Troubleshooting 3-3
Table 3-5 Troubleshooting Improper Network Cabling and Topology
DESCRIPTION PROBLEMS AND 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 packet collisions
and cause other network problems that affect your network
performance. Refer to 2.4.3 Front Panel Connections 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 packet collisions 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.
