Troubleshooting
This chapter describes how to troubleshoot your 8200 zl switch. Note that this
document describes troubleshooting mostly from a hardware perspective.
You can perform more in-depth troubleshooting using the software tools
available with the switch, including the full-featured console interface, the
built-in web browser interface, and ProCurve Manager, the SNMP-based
network management tool. For more information, see the chapter “Trouble-
shooting” in the Management and Configuration Guide, which is on the HP
networking Web site at www.hp.com/networking/support.
This chapter describes the following:

Basic Troubleshooting Tips
Most problems are caused by the following situations. Check for these items
first when starting your troubleshooting:
■ 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
network collisions and other network problems, and can seriously impair
network performance. Use a new correctly-wired cable or compare your
cable to the cable in appendix B, “Switch Ports and Network Cables” for
pinouts and correct cable wiring. A category 5 cable tester is a recom-
mended tool for every 100Base-TX and 1000Base-T network installation.
