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

GSW-2453. 

 

 

The switch port can auto detect straight or crossover cable when you link switch with 

other Ethernet device. For the UTP 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 UTP 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 contains no data 

path loops. Between any two ends nodes, there should be only one active cabling path
