Troubleshooting
This section is intended to help solve the most common problems on the 24 10/100TX
plus 2 Mini-GBIC/Copper managed PoE switch.
Incorrect connections
The switch port can automatically detect straight or crossover cable when the user
links the switch with other Ethernet device. For the RJ-45 connector should use correct
UTP or STP cable, 10/100Mbps ports use 2 pairs twisted cable. If the RJ-45 connector
is not correctly pinned on right position, 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 shielded twisted-pair (STP)
cable for RJ-45 connections: 100Ω Category 3, 4 or 5 cable for 10Mbps
connections, 100Ω Category 5 cable for 100Mbps connections, or 100Ω
Category 5e/6 cable for 1000Mbps connections. Also be sure that the length of
any twisted-pair connection does not exceed 100 meters (328 feet).
