Troubleshooting Tools
The tools available for troubleshooting on the switch are:
The LED indicators
These are located on the front panel of the switch. The LEDs indicate
the overall switch status, and the status of each of the switch's ports
and backplane segments (where applicable). See earlier in this man-
ual for a full description of the LEDs and their use.
SNMP
SNMP management in the switch is based on standard Management
Information Base (MIB) II and Private Enterprise MIB extensions.
You can configure the switch to send SNMP Traps to defined loca-
tions, thus allowing the possibility of performing limited trouble-
shooting from an SNMP Management Center.
Intel Device View
Intel Device View offers several features that can help your trouble-
shooting. These include: diagnostic messages, a log of system events,
a log of errors and a list of SNMP traps.

Troubleshooting Procedure

Isolating the Problem

If the switch has a problem, use the following procedure to isolate the
problem:
1 Check the LEDs.
The LEDs provide instant visual indication of the status of the
switch and the status of each ports.
2 Check the Diagnostics window.
The diagnostics tool automatically detects possible problems
and indicates possible causes and solutions. Use of this tool is
described in "Diagnostics Window", p. 37.
