PAC2000S12-B1 PSU
●
The communication of the standby PSU is faulty.
●
The active PSU MV12/SV12 experiences a fault, such as input power failure, input undervoltage,
input overvoltage, output overvoltage, output overcurrent, overtemperature, fan fault, and
output undervoltage (the output voltage is lower than 11.8 V), which causes the Smart_ON#
signal to be at low level.
●
Both the PSON12V# and INSTALLED# signals are becomes high level from low level.
●
The load power is greater than the upper power limit in cold standby mode.
The active PSU exits from cold standby mode if any of the following conditions is met:
●
The system sends the D0h 0x00 command.
●
The MCU of the active PSU restarts.
●
The communication of the active PSU is faulty.
