Removing and replacing the control panel in the 7063-CR2
Learn how to remove and replace the control panel in the IBM Power Systems HMC (7063-CR2) system.
Removing the control panel from the 7063-CR2 system
To remove the control panel from the IBM Power Systems HMC (7063-CR2) system, complete the steps in
this procedure.
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. Power off the system.
For instructions, see “Stopping the 7063-CR2 system” on page 99.
3. Place the system in the service position on an ESD surface on a table.
For instructions, see “Placing a 7063-CR2 system into the service position” on page 101.
