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:
