Chapter 1

Getting to Know Your Switch

This chapter describes the key features, benefits and applications of your switch.

1.1 Introduction

The ES-1124 is a multi-port switch that can be used to build high-performance switched workgroup networks. This switch is a store-and-forward device that offers low latency for high-speed networking. The switch is targeted at workgroup, department or backbone computing environments for SME (small, medium enterprise) businesses.

Figure 1-1 The ES-1124

The ES-1124 features a "store-and-forward" switching scheme. This allows the switch to auto-learn and store source address in an 8K-entry MAC address table.

All ports are auto-crossover, that is auto-MDIX ports (Media Dependent Interface Crossover), so you may use either a straight through Ethernet cable or crossover Ethernet cable for all Ethernet port connections. Auto-crossover ports automatically sense whether they need to function as crossover or straight ports, so crossover cables can connect both computers and switches/hubs.

The ES-1124 has 24 auto-crossover 10/100Base-TX RJ-45 ports and 2 auto-detect gigabit ports for higher connection speed.

1.2 Features

1.4 Ethernet Switching Technology

Ethernet Switching Technology has dramatically boosted the total bandwidth of a network, eliminated congestion problems inherent with CSMA/CD (Carrier Sense multiple access with Collision Detection) protocol, and greatly reduced unnecessary transmissions.

This revolutionized networking in a number of ways:

• By allowing two-way, simultaneous transmissions over the same port (Full-duplex), which essentially doubled the bandwidth.
• Reducing the collision domain to a single switch-port, which eliminated the need for carrier sensing.
• Using the store-and-forward technology's approach of inspecting each packet to intercept corrupt or redundant data, switching eliminated unnecessary transmission that slowed the network.
• By employing address learning, which replaced the inefficient receiving port.

Auto-negotiation regulates the speed and duplex of each port, based on the capability of both devices. Flow-control allows transmission from a 100Mbps node to a 10Mbps node without loss of data. Auto-negotiation and flow-control may require disablement for some networking operations involves legacy equipment. Disabling the auto-negotiation is accomplished by fixing the speed or duplex of a port.

Ethernet Switching Technology supplied higher performance at costs lower than other solutions. Wider bandwidth, no congestion, and the reduction in traffic is why switching is replacing expensive routers and inefficient hubs as the ultimate networking solution.

1.5 Applications

This section provides two network topology examples in which the switch is used. By using the uplink port, the switch can connect with another switch or hub to interconnect other workgroups to form a larger switched network. The distance between two switches via fiber cable can be up to 550 meters (multi-mode fiber) or 10 kilometers (single-mode fiber).

1.5.1 Standalone Workgroup

The switch can be used as a standalone switch to which, computers, servers and printer server are directly connected to form a small workgroup.

Figure 1-2 Standalone ES-1124 Workgroup Example

1.5.2 Bridging

With its large address table (8000 MAC address entries) and high performance, the switch is an ideal solution for department networks to connect to the corporate backbone or for connecting network segments.

The following figure depicts a typical segment bridge application of the switch in an enterprise environment. The two workgroups, the standalone server and the two servers can all communicate with each other and share all network resources.

Figure 1-3 Bridging Example

Chapter 2

Hardware Description and Installation

This section shows two switch installations, describes the hardware of the switch and gives a functional overview of the switch.

The switch is suitable for an office environment where it can be rack mounted on standard EIA racks or as a standalone.

For proper ventilation, allow at least 4 inches (10 cm) of clearance at the front and 3.4 inches (8 cm) at the back of the switch. This is especially important for enclosed rack installations.

2.1 Desktop Installation

Step 1. Make sure the switch is clean and dry.
Step 2. Set the switch on a smooth, leveled and sturdy flat space strong enough to support the weight of the switch and the connected cables. Make sure there is a power outlet nearby.
Step 3. Make sure there is enough clearance around the switch to allow air circulation and the attachment of cables and the power cord.
Step 4. Remove the adhesive backing from the supplied rubber feet.
Step 5. Attach the rubber feet to each corner on the bottom of the switch. These rubber feet help protect the switch from shock or vibration and ensure space between devices when stacking.

Figure 2-1 Attaching Rubber Feet

Do not block the ventilation holes. Leave space between switches when stacking.

2.2 Rack-Mount Installation

The switch can be mounted on an EIA standard size, 19-inch rack or in a wiring closet with other equipment. Follow the steps below to mount your switch on a standard EIA rack using the included rack-mounting kit.

Step 1. Align one bracket with the holes on one side of the switch and secure it with the bracket screws that are smaller than the rack-mounting screws. Similarly, attach the other brackets.

Figure 2-2 Attaching Mounting Brackets and Screws

Step 2. After attaching both mounting brackets, position the switch in the rack by lining up the holes in the brackets with the appropriate holes on the rack. Secure the switch to the rack with the rack-mounting screws.

Figure 2-3 Mounting the ES to an EIA standard 19-inch rack

2.3 Rear Panel

The three-pronged power receptacle is located on the rear panel of the switch. Refer to the Product Specifications for power specification.

Figure 2-4 Rear Panel of the ES-1124

2.4 Rear Panel Power Connection

Connect one end of the supplied power cord to the power receptacle on the back of the switch and the other end to the appropriate power source.

2.5 Front Panel

The front panel of the ES-1124 consists of 24 auto-crossover 10/100Base-TX RJ-45 ports and two auto-detecting Gigabit uplink ports, which may be a Copper Gigabit port or a Mini Gigabit Fiber module (optional). The LEDs are also located on the front panel of the switch.

Figure 2-5 The Front Panel of the ES-1124

2.5.1 10Base-T/100Base-TX RJ-45 auto-negotiating ports

Your switch comes with 24 crossover 10Base-T/100Base-TX RJ-45 ports. The auto-negotiation feature allows the switch to detect the speed of incoming transmission and adjust appropriately without manual intervention. It allows data transfers of either 10 Mbps or 100 Mbps in full-duplex mode.

2.5.2 Auto-crossover MDI/MDIX ports

RJ-45 Ports (Auto MDI/MDIX): 24 auto-crossover 10/100 10Base-T or 100Base-TX connections.

All ports are auto-crossover, that is, auto-MDIX ports (Media Dependent Interface Crossover), so you may use either a straight through Ethernet cable or crossover Ethernet cable for all Ethernet port connections. Auto-crossover ports automatically sense whether they need to function as crossover or straight ports, so crossover cables can connect both computers and switches/hubs.

2.5.3 Gigabit uplink ports

Two Gigabit uplink ports: two auto detecting Giga uplink ports — UTP (unshielded twisted pair) or Gigabit fiber.

Note that when you connect the Mini GBIC to the switch, you must disconnect the Giga copper connection if you have connected it to the device. Otherwise, the switch will not detect the Mini GBIC. While you using Giga copper port or Mini GBIC port, only one of them will work, for example, when a Giga copper port is connected, the Mini GBIC will be disabled.

2.5.4 Front Panel Connections

You can use unshielded twisted pair (UTP) or shielded twisted-pair (STP) Ethernet cables for RJ-45 ports. The following table describes the types of network cable used for the different connection speeds.

Make sure the cable length between connections does not exceed 100 meters (328 feet).
