Choosing a Troubleshooting Procedure
Use Table 10 to determine which troubleshooting procedure you should use. For a
description of the status LEDs and their meanings, see "Status and Activity LEDs"
on page 4.
Symptom and LED State
All of the LEDs are off.
The ERR LED or the DIAG are on.
None of the devices connected to the
switch can communicate, the ERR
LED is off, and the PWR LED is on.
A single device connected to a
Token-Ring port is having trouble
communicating.
A single device connected to a Fast
Ethernet port is having trouble
communicating.
Note: Segment refers to a single cable or interconnected cables
between a switch port and the device at the other end.
Table 10. Symptom, LED State and Recommended Procedure
Procedure A
Use this procedure if all of the LEDs are off:
1. Verify that the power cord is connected at both ends and that the power outlet is
working.
2. If the power cord is connected correctly, the outlet is working, and the problem
persists, the problem is in the switch. In that case, contact technical support as
described in Chapter 6, "Getting in Touch with Technical Support".
Procedure B
Use this procedure if the ERR LED is on:
1. Verify that the power to the internal power supply is on. If the power is off (and
the switch is powered only by the redundant power supply), apply power to the
internal power supply. If the ERR LED turns off after this, resume using the
switch, otherwise proceed to step 2 below.
