Troubleshooting

This section is intended to help solve the most common problems on the PoE Injector Managed Switch.

Incorrect connections

The switch port can automatically 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 correctly pinned 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: 100 Category 3, 4 or 5 cable for 10Mbps connections, 100

Category 5 cable for 100Mbps connections, or 100 Category 5e/above cable for

1000Mbps connections. Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet).
