Due to an overlapping bitmap entry, DD9800 Revision2 may indict an SP due to "Voltage is Faulty" , when the real issue is a CPU External IERR.
When both events ( CPU External IERR & "Voltage is faulty") occur simultaneously, it is safe to ignore the voltage alert, and focus troubleshooting on why the CPU encountered
a CPU IERR. For more details on troubleshooting CPU IERR errors on DD9800 platforms, please contact your Support provider for assistance.
- DD9800 Rev 2
- DDOS 5.7.x / 6.0.x / <126.96.36.199

This issue is found in DDOS versions 5.7 , 6.0, & 6.1
The root cause is SP fault bitmap is overlapped, so when IERR event happens , the warning message incorrectly displays "voltage is faulty"
#define APL_FRU_FAULT_SP_CPUMISC (1 << 17)
This overlapping bitmap will be fixed in DDOS 6.1.3.x
