Chapter 6
Maintenance and Troubleshooting
This Chapter
If you are familiar with networking and switch operations, you may be able to
diagnose and solve some problems yourself.
This chapter gives tips on how to:
■ start your switch (see “How the Switch Starts Up” on page 74).
■ avoid problems (see “How to Avoid Problems” on page 75).
■ reconfigure your switch if you accidentally clear the FLASH memory (see
“What to Do if You Clear FLASH Memory Completely” on page 77).
■ reset passwords if they are lost (see “What to Do if Passwords are Lost” on
page 78).
■ gather information from your switch that support personnel need to
provide accurate support tailored to your situation (see “Getting the Most
Out of Technical Support” on page 78).
■ restart the switch at any time with no configuration (see “Resetting Switch
Defaults” on page 79).
■ check whether there is a connection between the switch and another
routing interface in the network (see “Checking Connections Using PING” on
page 79).
■ troubleshoot problems with DHCP IP addresses if the switch is acting as a
client or as a server (see “Troubleshooting DHCP IP Addresses” on page 81)
■ examine the route that packets pass between two systems running the IP
protocol (see “Using Trace Route for IP Traffic” on page 81).
Information gained from the LEDs on the front panel of the switch is described
in the AT-8700XL Series Hardware Reference.
