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: 100Ω Category 3, 4 or 5 cable for 10Mbps connections or 100Ω

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.
