplex ■ 10BASE-T full duplex ■ 100BASE-TX half duplex ■ 100BASE-TX full duplex ■ 1000BASE-T full duplex

CAUTION: The Switch supports full duplex auto-negotiation. If the connected device does not support auto-negotiation, the Switch will operate in half duplex mode, and therefore can only operate at 10 Mbps or 100 Mbps. In such a configuration, you may notice some degradation of network performance. 3Com recommends that you use devices that are capable of auto-negotiation (and that you ensure that auto-negotiation is enabled, if it is a configurable option).

All ports auto-sense an MDI/MDIX connection so each port can be connected to a device with a normal 'straight through' TP (twisted pair) cable or a 'cross-over' TP cable. Any port can therefore be used to connect to either another switch port, server, or workstation without additional configuration.

Traffic Prioritization

The Switch offers priority queuing, which means all packets that are received are examined to see if they have been priority encoded. When a packet is received, the Switch will read the priority level and determine the appropriate channel to forward the packet based on the priority level. This feature can be useful, for example, during excessive loads when one type of traffic may require priority over another. The Switch is configured to comply with 802.1p, VLAN tagged frames.

Traffic prioritization ensures that high priority data is forwarded through the Switch without being delayed by lower priority data. It differentiates traffic into classes and prioritizes those classes automatically. Traffic prioritization uses the multiple traffic queues that are present in the hardware of the Switch to ensure that high priority traffic is forwarded on a different queue from lower priority traffic, and is given preference over that traffic. This ensures that time-sensitive traffic gets the highest level of service. The 802.1D standard specifies eight distinct levels of priority (0 to 7), each of which relates to a particular type of traffic. The priority levels and their traffic types are shown in the following table.

Priority Level Traffic Type

0 Best Effort

1 Background

2 Standard (spare)

3 Excellent Effort (business critical)

4 Controlled Load (streaming multimedia)

5 Video (Interactive media), less than 100 milliseconds latency and jitter.

6 Voice (Interactive voice), less than 10 milliseconds latency and jitter.

7 Network Control Reserved traffic

The traffic prioritization feature supported by the Switch is compatible with the relevant sections of the IEEE 802.1D standard (incorporating IEEE 802.1p).

2 Activity/Link/Speed Status LEDs

The top and third row of Status LEDs, labelled "Link/Activity," show the link and activity status of the related ports:

Status Meaning

Green: The link is operating at 1000 Mbps.

Yellow: The link is operating at 10 or 100 Mbps.

Flashing: Packets are being received or transmitted on the port.

Off: The link has not been established, either nothing is connected to the port, or there is a problem:

Check that the attached device is powered on. Check that the cable is the correct type and is not faulty. If these checks do not identify the cause of the problem, it may be that the unit or the device connected to the port is faulty. Contact your supplier for further advice.

INSTALLING THE SWITCH

Positioning the Switch

When deciding where to position the Switch ensure:

It is accessible and cables can be connected easily. Cabling is away from sources of electrical noise. These include lift shafts, microwave ovens, and air conditioning units. Electromagnetic fields can interfere with the signals on copper cabling and introduce errors, therefore slowing down your network. Water or moisture cannot enter the case of the unit. Air flow around the unit and through the vents in the side of the case is not restricted (3Com recommends that you provide a minimum of 25 mm (1 in.) clearance). The air is as free from dust as possible. Temperature operating limits are not likely to be exceeded. It is recommended that the unit is installed in a clean, air conditioned environment.

It is always a good practice to wear an anti-static wrist strap when installing network equipment, connected to a ground point. If one is not available, try to keep in contact with a grounded rack and avoid touching the unit's ports and connectors, if possible. Static discharge can cause reliability problems in your equipment.

3 Duplex Status LEDs

The second and fourth row of Status LEDs, which are colored yellow, show the duplex status of the related ports:

Status Meaning

Yellow The port is operating in full duplex mode.

Off The port is operating in half duplex mode.

1000BASE-T only operates in full duplex mode. 10BASE-T/100BASE-TX can be in half or full duplex mode.

4 Power LED

The Power LED shows the power status of the Switch:

Status Meaning

Green The unit is powered on and ready for use.

