See the datasheet for a full list of firmware features available on the Switch.
1.1.1 Bridging Example
In this example the Switch connects different company departments (RD and Sales) to the corporate
backbone. It can alleviate bandwidth contention and eliminate server and network bottlenecks. All
users that need high bandwidth can connect to high-speed department servers via the Switch.
GS1900 Series User’s Guide
16
Chapter 1 Getting to Know Your Switch
Figure 1 Bridging Application
1.1.2 Gigabit Ethernet to the Desktop
The Switch is an ideal solution for small networks which demand high bandwidth for a group of heavy
traffic users. You can connect computers and servers 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 and access the Internet.
To expand the network, simply add more networking devices such as switches, routers, computers, print
servers and so on.
Figure 2 Gigabit to the Desktop
1.1.3 IEEE 802.1Q VLAN Application Example
A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into multiple logical
networks. Stations on a logical network belong to one or more groups. With VLAN, a station cannot
directly talk to or hear from stations that are not in the same group(s) unless such traffic first goes through
a router.
For more information on VLANs, refer to Chapter 9 on page 68.
GS1900 Series User’s Guide
17
Chapter 1 Getting to Know Your Switch
1.1.3.1 Tag-based VLAN Example
Ports in the same VLAN group share the same frame broadcast domain, thus increasing network
performance by reducing broadcast traffic. VLAN groups can be modified at any time by adding,
moving or changing ports without any re-cabling.
Shared resources such as a server can be used by all ports in the same VLAN as the server. In the
following figure only ports that need access to the server need to be part of VLAN 1. Ports can belong to
other VLAN groups too.
Figure 3 Shared Server Using VLAN Example
1.1.4 IPv6 Support
IPv6 (Internet Protocol version 6), is designed to enhance IP address size and features. The increase in
IPv6 address size to 128 bits (from the 32-bit IPv4 address) allows up to 3.4 x 10
of writing, the Switch supports the following features.
• Static address assignment and stateless auto-configuration
• Neighbor Discovery Protocol (a protocol used to discover other IPv6 devices in a network)
• Remote Management using PING, SNMP, HTTP and TFTP services
• ICMPv6 to report errors encountered in packet processing and perform diagnostic functions, such as
"PING”
• IPv4/IPv6 dual stack; the Switch can run IPv4 and IPv6 at the same time
• DHCPv6 client
1.2 Ways to Manage the Switch
Use any of the following methods to manage the Switch.
• Web Configurator. This is recommended for everyday management of the Switch using a (supported)
web browser. See Chapter 5 on page 36.

IP addresses. At the time
GS1900 Series User’s Guide

Chapter 1 Getting to Know Your Switch
• TFTP. Use Trivial File Transfer Protocol for firmware upgrades and configuration backup/restore. See
Section 33.1 on page 222, Section 33.3 on page 225, and Section 33.4 on page 226
• SNMP. The device can be configured by a SNMP manager. See Section 32.3 on page 209.
1.3 Good Habits for Managing the Switch
Do the following things regularly to make the Switch more secure and to manage the Switch more
effectively.
• Change the password. Use a password that’s not easy to guess and that consists of different types of
characters, such as numbers and letters.
• Write down the password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it). Restoring an earlier working
configuration may be useful if the device becomes unstable or even crashes. If you forget your
password, you will have to reset the Switch to its factory default settings. If you backed up an earlier
configuration file, you would not have to totally re-configure the Switch. You could simply restore your
last configuration.

Hardware Installation and
This chapter shows you how to install and connect the Switch.
2.1 Freestanding Installation
1 Make sure the Switch is clean and dry.
2 Set the Switch on a smooth, level surface strong enough to support the weight of the Switch and the
connected cables. Make sure there is a power outlet nearby.
CHAPTER 2
Connection
3 Make sure there is enough clearance around the Switch to allow air circulation and the attachment of
cables and the power cord.
4 Remove the adhesive backing from the rubber feet.
5 Attach the rubber feet to each corner on the bottom of the Switch. These rubber feet help protect the
Switch from shock or vibration and ensure space between devices when stacking.
Figure 4 Attaching Rubber Feet
Note: Do NOT block the ventilation holes. Leave space between devices when stacking.
Note: For proper ventilation, allow at least 4 inches (10 cm) of clearance at the front and 3.4
inches (8 cm) at the back of the Switch. This is especially important for enclosed rack
installations.
GS1900 Series User’s Guide
20
Chapter 2 Hardware Installation and Connection
2.2 Hardware Installation
See Table 1 on page 16 for a comparison of the hardware installation methods of each model:
Note: Ask an authorized technician to attach the Switch to the rack/wall.
Refer to Section 2.2.2 on page 22 for rack-mounting instructions. Take note of the following:
• The Switch should have a minimum 25 mm space around it for ventilation.
• The Switch should be placed on 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.
2.2.1 Wall Mounting
Do the following to attach your Switch to a wall.
See the following table for how far apart to place the screws.
Table 2 Distance between the centers of the holes for wall mounting
GS1900-8 GS1900-8HP GS1900-10HP GS1900-16 GS1900-24E
176 mm 176 mm 176 mm 148 mm 207 mm
Screw the two screws provided with your Switch into the wall (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.
Align the holes on the back of the Switch with the screws on the wall. Hang the Switch on the screws.
GS1900 Series User’s Guide
21
Chapter 2 Hardware Installation and Connection
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.
2.2.2 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 standard EIA rack using a rack-mounting
kit.
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
1 Position 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.

3.1.1 Ethernet Ports
The Switch has 1000Base-T auto-negotiating, auto-crossover Ethernet ports. In 10/100/1000 Mbps Gigabit
Ethernet, the speed can be 10Mbps, 100 Mbps or 1000 Mbps. The duplex mode can be both half or full
duplex at 100 Mbps and full duplex only at 1000 Mbps.
An auto-negotiating port can detect and adjust to the optimum Ethernet speed (10/100/1000 Mbps)
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.
3.1.1.1 Default Ethernet Settings
The factory default negotiation settings for the Ethernet ports on the Switch are:
• Speed: Auto
•Duplex: Auto
• Flow control: Off
Chapter 3 Hardware Overview
3.1.2 SFP Slots
These are slots for Small Form-Factor Pluggable (SFP) transceivers. A transceiver is a single unit that
houses a transmitter and a receiver. Use a transceiver to connect a fiber-optic cable to the Switch. The
Switch does not come with transceivers. You must use transceivers that comply with the Small FormFactor 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 connectors.
• Type: SFP connection interface
• Connection speed: 1 Gigabit per second (Gbps)
To avoid possible eye injury, do not look into an operating fiber-optic
module’s connectors.
3.1.2.1 Transceiver Installation
Use the following steps to install a transceiver.
GS1900 Series User’s Guide

3.2.1 Power Connection
Make sure you are using the correct power source and that no objects obstruct the airflow of the fans.
The Switch uses two power supply modules, one of which is redundant, so if one power module fails the
system can operate on the remaining module.
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 Switches with a power switch (see Table 1 on page 16), use the POWER ON/OFF switch to have the
Switch power on or off.
Connecting the Power
Use the following procedures to connect the Switch to a power source after you have installed it in a
rack.
Note: Use the included power cord for the AC power connection.
