Troubleshooting
This chapter describes how to troubleshoot your Series 5400zl Switches. Note
that this document describes troubleshooting mostly from a hardware
perspective. You can perform more in-depth troubleshooting using the soft-
ware 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 “Troubleshooting” in the Management and Configuration Guide,
which is on the ProCurve Web site at www.procurve.com. To display the list

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.
