3.Network Application
This section provides you a few examples of network topology in which the palm
Switch 500 is used, the Switch is design to be used as a desktop or segment
switch.
The switch automatically learns node address, which are subsequently used to
lter and forward all traf c based on the destination address.
•Stand Alone
The Palm Switch 500 is designed to be a compact desktop size switch,
which is an ideal solution for small workgroup. The Switch can be used as
a standalone switch to which personal computers, server, printer server are
directly connected to form small workgroup.

•Enlarge Your Network
You can use Uplink port of the Palm Switch 500 to connect with another
hub or switch to interconnect each of your small switched workgroup to
form a large switched network.
You can connect anyone switch port to hub or switch without crossover
cable by the Auto MDI/MDI-X function.
In the below illustration, two Switches are used to interconnect two small
workgroup. All the devices in this network can communicate with each
other. Connecting servers to the Switch allow other users to access the
server’s data.

4. Trouble Shooting
The Palm Switch 500 can be easily monitored through panel indicators to assist in
identifying problems. This section describes common problems you may encounter
and where you can nd possible solutions.
•Diagnosing LED Indicators
If Link indicator does not light up after making a connection, you may
check whether network interface (e.g., a network adapter card on the
attached device), network cable, or switch port is defective or not. Be
sure the cable is plugged into both the Switch and corresponding device.
Veri ed the proper cable type is used and its length does not exceed
speci ed limits.
•Power
If the power indicator does not turn on when the power cord is plugged
in, you 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
connection, power loses or surges at power outlet. If you still cannot
resolve the problem, contact your local dealer for assistance.
•Cabling
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 ).
