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 10 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

network

cables

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

cause other 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

between the

computers in

the network

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

network may increase the number of network collision or other network

problems. Remove unnecessary hubs from the network.

A loop in the

data path

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

between two networked computers. This results in broadcast storms that

will severely affect your network performance. Make sure there are no

loops in your network topology.
