To remove a drive backplane from the system, complete the steps in this procedure.

CAUTION: Hazardous moving parts nearby. (L008)
Procedure
1. Attach the electrostatic discharge (ESD) wrist strap.
The ESD wrist strap must be connected to an unpainted metal surface until the service procedure is
completed, and if applicable, until the service access cover is replaced.
Attention:
• Attach an electrostatic discharge (ESD) wrist strap to the front ESD jack, to the rear ESD jack,
or to an unpainted metal surface of your hardware to prevent the electrostatic discharge from
damaging your hardware.
• When you use an ESD wrist strap, follow all electrical safety procedures. An ESD wrist strap is
used for static control. It does not increase or decrease your risk of receiving electric shock
when using or working on electrical equipment.
• If you do not have an ESD wrist strap, just prior to removing the product from ESD packaging
and installing or replacing hardware, touch an unpainted metal surface of the system for a
minimum of 5 seconds. If at any point in this service process you move away from the
system, it is important to again discharge yourself by touching an unpainted metal surface for
at least 5 seconds before you continue with the service process.
2. Remove the fan cage assembly.
For instructions, see “Removing the fan cage assembly from the 9183-22X system” on page 20.
3. To remove the drive backplane, unplug but do not remove the front drives from their slots. Pull out the
drives far enough to prevent them from interfering with the removal of the drive backplane as shown in
the following figure.
