This chapter introduces the main features and applications of the Switch.
1.1 Introduction
Your S witch is a Gigabit Ethernet (GbE) switch with 20, 44 or 48 10/100/1000 Mbps Ethernet ports.
The GS1910-24, GS1910-24HP, XGS1910-24 or XGS1910-48 also has four GbE dual personality
interfaces. A dual personality interface includes one Gigabit Ethernet port and one slot for a miniGBIC transceiver (SFP module) with one port active at a time. The GS1910-48 and GS1910-48HP
have four SFP slots.
The Ethernet ports on the GS1910-24HP or GS1910-48HP are all IEEE802.3at High Power over
Ethernet (PoE) compliant and can supply power of up to 30W per Ethernet port.
CHAPTER 1
Getting to Know Your Switch
The XGS1910-24 or XGS1910-48 is stackable and provides two or four SFP+ slots for uplink or
stacking. They can operate together with other XGS1910-24 or XGS1910-48 switches and need to
be directly connected for stacking. The configurations are done on the master switch, which then
maintains and manages the slave switches in the stack. You can stack up to eight XGS1910-24 or
XGS1910-48 switches per stack.
With its built-in web configurator, managing and configuring the Switch is easy. In addition, the
Switch can also be managed via third-party SNMP management.
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. You can provide a super-fast uplink connection by using the optional 10 Gigabit uplink
module on the Switch.
Figure 1 Bridging Application
1.1.2 High Performance Switching Example
The Switch is ideal for connecting two geographically dispersed networks that need high bandwidth.
In the following example, a company uses the optional 10 Gigabit uplink modules to connect the
headquarters to a branch office network. Within the headquarters network, a company can use
trunking to group several physical ports into one logical higher-capacity link. Trunking can be used
if for example, it is cheaper to use multiple lower-speed links than to under-utilize a high-speed,
but more costly, single-port link.
Figure 2 High Performance Switching

GS1910/XGS1910 Series User’s Guide
1.1.3 Gigabit Ethernet to the Desktop
Internet
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. Use the optional 10 Gigabit uplink module to provide high speed
access to a data server and the Internet. The uplink module supports a fiber-optic connection which
alleviates the distance limitations of copper cabling.
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 3 Gigabit to the Desktop
Chapter 1 Getting to Know Your Switch
1.1.4 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 111.
1.1.4.1 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.
GS1910/XGS1910 Series User’s Guide

Chapter 1 Getting to Know Your Switch
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 4 Shared Server Using VLAN Example
1.1.5 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
addresses. At the time 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, telnet and HTTP 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
• Multicast Listener Discovery (MLD) snooping and proxy
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.
• SNMP. The device can be monitored and/or managed by an SNMP manager.

IP
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.

GS1910/XGS1910 Series User’s Guide
Chapter 1 Getting to Know Your Switch
• 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 Sw itch. Y ou
could simply restore your last configuration.

Hardware Installation and
Connection
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.
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 5 Attaching Rubber Feet
GS1910/XGS1910 Series User’s Guide

Chapter 2 Hardware Installation and Connection
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.
2.2 Mounting the Switch on a Rack
This section lists the rack mounting requirements and precautions and describes
the installation steps.
2.2.1 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.
2.2.1.1 Precautions
• Mak e sure the r ack will safely sup port the combined weight of all the equipment
it contains.
• Make sure the position of the Switch does not make the rack unstable or topheavy. Take all necessary precautions to anchor the rack securely before
installing the unit.
2.2.2 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.

switches using Category 5/5e/6 1000Base-T Ethernet cables.
Use an 8-wire Ethernet cable for Gigabit connections. Using a 4-wire
Ethernet cable limits your connection to 100 Mbps. Note that the
connection speed also depends on what the Ethernet device at the
other end can support.
•SFP Slots:
Use SFP transceivers in these ports for 1000Base-X fiber-optic
connections to backbone Ethernet switches.
Use SFP transceivers in these slots for fiber-optic or copper connections
to backbone Ethernet switches.
Use SFP+ transceivers in these slots for fiber-optic connections to
backbone Ethernet switches.
firmware upgrade using an RS-232 cable.
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 straightthrough 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
• Dual Personality Interface: Fiber-optic module first
GS1910/XGS1910 Series User’s Guide
17
Chapter 3 Hardwar e Over vie w
3.1.2 Dual Personality Interfaces
There are four dual personality interfaces, comprising four 1000Base- T/SFP combo
ports. For each interface you can connect either to the 1000Base- T port or the SFP
slot. If an SFP transceiver is inserted in the SFP slot, the corresponding 1000BaseT port will be disabled.
Note: Connect the 1000Base-T RJ-45 port only after the transceiver is removed from
the corresponding SFP slot.
3.1.3 SFP/SFP+ Slots
These are slots for Small Form-Factor Pluggable (SFP) or SFP+ transceivers. The
SFP is also referred to as a mini-GBIC. The SFP+ (SFP Plus) is an enhanced
version of the SFP and supports data rates of 10 Gbps. A transceiver is a single
unit that houses a transmitter and a receiver. Use a transceiver to connect a fiberoptic cable to the Switch. 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
connectors.
• Type: SFP connection interface
• Connection speed: 1 Gigab it per second ( Gbps) or 10 Gig abit per second (Gbps )
To avoid possible eye injury, do not look into an operating fiberoptic module’s connectors.
3.1.3.1 Transceiver Installation
Use the following steps to install a transceiver (SFP or SFP+ module).
