CHAPTER 1
Getting to Know Your Switch
1.1 Introduction
This chapter describes the key features, benefits and applications of your Switch.
This User’s Guide covers the following m odels: GS1100-8HP, GS1100-16, and GS1100-24. The
Switch is a 10/ 100/ 1000 Mbps multi-port switch that can be used to build high-perform ance
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, departm ents or backbone
computing environm ents for sm all businesses.
The GS1100-8HP has four GbE PoE ports that can supply power to the connected PoE powered
devices.
The GS1100-24 has two mini-GBIC ports for uplink connection. Use m ini-GBIC transceivers in these
slots for connections t o backbone Ethernet switches.
The Switch has a built-in algorithm that autom atically assigns priority to received packets. It can
operate in low power idle m ode in com pliance with I EEE 802.3az Energy Efficient Ethernet (EEE).

detection.
• Supports store-and-forward switching.
• Supports autom atic address learning.

• Support I EEE 802.3af and IEEE 802.3at PoE standards (only GS1100-8HP)
• Full wire speed forwarding rate.
• Supports 802.1p CoS.
• Embedded 8K MAC address table providing 8000 MAC addresses entries.
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 sm all 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 com puters
directly to the Switch’s port or connect other switches to the Swit ch.
In this example, all com puters 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.

1.3.2 Bridging
With its large address table and high perform ance, the Switch is an ideal solution for departm ent
networks to connect to the corporate backbone or for connecting network segm ents.
The following figure depicts a typical segm ent bridge application of the Switch in an enterprise
environm ent. The two networks (RD and Sales), the standalone server and the computers can all
comm unicate with each other and share all network resources.

1.4 Power Over Ethernet (PoE)
The PoE function is available for GS1100-8HP only.
Ports 1 to 4 on the GS1100-8HP are I EEE 802.3at High Power over Ethernet (PoE) com pliant and
can supply power of up to 30W per Ethernet port.
A powered device (PD) is a device such as an access point or a switch, that supports PoE (Power
over Ethernet) so that it can receive power from another device through a 10/ 100/ 1000 Mbps
Ethernet port.

In the figure below, the I P camera and IP phone get their power directly from the Switch. Aside
from minim izing the need for cables and wires, PoE rem oves the hassle of trying to find a nearby
electric outlet to power up devices.

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 power
supply requirem ents on the panel.
Figure 5 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 the GS1100-8HP and GS1100- 16, use the POW ER 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 m ini-GBIC ports. Refer to Section 2.2.3 on page 10 for more inform ation.

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 IEEE 802.3az EEE
The Switch supports the I EEE 802.3az EEE (Energy Efficient Ethernet) standard to help reduce
power consumption. This allows the Switch to go into power saving mode and switch off part of
receive and transm it circuitry when it is not transm itting or receiving data through an Ethernet
connection.
An EEE-enabled device initiates Low Power Idle (LPI) signals to negotiate and wake up the rem ote
device when there is data to be transm itted. To use EEE, both devices should be EEE com pliant.
EEE is configured on a per-system basis in the Switch. I f one of the networking devices that
connect to the Switch doesn't support EEE, EEE m ay not work in the Switch to save power.
The EEE feature is enabled by default on the GS1100-16 and GS1100-24. Press in the I EEE
8 0 2 .3 a z EEE ON / OFF button on the GS1100-8HP front panel to turn on the EEE feature. Disable it
if the rem ote side doesn't support it or you don't want the network perform ance to be im pacted due
to the latency from the additional time required for the sleep and wake transition.
2.2.3 Mini-GBIC Slots (GS1100-24 Only)
These are slots for m ini- GBIC (Gigabit I nterface Converter) transceivers. A transceiver is a single
unit that houses a transm itter and a receiver. The Switch does not com e with transceivers. You
must use transceivers that comply with the Small Form-factor Pluggable (SFP) Transceiver
MultiSource Agreement ( MSA). See the SFF com m ittee’s I NF-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)
2.2.3.1 Transceiver Installation
Use the following steps to install a mini-GBI C transceiver (SFP m odule).
1Insert the transceiver into the slot with the exposed section of PCB board facing down.
2Press the transceiver firm ly until it clicks into place.
