• 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.
4. Remove the service access cover.
For instructions, see “Removing the service access cover from a 7063-CR2 system” on page 104.
5. Remove the control panel cable.
a) Label where the control panel cable (A) connects to the power distribution board and to the control
panel.
b) Remove the control panel cable from the power distribution board and from the control panel.
Use your thumb or finger to press the release latch on the connector to remove the cable. Unclip
the cable from the right air baffle.

Replacing the control panel cable in the 7063-CR2 system
To replace the control panel cable in the IBM Power Systems HMC (7063-CR2) system, complete the
steps in this procedure.
Procedure
1. Ensure that you have the electrostatic discharge (ESD) wrist strap on and that the ESD clip is plugged
into a ground jack or connected to an unpainted metal surface. If not, do so now.
2. Replace the control panel cable.
a) Using your labels, replace the control panel cable (A) into the power distribution board and into the
control panel.
Ensure that the cable latch clip snaps into place on the connector.
b) Route the cable through the right air baffle channel; the USB cable nests inside the control panel
cable.
Clip the cable into the right air baffle.
