Troubleshooting
This section is intended to help you solve the most common prob-
lems on the MIL-S2400S 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 problem, and can
seriously impair network performance. Acategory 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. You should make sure that your network topolo-
gy contains no data path loops. Between any two-end
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.
Diagnosing LED Indicators
The switch can be easily monitored through panel indicators to assist
in identifying problems, which describes common problems you may
encounter and where you can find possible solutions.
If the power indicator does not turn on when the power cord is
plugged in, you may have a problem with power cord. Check for
loose power connections, power losses or surges at power outlet. If
you still cannot resolve the problem, contact your local dealer for
assistance.
