3.1 Improper Network Cabling and Topology

Improper network cabling or topology setup is a common cause of poor network performance or even network failure.

Figure 13 Troubleshooting Improper Network Cabling and Topology

PROBLEM

CORRECTIVE ACTION

Faulty cables

Using faulty network cables may affect data rates and have an impact on your

 

network performance. Replace with new standard network cables.

 

 

Non-standard

Non-standard cables may increase the number of network collisions and cause other

network cables

network problems that affect your network performance. Refer to Section 2.2.2 on

 

page 14 for more information on network cable types.

 

 

Cabling Length

If you use longer cables than are needed, transmission quality may be affected.

 

The network cables should not be longer than the limit of 100 meters.

 

 

Too many hubs

Too many hubs (or repeaters) between the connected computers in the network

A loop in the

A data path loop forms when there is more than one path or route between two

data path

networked computers. This results in broadcast storms that will severely affect your

 

network performance. Make sure there are no loops in your network topology.
