370 The Star Coupler board has been changed, added, removed, has experienced a checksum error, or is new
and the parameters for the device/board remain unchanged (typically frame 12 and 14 drives).
528 The power level in power unit 2 is not equal to the power level in power unit 1 after a microprocessor reset
(typically frame 12 and 14 drives).
561 The power level in power unit 2 is not equal to the power level in power unit 1 after a microprocessor reset
(typically frame 12 and 14 drives).
Subcode Description
