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.

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.
GS1900 Series User’s Guide

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

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.

3.2.1 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.

9.1 Overview
This section provides information for VLAN in Monitor.
A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into multiple logical
networks. Devices on a logical network belong to one group. A device can belong to more than one
group. With VLAN, a device cannot directly talk to or hear from devices that are not in the same
group(s); the traffic must first go through a router.
In MTU (Multi-Tenant Unit) applications, VLAN is vital in providing isolation and security among the
subscribers. When properly configured, VLAN prevents one subscriber from accessing the network
resources of another on the same LAN, thus a user will not see the printers and hard disks of another user
on the same network.
VLAN also increases network performance by limiting broadcasts to a smaller and more manageable
logical broadcast domain. In traditional switched environments, all broadcast packets go to each and
every individual port. With VLAN, all broadcasts are confined to a specific broadcast domain.

9.2.3 VLAN Port
Port-based VLANs are VLANs where the packet forwarding decision is based on the destination MAC
address and its associated port. Port-based VLANs require allowed outgoing ports to be defined for
each port. Therefore, if you wish to allow two subscriber ports to talk to each other, for example,
between conference rooms in a hotel, you must define the egress (an egress port is an outgoing port,
that is, a port through which a data packet leaves) for both ports. Port-based VLANs are specific only to
the Switch on which they were created.

9.3 Guest VLAN
When 802.1x port authentication is enabled on the Switch and its ports, clients that do not have the
correct credentials are blocked from using the port(s). You can configure your Switch to have one VLAN
that acts as a guest VLAN. If you enable the guest VLAN (102 in the example) on a port (2 in the
example), the user (A in the example) that is not IEEE 802.1x capable or fails to enter the correct
username and password can still access the port, but traffic from the user is forwarded to the guest
VLAN. That is, unauthenticated users can have access to limited network resources in the same guest
VLAN, such as the Internet. The rights granted to the Guest VLAN depends on how the network
administrator configures switches or routers with the guest network feature.

10.1 Overview
This section provides information for MAC Table in Monitor.
The MAC Table screen (a MAC table is also known as a filtering database) shows how frames are
forwarded or filtered across the Switch’s ports. When a device (which may belong to a VLAN group)
sends a packet which is forwarded to a port on the Switch, the MAC address of the device is shown on
the Switch’s MAC Table. It also shows whether the MAC address is dynamic (learned by the Switch) or
static (manually entered in the Static MAC Forwarding screen).
The Switch uses the MAC Table to determine how to forward frames. See the following figure.
1 The Switch examines a received frame and learns the port from which this source MAC address came.
2 The Switch checks to see if the frame's destination MAC address matches a source MAC address
already learned in the MAC Table.
CHAPTER 10
Monitor: MAC Table
• If the Switch has already learned the port for this MAC address, then it forwards the frame to that port.
• If the Switch has not already learned the port for this MAC address, then the frame is flooded to all
ports. Too much port flooding leads to network congestion.
• If the Switch has already learned the port for this MAC address, but the destination port is the same as
the port it came in on, then it filters the frame.

Monitor: Link Aggregation
11.1 Overview
This section provides information for Link Aggregation in Monitor.
Link aggregation (trunking) is the grouping of physical ports into one logical higher-capacity link. You
may want to trunk ports 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. However, the more ports you aggregate then the fewer
available ports you have. A trunk group is one logical link containing multiple ports.
The Switch supports both static and dynamic link aggregation.
Note: In a properly planned network, it is recommended to implement static link aggregation
only. This ensures increased network stability and control over the trunk groups on your
Switch.

12.1 Overview
This section provides information for Loop Guard in Monitor.
Loop guard is designed to handle loop problems on the edge of your network. This can occur when a
port is connected to a Switch that is in a loop state. Loop state occurs as a result of human error. It
happens when two ports on a switch are connected with the same cable. When a switch in loop state
sends out broadcast messages the messages loop back to the switch and are re-broadcast again and
again causing a broadcast storm.
If a switch (not in loop state) connects to a switch in loop state, then it will be affected by the switch in
loop state in the following way:
• It will receive broadcast messages sent out from the switch in loop state.
• It will receive its own broadcast messages that it sends out as they loop back. It will then re-broadcast
those messages again.
CHAPTER 12
Monitor: Loop Guard
The following figure shows port N on switch A connected to switch B. Switch B is in loop state. When
broadcast or multicast packets leave port N and reach switch B, they are sent back to port N on A as
they are rebroadcast from B.
Figure 70 Switch in Loop State
The loop guard feature checks to see if a loop guard enabled port is connected to a switch in loop
state. This is accomplished by periodically sending a probe packet and seeing if the packet returns on
the same port. If this is the case, the Switch will shut down the port connected to the switch in loop state.
The following figure shows a loop guard enabled port N on switch A sending a probe packet P to switch
B. Since switch B is in loop state, the probe packet P returns to port N on A. The Switch then shuts down
port N to ensure that the rest of the network is not affected by the switch in loop state.
GS1900 Series User’s Guide
79
Chapter 12 Monitor: Loop Guard
Figure 71 Loop Guard - Probe Packet
The Switch also shuts down port N if the probe packet returns to switch A on any other port. In other
words loop guard also protects against standard network loops. The following figure illustrates three
switches forming a loop. A sample path of the loop guard probe packet is also shown. In this example,
the probe packet is sent from port N and returns on another port. As long as loop guard is enabled on
port N. The Switch will shut down port N if it detects that the probe packet has returned to the Switch.

13.1 Overview
This section provides information for Multicast in Monitor.
Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender to 1 recipient) or
Broadcast (1 sender to everybody on the network). Multicast delivers IP packets to just a group of hosts
on the network.
IGMP (Internet Group Management Protocol) is a network-layer protocol used to establish membership
in an IPv4 multicast group - it is not used to carry user data. Refer to RFC 1112, RFC 2236 and RFC 3376 for

Path cost is the cost of transmitting a frame on to a LAN through that port. It is
recommended to assign this value according to the speed of the bridge. The slower the
media, the higher the cost.

14.2.5 STP Statistics
(R)STP detects and breaks network loops and provides backup links between switches, bridges or
routers. It allows a Switch to interact with other (R)STP-compliant switches in your network to ensure that
only one path exists between any two stations on the network.
The Switch uses IEEE 802.1w RSTP (Rapid Spanning Tree Protocol) that allows faster convergence of the
spanning tree than STP (while also being backwards compatible with STP-only aware bridges). In RSTP,
topology change information is directly propagated throughout the network from the device that
generates the topology change. In STP, a longer delay is required as the device that causes a topology
change first notifies the root bridge and then the root bridge notifies the network. Both RSTP and STP flush
unwanted learned addresses from the filtering database. In RSTP, the port states are Discarding,
Learning, and Forwarding.

16.2 Port Security
Port security allows only packets with dynamically learned MAC addresses and/or configured static
MAC addresses to pass through a port on the Switch. The Switch can learn up to 8K MAC addresses in
total with no limit on individual ports; system total MAC address entry is 8K. Static MAC address still can
be configured when port security is enabled; the function of port security is concerned with dynamic
mac address learn action. When total MAC address entry is 8k, static MAC can't be configured.
