Troubleshooting

This chapter describes how to troubleshoot your 5400zl switches. 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

ProCurve Web site at
