3. Troubleshooting
This section is intended to help you solve the most common problems on the S8TB 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 mis-wired cables may cause numerous network collisions and other network problem, and can
seriously impair network performance. A category 5-cable tester is a recommended tool for every 100Base-TX
network installation.
RJ-45 ports: Use unshielded twisted-pair (UTP) or shield twisted-pair (STP) cable for RJ-45 connections: 100Ω
Category 3, 4 or 5 cable for 10Mbps connections or 100Ω Category 5 cable for 100Mbps connections.
Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet).
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 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, which describe common problems you may
encounter, to assist in identifying problems and where you can find possible solutions. See the section “LED
Indicators” on page 5 above.
Labeling
After performing the troubleshooting steps above, and before contacting Tech Support, check the product and
packaging labels for information to provide Tech Support.
