Attention: If the operator panel cable is disconnected, settings for passwords, date
and time, as well as service processor call-in functions will be lost. These settings can
be reset after the cable is replaced.
1. Power off the system (see “Powering Off and Powering On the System” on
page 492).
2. Disconnect the ac power cords from both the system rack and the I/O rack
Note: If your system’s I/O rack contains drawers that are shared by another
system, disconnect the ac power cords from the rear of the I/O drawers that
are attached to this system only.
3. Remove the front cover to access the operator panel (see “Covers” on page 494).
4. Pivot the operator panel outward from the system rack by loosening the two
retaining screws.
5. Loosen the retaining screws on the connector for the operator panel cable and
disconnect the cable.
6. Loosen the retaining screws on the connector for the other end of the operator
panel cable from the back of the primary I/O drawer and remove the cable.
Replacement
1. Replace the operator-panel cable by reversing the steps in the removal procedure.
2. Power on the system (see “Powering Off and Powering On the System” on
page 492).