Off ■The unit is not receiving power:

■Check that the power cord is connected correctly. ■If the unit still does not operate, contact your supplier.

Rear Panel Connections

5 Power Supply

The Switch automatically adjusts to the supply voltage. Only use the power cord that is supplied with the unit.

Rack Mounting or Free Standing

This unit can be mounted in a 19-inch equipment rack using the Mounting Kit. Refer to "Mounting Kit Instructions" on page 4. It can also be free standing. Do not place objects on top of the unit or stack.

The unit is supplied with four self-adhesive rubber pads. If the unit is to be part of a free standing stack, apply the pads to each marked corner area on the underside of the unit. Place the unit on top of the lower unit, ensuring that the pads locate with the recesses of the lower unit.

Do not apply the pads if you intend to rack mount the unit.

CAUTION: If installing the Switch in a free standing stack of different sized units, the smaller units must be installed above the larger ones. Do not build a free standing stack of more than six units.

Connecting to a Network Device

Follow these guidelines to connect a device to the Switch:

■ Use Category 5 unshielded or shielded (screened) 100 Ohm TP cable (or Category 3 cable for a 10 Mbps connection). 3Com recommends using Category 5E cable for 1000BASE-T operation. ■ The maximum length of cable for each connection is 100 m (328 ft). ■ Connect one end of the cable to an RJ-45 port on the Switch, and the other end to the appropriate RJ-45 port on the connecting device.

Power Supply

Power problems can be the cause of serious failures and downtime in your network. Ensure that the power input to your system is clean and free from sags and surges to avoid unforeseen network outages. 3Com recommends that you install power conditioning, especially in areas prone to black outs, power dips and electrical storms.

Powering Up

Use the following sequence to power up the Switch:

1 Check the network connections and cables. 2 Connect the power supply cable to the appropriate power socket located on the rear panel of the unit. 3 Connect the plug to the power supply outlet socket and switch on the power supply at the socket.

When the switch is powered on, the Power LED lights green. If it does not, see reference 4 in "Features of the Switch" on page 3.

MOUNTING KIT INSTRUCTIONS

Introduction

The Switch is supplied with two mounting brackets and four screws. These are used for rack mounting the unit. When mounting the unit, you should take note of the guidelines given in "Positioning the Switch" on page 3.

Rack Mounting the Units

The Switch is 1U high and will fit a standard 19-inch rack.

CAUTION: Disconnect all cables from the unit before continuing. Remove the self-adhesive pads from the underside of the unit, if already fitted.

1. Place the unit the right way up on a hard, flat surface with the front facing towards you. 2. Locate a mounting bracket over the mounting holes on one side of the unit (refer to the figure following step 6).

3. Insert the two screws supplied in the mounting kit and fully tighten with a suitable screwdriver. 4. Repeat the two previous steps for the other side of the unit. 5. Insert the unit into the 19-inch rack and secure with suitable screws (not provided). 6. Reconnect all cables.

PROBLEM SOLVING

At frequent intervals you should visually check the Switch. Regular checks can give you an early warning of a possible failure; any problems can then be attended to when there will be least effect on users.

Check that all external cabling connections are secure and that no cables are pulled taut.

Refer to the information about LEDs given earlier in this guide to see if the problem can be identified and solved. Here are some common problems that can occur:

Activity Status LED not lit for a port that has a connection.

There is a problem with this connection. Check that:

■ The device being connected to is powered on and operating correctly. ■ The cable is connected at both ends. ■ You are using a TP cable that is not damaged. If the connection is to a workstation, that the workstation's network interface card is installed and configured correctly.

All Activity LEDs appear to be lit continually. There may be broadcast storms on the network. Remove port connections one at a time, waiting a few seconds between each port. If the LEDs go off after removing a port connection, the device that was connected to that port is introducing an excessive amount of broadcast frames to the network (some pieces of network equipment operate by sending out broadcast frames regularly). Refer to the documentation that accompanies the device for information on disabling the broadcast operation.

If the problem persists and the unit still does not operate successfully, contact your supplier with the following information before returning the unit:

■ Product number and serial number (printed on a label supplied with the unit) ■ A brief description of the fault condition
