Replace the control panel with power off

You might need to replace the control panel in the server. Use the procedure in this section to perform this task.

These procedures describe the replacement of the control panel with power off for the server models listed in Model 285,515,520,525,550, and 720 control panels.

If your system is managed by the Hardware Management Console (HMC), use the HMC to complete the steps for replacing a control panel. For instructions, see Replace a part using the Hardware Management Console.

To replace the control panel with the power off, complete the following procedure:

Perform the prerequisite tasks described in Before you begin.
Remove the control panel with power off. Refer to Remove the control panel with power off.
Attention: A control panel or control panel filler must be in place when the system power is on for proper air flow and cooling. Refer to Model 520, 550, 570, and OpenPower® 720 control panel fillers for instructions on removing a control panel filler.
If necessary, remove the new control panel from its packaging. If there are control-panel overlays included with the new control panel, install the appropriate overlay on the control panel.
Note: Remove the machine type label, with the serial number, from the front of the existing control panel and place the label on the new control panel.
Connect the control-panel signal cable B to the back of the control panel C.
Carefully slide the control panel into the control panel bay until you feel the locking tabs A lock in place.

Install the front cover onto your system. Refer to Install the front cover from the model 520, 550, or OpenPower 720, or the 0595 expansion unit.
If you replaced the control panel as part of another procedure, return to that procedure now. If you replaced it because it was not operational, verify that the new resource is functional. Refer to Verify the installed part.
Start the system. Refer to Start the system or logical partition.
Note: If there is a ball or dot that appears in the middle of the control panel, toggle between function 02 and function 01 until the graphic disappears.
