Getting to Know Your Switch
Introduction
The switch is a multi-port switch that can be used to build high-
performance switched networks. The switch is a store-and-forward device
that offers low latency for high-speed networking. The switch is designed
for SOHO (Small Office Home Office) businesses.
Standalone Workgroup Application
The switch can be used as a standalone switch to which computers, servers
and print server are directly connected to form a small workgroup.
Standalone Workgroup Example
Hardware Installation
The switch is suitable for an office environment where it can be placed on
a desktop.
Step 1. Make sure the switch is clean and dry.
Step 2. Set the switch on a smooth, level 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. Use only the supplied power adaptor to connect your switch to
a power source. Refer to the label on the power adapter for
more information.

Do not block the ventilation holes.
Hardware Connection
The power and the Ethernet ports are located on the rear panel.
Rear PanelGS-105A
Rear Panel: GS-108A
Power Connection
Connect one end of the supplied power adaptor to the power port on the
rear panel of the switch and the other end to the appropriate power source.
The PWR LED turns on.
RJ-45 Auto-negotiating Ports
The switch comes with 5 or 8 10/100/1000M RJ-45 ports depending on
the model of your switch. 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 10 Mbps, 100
Mbps or 1000 Mbps in either half-duplex or full-duplex mode depending
on your Ethernet network.

Auto-crossover Ethernet Ports
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.
Refer to the Product Specifications section for the types of network cable
used for the different connection speeds.
Front Panel LEDs
The LEDs on the front panel indicate the real-time status of the switch.
Front Panel LED: GS-108A
