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 Intelligent Management Center (HP

IMC), the SNMP-based network management tool. For more information, see

the chapter “Troubleshooting” in the Management and Configuration Guide

for your switch, which is on the HP Networking web site at www.hp.com/
