Chapter 5: Troubleshooting
This section is intended to help user to solve the most common problems on the
Ether-GSH2404W 24x10/100/1000TX plus 4 Mini-GBIC Web Managed Switch.
5.1 Incorrect connections
The switch port can auto detect straight or crossover cable when the switch link 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.
RJ-45 ports: use unshielded twisted-pair (UTP) or shield twisted-pair ( STP ) cable for
RJ-45 connections: 100
Ω
Category 3, 4 or 5 cable for 10Mbps connections or 100
Ω
Category 5 cable for 100Mbps connections. Also be sure that the length of any
twisted-pair connection does not exceed 100 meters (328 feet). Gigabit port should
use Cat-5 or cat-5e cable for 1000Mbps connections. The length does not exceed 100
meters.
