8. Troubleshooting This section is intended to help you solve some common problems encountered
while using the MIL-SM2401M switch series.
Incorrect connections
The switch auto-detects the polarity and direction of the UTP cable attached. If no
link I seen, then check the following:
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
different cables.
Non-standard cables
Non-standard and miswired cables may cause numerous network collisions
and other network problems. This can seriously impair network performance.
A category 5 cable tester is a recommended tool for every 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 or
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.
