Table 23. Function 06 Disable CPM (continued)

Function / value		Action or description
06	_ _ _ D _ _	Use the Increment or Decrement buttons to display option D
		(Disable).
06	_ _ _ _ 0 0	Press Enter to perform the Disable CPM operation. With the 00
		displayed the operation was successful (the SPCN interface is
		operational and the Disable message will be sent). At the next IPL,
		CPM is automatically available. If FF appears instead of 00,
		function 06 failed due to an SPCN communications error.

Function 07–Restore System Power and Perform Concurrent Maintenance Repair: Function 07 is available only on systems with SPCN and only when the system is powered on and in Manual mode. Function 07 allows you to restore power to frames that had a power failure or were powered off. It is also used for concurrent maintenance repair on bulks and fans.

When you first enter function 07, the control panel enters subfunction mode by displaying (**). Increment and decrement functions scroll to selectable values. If an SPCN communications error is present when you select a subfunction, the subfunction does not start, and FF (processing failed) displays in the rightmost display positions. Entry of a valid subfunction when no SPCN communications errors are present results in a 00 (processing successful) displayed in the rightmost display positions. Pressing Enter when ** is displayed results in exiting subfunction mode. For example:

**Cancel Request

The system returns this subfunction when you select ** for subfunction and activate enter. Use this to cancel a pending subfunction 2–5 concurrent maintenance operation. SPCN responds with an EPF 1–5 (enable panel subfunction) to clear any other subfunction range enabled previously.
