6. Troubleshooting

This section is intended to help you solve the most common problems on the

TEG-S2620is.

This section is intended to help you solve the most common problems on the

TEG-S2620is.

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 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.

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
