Troubleshooting
Basic Troubleshooting Tips

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 seri-
ously impair network performance. Use a new correctly-wired cable or
compare your cable to the cables in appendix B, "Cables and Connectors"
for pinouts and correct cable wiring. A category 5 cable tester is a
recommended tool for every 100Base-T network installation.
Improper Network Topologies. It is important to make sure you have
a valid network topology. Common topology faults include excessive
cable length and excessive repeater delays between end nodes. If you have
network problems after recent changes to the network, change back to
the previous topology. If you no longer experience the problems, the new
topology is probably at fault. Refer to the Network Design Guide for
topology configuration guidelines. This guide can be found online at the
HP World Wide Web site for networking products, http://www.hp.com/go/

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.
If you wish to build redundant paths between important nodes in your
network to provide some fault tolerance, you should enable Spanning
Tree Protocol support on the switch. This ensures that only one of the
redundant paths is active at any time, thus avoiding data path loops.
Spanning Tree can be enabled through the switch console, the web
browser interface, or HP TopTools for Hubs & Switches.
