Troubleshooting the Switch
Read this chapter to learn about basic troubleshooting of the switch. The tasks in
this chapter are independent, unless otherwise noted, and are listed in no
particular order.
We strongly recommend that you download the Cisco Configuration Assistant
from Cisco.com and use the enhanced set of tools to troubleshoot the switch and
your network. You can download it from this Cisco.com site:

Before You Begin
The troubleshooting features described in this chapter are available if the switch
has an IP address. Make sure that the switch has been set up as described in
Chapter 2, "Setting Up the Switch."
Familiarize yourself with the monitoring features (see
Switch") from which you can find out the specific problems on the switch and
from which you can prevent problems by addressing problematic trends.
Before you upgrade the switch, review the information in the Release Notes for
the Catalyst Express 520 Switches on Cisco.com.
