• Use care when you insert the system backplane so that no damage occurs to the components at
the socket edge of the backplane.
• Ensure that the system backplane is fully seated and is all the way into the system.
• You must remove and replace the system backplane at a flat angle. The ventilation holes in the
top cover can come into contact with the DIMMs in the system backplane if the insertion of the
backplane is at an angle or is rushed. As a result of possible contact, DIMMs can be scratched and
can leave residue on the top cover.
Figure 130. Replacing the system backplane
c) Simultaneously rotate the two levers on each side of the system backplane in to secure the system
backplane to the system.
d) Tighten the two screws on the sides of the system backplane.
e) Using your labels, replace the signal cables into the rear of the system.
7. Using your labels, reconnect the cables at the rear of the system unit.
8. Using your labels, replace the two power cords at the rear of the system.
For instructions, see “Connecting the power cords to a 7063-CR2 system” on page 101.
Removing and replacing covers on a 7063-CR2 system
Learn how to remove and replace the covers on an IBM Power Systems HMC (7063-CR2) system so that
you can access the hardware parts or service the system.
Removing the service access cover from a 7063-CR2 system
To remove the service access cover from an IBM Power Systems HMC (7063-CR2) system, complete the
steps in this procedure.
About this task
Attention: For safety, airflow purposes and thermal performance, the service access cover must
be installed and fully seated before you power on the system.
Procedure
1. If the system is not already powered off and in the service position, complete these steps: “Placing
a 7063-CR2 system into the service position” on page 101
2. 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.
