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 8 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 8 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.
