CHAPTER 1
Getting to Know Your Switch
1.1 Introduction
This chapter describes the key features, benefits and applications of your Switch.
The Switch is a 10/100/1000 Mbps Gigabit multi-port switch that can be used to
build high-performance switched workgroup networks. The Switch is a store-and-
forward device that offers low latency for high-speed networking. The Switch is
designed for workgroups, departments or backbone computing environments for
SME (small, medium enterprise) businesses.
Figure 1 Front Panel
The Switch has a built-in algorithm that automatically assigns priority to received
packets. It can operate in low power idle mode in compliance with draft IEEE
802.3az Energy Efficient Ethernet (EEE).
1.2 Features
The following are the essential features of the Switch.
• Conforms to IEEE 802.3, 802.3u, 802.3ab and 802.3x standards.
• Auto-negotiating 10/100/1000 Mbps Ethernet RJ-45 ports.
• Auto-sensing crossover for all 10/100/1000 Mbps Ethernet RJ-45 ports.
• Supports N-Way protocol for speed (10/100/1000 Mbps) and duplex mode
(Half/Full) auto-detection
• Supports store-and-forward switching.
• Supports automatic address learning.

• Full wire speed forwarding rate.
• Embedded 8K MAC address table providing 8000 MAC addresses entries.
Refer to Chapter 4 on page 15 for the product specifications.
1.3 Package Contents
Compare the contents of your Switch package with the checklist below. If any item
is missing or damaged, please contact your local dealer.
• An Ethernet switch
•Powercord

1.4 Applications
This section provides two network topology examples in which the Switch is used.
1.4.1 Standalone Workgroup
In this application, the Switch is an ideal solution for small networks where rapid
growth can be expected in the near future.
The Switch can be used standalone for a group of heavy traffic users. You can
connect computers directly to the Switch’s port or connect other switches to the
Switch.
In this example, all computers can share high-speed applications on the server. To
expand the network, simply add more networking devices such as switches,
routers, computers, print servers etc.
Figure 2 Standalone Workgroup Example

Chapter 1 Getting to Know Your Switch
GS1100-16 User’s Guide 5
1.4.2 Bridging
With its large address table 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 networks (RD and Sales), the standalone
server and the computers can all communicate with each other and share all
network resources.

Hardware Description and
Connection
2.1 Rear Panel
The three-pronged power receptacle is located on the rear panel of the Switch.
Refer to the Appendix on page 15 for power specification.
Figure 4 Rear Panel
2.1.1 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. Use the ON/OFF
switch to have the Switch power on or off.
2.2 Front Panel
The front panel of the Switch includes the auto-negotiating 10 Base-T/100 Base-
TX/1000 Base-T RJ-45 ports and the LEDs.
2.2.1 RJ-45 Auto-negotiating Ports
The 10 Base-T/100 Base-TX/1000 Base-T RJ-45 ports are auto-negotiating and
auto-crossover.

Chapter 2 Hardware Description and Connection
GS1100-16 User’s Guide

An auto-negotiating port can detect and adjust to the optimum Ethernet speed
(10/100/1000 Mpbs) and duplex mode (full duplex or half duplex) of the
connected device.
An auto-crossover (auto-MDI/MDI-X) port automatically works with a straight-
through or crossover Ethernet cable.
2.2.2 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. .
You can use either crossover or straight-through cables for all the ports.
2.2.3 Front Panel LEDs
The LED Indicators give real-time information about the status of the Switch. The
following table provides descriptions of the LEDs.
Figure 5 Front Panel LEDs
The following table describes the LEDs.

2.3 Hardware Installation
You can place the Switch directly on top of your desk. Take note of the following:
• The Switch should have a minimum 25 mm space around it for ventilation.
• The Switch should be placed in a desk that has a level surface and that is able to
support the weight of the Switch.
To start using it, simply connect the power cables and turn on the Switch.
Note: The Switch is a desktop device, but it is also rackmountable and wall-
mountable. Ask an authorized technician to attach the Switch to the rack/
wall.
2.3.1 Wall-mounting
Do the following to attach your Switch to a wall.
1Screw the two screws provided with your Switch into the wall 150 mm apart (see
the figure in step 2). Use screws with 6 mm ~ 8 mm (0.24" ~ 0.31") wide heads.
Do not screw the screws all the way in to the wall; leave a small gap between the
head of the screw and the wall.
The gap must be big enough for the screw heads to slide into the screw slots and
the connection cables to run down the back of the Switch.
Note: Make sure the screws are securely fixed to the wall and strong enough to hold
the weight of the Switch with the connection cables.
LINK/
ACT Green On The port is connected to an Ethernet network.
Blinking The port is receiving or transmitting data.
Off The port is not connected to an Ethernet network.

2Align the holes on the back of the Switch with the screws on the wall. Hang the
Switch on the screws.
The Switch should be wall-mounted horizontally. The Switch's side
panels with ventilation slots should not be facing up or down as
this position is less safe.
2.3.2 Rack Mounting
Attaching the Mounting Brackets to the Switch
1Position a mounting bracket on one side of the Switch, lining up the four screw
holes on the bracket with the screw holes on the side of the Switch.
Figure 6 Attaching the Mounting Brackets
2Using a #2 Philips screwdriver, install the M3 flat head screws through the
mounting bracket holes into the Switch.
3Repeat steps 1and 2to install the second mounting bracket on the other side of
the Switch.
4You may now mount the Switch on a rack. Proceed to the next section.
