4.Troubleshooting
This section is intended to help you solve the most common problems on
the Micro-Switch/24
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 this 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 that 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 end nodes, there should be only one active cabling path at
any given time. Data path loops will cause broadcast storms that will
severely impact your network performance.
