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 and Connection
The switch is suitable for an office environment where it can be placed on
a desktop.

Desktop Installation
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 the supplied power adapter 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.
Rear Panel 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.
Port Connection
For GS-105, the Ethernet ports are located on the rear panel. For GS-108,
the Ethernet ports are located on the front panel.

RJ-45 Auto-negotiating Ports
Your 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-sensing (MDI/MDIX) Ethernet Ports
Each Ethernet port allows you to connect to a computer or to a hub using
either a straight-through or a crossover Ethernet cable.
The following table describes the types of network cable used for the
different connection speeds.
Table 1 Ethernet Cable Type
SPEED NETWORK CABLE TYPE
10 Base-T 100Ω2-pair UTP/STP Category 3, 4 or 5
100 Base-TX 100Ω2-pair UTP/STP Category 5
1000 Base-T 100Ω4-pair UTP/STP Category 5
Cable length between connections must not
exceed 100 meters (328 feet).
Front Panel LEDs
The LEDs on the front panel indicate the real-time status of the switch.
Figure 3 Front Panel LED: GS-108
The following table gives descriptions of the LEDs.
