Planet WGSW-2840 [92/104] Incorrect connections

5. TROUBLE SHOOTING

This section is intended to help you solve the most common problems on the WGSW-2840/WGSW-5240 ethernet

Switch.

5.1 Incorrect connections

The switch port can auto detect straight or crossover cable when you link switch with other Ethernet device. For

the RJ-45 connector should use correct UTP or STP cable, 10/100Mbps port use 2 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.

5.1.1 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.

5.1.2 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.

5.1.3 Improper Network Topologies

It is important to make sure that you have a valid network topology. Common topology faults include excessive

cable length and too many repeaters (hubs) between end nodes. In addition, you should make sure that your

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 your network

performance.

5.2 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 you can find possible solutions.

IF the power indicator does 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 connections,

power losses or surges at power outlet. IF you still cannot resolve the problem, contact your local dealer for

assistance.
