Momentary power
SM1783 failure detection flag
for power supply 2 *1
*1: The "power supply 1" indicates the redundant power supply module (Q64RP) mounted on the POWER 1 slot of the redundant base unit (Q38RB/Q68RB/
Q65WRB).
The "power supply 2" indicates the redundant power supply module (Q64RP) mounted on the POWER 2 slot of the redundant base unit (Q38RB/Q68RB/
Q65WRB).
*2: The module whose first 5 digits of serial No. is 04012 or later.
However, for the multiple CPU system configuration, this applies to all CPU modules whose first 5 digits of serial No. are 07032 or later.
