Servicing the Disk Backplane
This section describes how to service the 4-Drive backplane and 12-Drive backplane.
The disk backplane (DBP) is a replaceable component that requires you to power off the
server before servicing. Perform the 4-Drive backplane or 12-Drive backplane procedures.
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.
