This section explains how you can use the system’s LEDs and e-buzzer to troubleshoot

system problems.

Troubleshooting with the System’s LEDs

There is a set of four LEDs located on the tower and rack-mount systems front bezel that

are used for diagnosing the health of the system. These LEDs warn of any impending

failures and allow you to take preventive action. For example, you may want to make a

system backup or replace a system component before it quits functioning. The remaining

four LEDs are the power, system, LAN, and locator LEDs. This section explains how the

system’s LEDs can be used for troubleshooting system problems and locating the system

you want to work on within a rack of systems.

Here is a list of the types of LEDs covered in this section:

• Power and System LEDs

• LAN LED

• Locator LED and Button
