Servicing the Motherboard Assembly
This section describes how to service the motherboard assembly.
The motherboard assembly is a replaceable component that requires you to power off the
server before servicing. The motherboard includes a Power Distribution Board (PDB) in the
assembly. 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
motherboard. You must disconnect the power cables before performing these
procedures.
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.

Use the Oracle ILOM backup utility prior to removing the motherboard. This utility
