15 Replace the Front LED Indicator Module

This section describes how to service the front LED indicator module.

The front LED indicator module is a replaceable component that requires you to power off the server before servicing. For more information about replaceable components, see Illustrated Parts Breakdown and Replaceable Components.

Caution:

Ensure that all power is removed from the server before removing or installing the disk backplane. You must disconnect the power cables before performing this procedure.

Caution:

These procedures require that you handle components that are sensitive to electrostatic discharge. This sensitivity can cause the component to fail. To avoid damage, ensure that you follow electrostatic discharge safety measures and antistatic practices. See Electrostatic Discharge Safety.
