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 ).
