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 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
small businesses.
Figure 1 Front Panel
The GS1100-24 has two mini-GBIC ports for uplink connection. Use mini-GBIC
transceivers in these slots for connections to backbone Ethernet switches.
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 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.
GS1100-16
GS1100-24

Chapter 1 Getting to Know Your Switch

• 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.
• An additional CoS feature (8 queues).
• Embedded 8K MAC address table providing 8000 MAC addresses entries.
Refer to Chapter 4 on page 25 for the product specifications.
1.3 Applications
This section provides two network topology examples in which the Switch is used.
1.3.1 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 Series User’s Guide 11
1.3.2 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 Product Specifications on page 25 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.
For GS1100-16, 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.
The GS1100-24 has two mini-GBIC ports. Refer to Section 2.2.2 on page 14 for
more information.

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.
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 Mini-GBIC Slots (GS1100-24 Only)
These are slots for mini-GBIC (Gigabit Interface Converter) transceivers. A
transceiver is a single unit that houses a transmitter and a receiver. The Switch
does not come with transceivers. You must use transceivers that comply with the
Small Form-factor Pluggable (SFP) Transceiver MultiSource Agreement (MSA). See
the SFF committee’s INF-8074i specification Rev 1.0 for details.
You can change transceivers while the Switch is operating. You can use different
transceivers to connect to Ethernet switches with different types of fiber-optic or
even copper cable connectors.
To avoid possible eye injury, do not look into an operating fiber-
optic module’s connectors.
• Type: SFP connection interface
• Connection speed: 1 Gigabit per second (Gbps)
2.2.2.1 Transceiver Installation
Use the following steps to install a mini-GBIC transceiver (SFP module).
1Insert the transceiver into the slot with the exposed section of PCB board facing
down.
2Press the transceiver firmly until it clicks into place.
3The Switch automatically detects the installed transceiver. Check the LEDs to
verify that it is functioning properly.
4Close the transceiver’s latch (latch styles vary).

Figure 6 Connecting the Fiber Optic Cables
2.2.2.2 Transceiver Removal
Use the following steps to remove a mini-GBIC transceiver (SFP module).
1Remove the fiber optic cables from the transceiver.
2Open the transceiver’s latch (latch styles vary).
3Pull the transceiver out of the slot.

2.2.3 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.
2.2.4 Front Panel LEDs
The LED Indicators give real-time information about the status of the Switch. The
following table provides descriptions of the LEDs.

2.3 Hardware Installation
For GS1100-16, you can place the Switch directly on top of your desk or have it
rack-mounted. For GS110-24, the size is suitable for rack-mounting and you can
refer to Section 2.3.2 on page 18 for instruction. 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 GS1100-16 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 (GS1100-16 Only)
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.

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
The Switch can be mounted on an EIA standard size, 19-inch rack or in a wiring
closet with other equipment. Follow the steps below to mount your Switch on a
stand ard EIA rack using a rack-m ounting ki t.
Rack-mounted Installation Requirements
• Two mounting brackets.
• Eight M3 flat head screws and a #2 Philips screwdriver.
• Four M5 flat head screws and a #2 Philips screwdriver.
Failure to use the proper screws may damage the unit.
Precautions
• Make sure the rack will safely support the combined weight of all the equipment
it contains.
• Make sure the position of the Switch does not make the rack unstable or top-
heavy. Take all necessary precautions to anchor the rack securely before
installing the unit.

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.
