Hardware Description
This section mainly describes the hardware of the 4 10/100/1000TX + 1
Mini-GBIC Switch, and gives a physical and functional overview on certain
switch.
Physical dimension
The 4 10/100/1000TX + 1 Mini-GBIC Switch physical dimension is 165 x 100 x
32.5 mm (L x W x H).
Front Panel
The Front Panel of the 4 10/100/1000TX + 1 Mini-GBIC Switch consists of LED
Indicators and a reset button. Please refer to the LED Indicator section for LED
description.
Reset button: it provides an easy way for user to reset the configuration
back to the default settings. Press the button more than 5 seconds, and then
the switch will restart and set all configurations back to the default settings.
Rear Panel
The rear panel consist the 4 10/100/1000Base-TX RJ-45 port, one Mini GBIC slot
and DC Power Jack as shown in figure. The switch will work with DC in the range
of 12V/0.8A.

The Rear Panel of 4 10/100/1000TX + 1 Mini-GBIC Switch
RJ-45 Ports (Auto MDI/MDIX): 4x 10/100/1000 N-way auto-sensing for
10Base-T, 100Base-TX or 1000Base-T connections.
In general, MDI means connecting to another Hub or Switch while MDIX
means connecting to a workstation or PC. Therefore, Auto MDI/MDIX
would allow connecting to another Switch or workstation without changing
non-crossover or crossover cabling.
Mini GBIC slot: The MINI GBIC module is optional, and with 3.3V supported.
There is one LED indicator for Mini GBIC port – LNK/ACT.

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 Feet
A. Make sure mounting surface on the bottom of the switch is grease and dust
free.
B. Remove adhesive backing from your Rubber Pads.
C. Apply the Rubber Feet to each corner on the bottom of the switch. These
footpads can prevent the switch from shock/vibration.
Power On
Connect the power adaptor to the power jag on the rear panel of the switch. The
other side of power adaptor connects to the power outlet. The external power
supply in the switch works with DC power in 12V/0.8A. Please check with the
power indicator on the front panel to see if power is properly supplied.

Network Application
This section provides user a few samples of network topology in witch the switch
is used. In general, the 4 10/100/1000TX + 1 Mini-GBIC Switch is designed as a
segment switch. That is, with its address table (8000 MAC address) and high
performance, it is ideal for interconnecting networking segments.
PC, workstations, and servers can communicate each other by directly
connecting with 4 10/100/1000TX + 1 Mini-GBIC 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. The distance
between two switches via fiber cable depends on the type of fiber transceiver.
Small Workgroup
The 4 10/100/1000TX + 1 Mini-GBIC Switch can be used as a standalone switch
to which personal computers, server, printer server, are directly connected to
form small workgroup.
Segment Bridge
For enterprise networks where large data broadcasts are constantly processed,
this switch is an ideal solution for department users to connect to the corporate
backbone.

8
Two 4 10/100/1000TX + 1 Mini-GBIC Switches with PCs, print server, and local
server attached, are both connected to the core switch. All the devices in this
network can communicate with each other through the 4 10/100/1000TX + 1
Mini-GBIC Switch. Connecting servers to the 4 10/100/1000TX + 1 Mini-GBIC
Switch allows users accessing the data on server. By using fiber ports to connect
switches, the distance between two switches depends on the type of fiber
transceiver.

Troubleshooting
This section is intended to help user to solve the most common problems on the4
10/100/1000TX + 1 Mini-GBIC 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: 100ΩCategory 3, 4 or 5 cable for 10Mbps

10
connections or 100ΩCategory 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.
