indicator color.
The DC_OK
LED shall light green if the DC output is within specification, and should be off if the output falls out of specification.
The AC_OK
LED is Green if the AC is within specification and off when out of specification. Note: With 5 V standby, Green also indicates
that PSU is in standby mode/output off.
