6. Troubleshooting
This section is intended to help you solve the most common problems
with installation of the FM2008/2009 switch.
Incorrect connections
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 miswired cables may cause numerous
network collisions and other network problems, 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 at any time. Data path
loops will cause broadcast storms that will severely impact your
network performance.
