CHAPTER 1
Getting to Know Your Switch
This chapter introduces the main features and applications of the Switch.
1.1 Introduction
The GS1900 series is a new generation Gigabit Ethernet (GbE) Web-Managed Switch.
This User’s Guide covers the following models:
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.

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.

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 62.
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 1038 IP
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, 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
•DHCPv6client

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 33.
• TFTP. Use Trivial File Transfer Protocol for firmware upgrades and configuration backup/restore.
See Section 32.1 on page 213, Section 32.3 on page 215, and Section 32.4 on page 217
• SNMP. The device can be configured by a SNMP manager. See Section 31.3 on page 199.
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.

CHAPTER 2
Hardware Installation and Connection
This chapter shows you how to install and connect the Switch.
2.1 Freestanding Installation
1Make sure the Switch is clean and dry.
2Set 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.
3Make sure there is enough clearance around the Switch to allow air circulation and the attachment
of cables and the power cord.
4Remove the adhesive backing from the rubber feet.
5Attach 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.

2.2 Hardware Installation
See Table 1 on page 15 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 21 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.
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.
