Desktop Installation
Set the switch on a sufficiently large flat space with a power outlet nearby. The
surface where you put the switch should be clean, smooth, level and sturdy.
Make sure there is enough clearance around the switch to allow attachment of
cables, power cord and allow air circulation.
Attaching Rubber Pads
A. Make sure mounting surface on the bottom of the switch is grease and dust
free.
B. Remove adhesive backing of Rubber Pads.
C. Apply the Rubber Pads to each corner on the bottom of the switch and these
footpads can prevent the switch from shock/vibration.
Rack-mounted Installation
The 24 10/100/1000TX plus 4 Mini GBIC Web Managed Switch come with a
rack-mounted kid and can be mounted in an EIA standard size/19-inch Rack. The
11
switch can be placed in a wiring closet with other equipment.
Perform the following steps to rack mount the switch:
1. Position one bracket to align with the holes on one side of the switch and
secure it with the smaller bracket screws. Then attach the remaining bracket
to the other side of the switch.
2. After attached mounting brackets, position the 24 10/100/1000TX plus 4 Mini
GBIC Web Managed switch in the rack by lining up the holes in the brackets
with the appropriate holes on the rack. Secure the switch to the rack with a
screwdriver and the rack-mounting screws.
[NOTE]
For proper ventilation, allow about at least 4 inches (10 cm) of clearance
on the front and 3.4 inches (8 cm) on the back of the Switch. This is especially
important for enclosed rack installation.
Power On
Connect the power cord to the power socket on the rear panel of the switch. The
other side of power cord connects to the power outlet. The internal power supply
of the switch works with voltage range of AC in the 100-240VAC, frequency
50~60Hz. Check the power indicator on the front panel to see if power is properly
supplied.

Network Application
This section provides few samples of network topology in witch the switch is used.
In general, the 24 10/100/1000TX plus 4 Mini GBIC Web Managed Switch is
designed as a segment switch. That is, with its large address table (8K MAC
address) and high performance, it is ideal for interconnecting networking
segments.
PC, workstations and servers can communicate each other by directly connecting
with 24 10/100/1000TX plus 4 Mini GBIC Web Managed Switch. The switch
automatically learns nodes address, which are subsequently used to filter and
forward all traffic based on the destination address.
By using Uplink port, the switch can connect with another switch or hub to
interconnect other small-switched workgroups to form a larger switched network.
Meanwhile, you can also use fiber ports to connect switches.
Small Workgroup
The 24 10/100/1000TX plus 4 Mini GBIC Web Managed Switch can be used as a
standalone switch for personal computers, server and printer server which are
directly connected to form a small workgroup.

management of the certain switch.
About Web-based Management
On the CPU board of the switch there is an embedded HTML web site residing in
flash memory, which offers advanced management features and allow users to
manage the switch from anywhere in the network through a standard browser
such as Microsoft Internet Explorer.
The Web-Based Management supports Internet Explorer 5.0. And, it is applied
with Java Applets for reducing network bandwidth consumption, enhance access
speed and present an easy viewing screen.
[NOTE]
By default, IE5.0 or later version does not allow Java Applets to activate
sockets. In fact, the user has to explicitly modify the browser setting to enable
Java Applets to operate network ports.

VLAN Setting
A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast
domain, which would allows user to isolate network traffic so only the members of
VLAN will receive traffic from the same members of VLAN. Basically, creating a
VLAN from a switch is logically equivalent of reconnecting a group of network
devices to another Layer 2 switch. However, all the network devices are still
plugged into the same switch physically.
Assigning the VLAN ID by inputting a number (from 1~4095) into the VID
text-box
Grouping the members of VLAN by checking the check-box to make the
selection

