Troubleshooting
This chapter describes how to troubleshoot your switch. This document describes troubleshooting mostly from a hardware perspective. You can perform more in-depth troubleshooting on the switch using the software tools available with the switch, including the full-featured console interface, the built-in web browser interface, and HP 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 ProCurve Web site at www.procurve.com/manuals. You may want to bookmark
