(16)Redundant power supply module information
*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.

• Turns ON when one or more redundant power
supply modules with input power OFF are detected.
• Turns on if any of SD1780 bits is on.
• Turns off if all bits of SD1780 are off.
• Turns OFF when the main base unit is not the

ON : Momentary power
failure detected
• Turns ON when a momentary power failure of the
input power supply to the power supply 1 or 2 is
detected one or more times. After turning ON,
remains ON even if the power supply recovers from
the momentary power failure.
• Turns OFF the flag (SM1782, SM1783) of the power
supply 1/2 when the CPU module starts.
• When the input power to one of the redundant power
supply modules turns OFF the corresponding flag
turns OFF.
• Turns OFF when the main base unit is not the
redundant main base unit (Q38RB).
