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 e pensive 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 e it 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
duple /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.
 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.
Attac ing 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 e ample,
servers, department switches, and workstation are directly connected to the
MicroGST switches.
