Start of Troubleshooting Process

If one or more devices (such as PCs) connected to a switch are unable to
communicate with other devices in the network, use the following steps to start the
troubleshooting process:
1. Locate the switch to which the device is connected. Use the network sketch, the
label on the cable connected to the device, or other network records to help you
locate the switch.
2. If you have set up a console session (see Chapter 4, "Switch Access"), it can be
used to determine whether diagnostics have been completed correctly. A list of
normal diagnostic messages is shown on page 39.
3. Observe the LEDs on the switch front panel. Figure 2 on page 2 illustrates the
LEDs. For explanations of the LEDs, see section "Status and Activity LEDs"
on page 4. Review this section before proceeding with the troubleshooting
process.
4. Use Table 10 below to locate the symptom that best describes the
communication problem and the LED pattern you observed. Then, go to the
section that contains the recommended actions for resolving the problem and
follow that procedure.
