1. Introduction

Gigabit Ethernet over copper technology is a proven cost-effective way for

network equipment to be upgraded from Fast Ethernet to Gigabit speeds. The

need of expensive fiber optic cabling for Gigabit speeds is eliminated by using

standard 4-pair Category 5e copper cabling. This technology creates

high-speed backbone connections between switches, servers, databases, and

workstations.

Unicom's 5 and 8 Port Desktop Gigabit Ethernet Switches are an ideal solution

for solving traffic congestion at the core of the network. They offer

Auto-Negotiation 10/100/1000Base-T Gigabit Ethernet ports that can

significantly improve your network backbone performance. They will also fit

into any enterprise level network to act as an exit to the backbone switch.

The 5 and 8 Port Gigabit Ethernet Switches feature an Auto MDI/MDIX

function for each port as well as store-and-forward switching and can

auto-learn and store source addresses on a 4K MAC address table.

2.Hardware Description

This Section describes the hardware of the MicroGST/5 and 8 switches.

The physical dimensions of each switch are 165 x 100 x 32.5 mm

(L x W x H)

Front and Rear Panel

The Front Panel of the MicroGST/5 and 8 switches consists of a power LED

indicator for the unit and LED indicators (100/1000, Link/Activity, Full

duplex/Collision) for each Gigabit port.

Figure 2-1. The Front Panel of the MicroGST/5 and 8 switches

The Rear Panel of the MicroGST switches consists of Auto-Negotiation

10/100/1000Mbps Ethernet RJ-45 connectors.

ν RJ-45 Ports (Auto MDI/MDIX): Five or eight Auto-Negotiation 10/100/1000

Mbps Ethernet RJ-45 connectors

[Auto MDI/MDIX means that you can connect to another switch or workstation

with either straight-through or crossover cabling.]

LED Indicators

The LED Indicators gives real-time monitoring of system operating status.

There are three LED indicators (100/1000, LNK/ACT, FDX/COL) for each

Gigabit port and one Power LED for the unit. The following table provides

descriptions of each LED status.

3. Installation

Set the Switch on a sufficiently large flat space with a power outlet nearby. The

surface should be clean, smooth, level, and sturdy. Ensure there is enough

clearance around the Switch to allow air circulation and the attachment of the

power cord and cables.

Attaching Rubber Feet

A. Make sure mounting surface on the bottom of the Switch is grease and

dust free.

B. Remove adhesive backing from your Rubber Feet.

C. Apply the Rubber Feet to each corner on the bottom of the Switch. These

footpads protect the Switch from shock and vibration.

Power On

Connect the power adapter cable to the power socket on the rear panel of the

Switch. The other end of the power cord connects to the power outlet. Check

the power indicator on the front panel to make sure if power is properly

supplied.

4. Network Application

This section provides a sample of network topology in which the MicroGST/5

and 8 switches are used. In general, the MicroGST switches are designed as

high-bandwidth backbone switches.

You can use the MicroGST switches to connect servers, switches,

workstations, and PCs to each other by connecting these devices directly to

the Switch. The Switch automatically learns node addresses, which are

subsequently used to filter and forward all traffic based on the destination

address.

For enterprise networks where large data broadcasts are constantly processed,

this switch is an ideal link between departmental switches and the core switch.

All workstations can connect to departmental switches and those switches are

then connected to the MicroGST/5 and 8 switches. Now all the devices in this

network can communicate with each other. Connecting servers to the core

switch is important because it allows each workstation to access the server’s

data.

This switch is designed for backbone connectivity. In the above example,

servers, department switches, and workstation are directly connected to the

MicroGST switches.
