transmit a Rack Power On command to the network. After youcomplete
concurrent repairs, use this function to restore power to expansion units
that are turned off or faulted off.
02 Fan Power Off
Use this function to select a concurrent fan power off operation. SPCN
responds by enabling subfunction range F0–F3 (see “F0-F3 Select Fan”) to
select the fan to be powered off.
03 Bulk Power Off
Use this function to select a concurrent bulk power off operation. SPCN
responds by enabling subfunction range B0–B5 (see “B0-B5 Select Bulk”) to
select the bulk to be powered off.
04 Fan Power On
Use this function to select a concurrent fan power on operation. SPCN
responds by enabling subfunction range F0–F3 (see “F0-F3 Select Fan”) to
select the fan to be powered on.
You only need this function if the wrong fan is powered off. The system
automatically starts a concurrently repaired fan after the fan is inserted.

Use this function to select a concurrent bulk power on operation. SPCN
responds by enabling subfunction range B0–B5 (see “B0-B5 Select Bulk”) to
select the bulk to be powered on.
You only need this function if the wrong bulk is powered off. The system
automatically starts a concurrently repaired bulk after the bulk is installed.
F0–F3 Select Fan
Use this subfunction to select the fan for the previously selected concurrent
repair operation. If accepted, SPCN performs the operation and disables
this subfunction range. The system displays a function 5 SRC when the fan
is turned off and removes it when the fan is installed.
B0–B5 Select Bulk
Use this subfunction to select the bulk for the previously selected
concurrent repair operation. If accepted, SPCN performs the operation and
disables this subfunction range. A function 5 SRC is displayed when the
bulk is turned off and removed when the bulk is installed.
Function 08–Fast Power Off: Function 08 is enabled only when you select Manual
mode.
Use this function when the system is suspended and you cannot perform a power
down.
Initially, the system displays an attention SRC, 11-x A1xx 8008. This SRC indicates
that you selected Function 08. To perform a fast power off, see “Powering Off and
Powering On the System” in the Problem Analysis information for your system.
Note: If the system password was changed at the most recent IPL, performing a
fast power off might cause that new password information to be lost.