Aggregation
Port trunk allows multiple links to be bundled together and act as a single
physical link for increased throughput. It provides load balancing and redundancy
of links in a switched inter-network. Actually, the link does not have an inherent
total bandwidth equal to the sum of its component physical links. Traffic in a trunk
is distributed across an individual link within the trunk in a deterministic method
23
that called a hash algorithm. Traffic pattern on the network should be considered
carefully before applying it. When a proper hash algorithm is used, traffic is kind
of randomly decided to be transmitted across either link within the trunk and load
balancing will be seen.
Select the group members( Normal means the port is not the trunk port)
Click Apply to apply the configuration
Or, click Refresh to reset the configuration before applying
Aggregation interface
LACP Setting
The Link Aggregation Control Protocol (LACP) provides a standardized which
means for exchanging information between Partner Systems on a link to allow
their Link Aggregation Control instances to reach agreement on the identity of the
Link Aggregation Group to which the link belongs, move the link to that Link
Aggregation Group, and enable its transmission and reception functions in an
24
orderly manner. Link aggregation allow user grouping up to eight consecutive
ports into a single dedicated connection. This feature can expand bandwidth to a
device on the network.
LACP operation requires full-duplex mode,

IGMP Snooping
The Internet Group Management Protocol (IGMP) is an internal protocol of the
Internet Protocol (IP) suite. IP manages multicast traffic by using switches,
routers, and hosts that support IGMP. Enabling IGMP allows the ports to detect
30
IGMP queries and report packets and manage IP multicast traffic through the
switch.
The switch support IP multicast that IGMP protocol can be enabled on switch
then displays the IGMP snooping information. IP multicast addresses range from
224.0.0.0 through 239.255.255.255.
IGMP Enable:

Router Ports:
A static router port. It is a port that has a multicast router,
which has a connection to the internet, attached to it. Selecting a router port
will allow multicast packets coming from the router to be propagated through
the network, as well as allowing multicast messages (IGMP) coming from the
network to be propagated to the router. All IGMP Report packets will be
forwarded to the router port, and IGMP queries (from the router port) will be
flooded to all ports. All UDP multicast packets will be forwarded to the router
port because routers do not send IGMP reports or implement IGMP
snooping.

Troubleshooting
This section is intended to help user to solve the most common problems on
the24 10/100/1000TX plus 4 Mini GBIC Web Managed Switch.
Incorrect connections
The switch port can auto detect straight or crossover cable when the switch link
with other Ethernet device. For the RJ-45 connector should use correct UTP or
STP cable, 10/100Mbps port use 2 pairs twisted cable and Gigabit 1000T port
use 4 pairs twisted cable. If the RJ-45 connector is not correct pin on right
position then the link will fail. For fiber connection, please notice that fiber cable
mode and fiber module should be match.
Faulty or loose cables
Look for loose or obviously faulty connections. If they appear to be OK, make
sure the connections are snug. If that does not correct the problem, try a different
cable.
Non-standard cables
Non-standard and miss-wired cables may cause numerous network collisions
and other network problem, and can seriously impair network performance. A
category-5 cable tester is a recommended tool for every 100Base-T network
installation.
RJ-45 ports:
use unshielded twisted-pair (UTP) or shield twisted-pair ( STP )
cable for RJ-45 connections: 100Ω Category 3, 4 or 5 cable for 10Mbps

connections or 100Ω Category 5 cable for 100Mbps connections. Also be sure
that the length of any twisted-pair connection does not exceed 100 meters (328
feet). Gigabit port should use Cat-5 or cat-5e cable for 1000Mbps connections.
The length does not exceed 100 meters.
Improper Network Topologies
It is important to make sure that user have a valid network topology. Common
topology faults include excessive cable length and too many repeaters (hubs)
between end nodes. In addition, user should make sure that network topology
contains no data path loops. Between any two ends nodes, there should be only
one active cabling path at any time. Data path loops will cause broadcast storms
that will severely impact network performance.
Diagnosing LED Indicators
The switch can be easily monitored through panel indicators to assist in
identifying problems, which describes common problems you may encounter and
where user can find possible solutions.
If the power indicator does turn on when the power cord is plugged in, user may
have a problem with power outlet, or power cord. However, if the switch powers
off after running for a while check for loose power connections, power losses or
surges at power outlet. If the problem still cannot be resolved, contact the local
dealer for assistance.
