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 models: GS1100-8HP, GS1100-16, GS1100-24, GS1100-24E
and GS1100-10HP. 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 fanless and designed for workgroups,
departments or backbone computing environments for small businesses.
The GS1100-8HP has four GbE PoE ports that can supply power to the connected PoE powered
devices.
The GS1100-10HP has eight GbE PoE ports that can supply power to the connected PoE powered
devices.
The GS1100-24 and GS1100-10HP have two SFP slots for uplink connection. Use SFP transceivers
in these slots for 100Mbps or 1Gbps 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).

1.3 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
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 (R&D and Sales), the standalone server and the computers can all
communicate with each other and share all network resources.

1.4 Power Over Ethernet (PoE)
The PoE function is available for GS1100-8HP and GS1100-10HP.
Ports 1 to 4 on the GS1100-8HP are IEEE 802.3at High Power over Ethernet (PoE) compliant and
can supply power of up to 30W per Ethernet port and up to the total PoE power budget per Switch.
Ports 1 to 8 on the GS1100-10HP support both the IEEE 802.3af Power over Ethernet and IEEE
802.3at High Power over Ethernet standards. The ports supply power of up to 30W per Ethernet
port and up to the total PoE power budget per Switch.
The Switch is Power Sourcing Equipment (PSE) because it provides a source of power via its
Ethernet ports. A powered device (PD) is a device such as an access point or an IP phone, 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 IP camera and IP phone get their power directly from the Switch. Aside
from minimizing the need for cables and wires, PoE removes the hassle of trying to find a nearby
electric outlet to power up devices.

Hardware Description and Connection
2.1 Rear Panel
The power receptacle is located on the rear panel of the Switch. Refer to the power supply
requirements on the panel.
Figure 5 Rear Panel
2.1.1 Rear Panel Power Connection
Connect one end of the supplied power cord or power adaptor to the power receptacle on the back
of the Switch and the other end to the appropriate power source.
For the GS1100-8HP, GS1100-16, GS1100-24E and GS1100-10HP, use the POWER 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 and GS1100-10HP have two SFP slots. Refer to Section 2.2.3 on page 9 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 IEEE 802.3az EEE
The Switch supports the IEEE 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 transmit circuitry when it is not transmitting or receiving data through an Ethernet
connection.
An EEE-enabled device initiates Low Power Idle (LPI) signals to negotiate and wake up the remote
device when there is data to be transmitted. To use EEE, both devices should be EEE compliant.
EEE is configured on a per-system basis in the Switch. If one of the networking devices that
connect to the Switch doesn't support EEE, EEE may not work in the Switch to save power.
Press in the IEEE 802.3az EEE ON/OFF button on the front panel to turn on the EEE feature.
Disable it if you don't want the network performance to be impacted due to the latency from the
additional time required for the sleep and wake transition or if the remote side doesn't support it.
2.2.3 SFP Slots (GS1100-24 and GS1100-10HP)
These are slots for Small Form-factor Pluggable (SFP) 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: 100 Megabit per second (Mbps) or 1 Gigabit per second (Gbps)

2.2.3.1 Transceiver Installation
Use the following steps to install a 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).
5Connect the fiber optic cables to the transceiver.
