Purpose
FWA-6520/5020 contains AMI code based BMC , the status of "PSU presence detected" may confuse customer due to the display.
Target Audience
For anyone who needs to check the status of the PSU on the FWA-6520/FWA-5020 series.
Minimum requirement
- FWA-6520/FWA-5020 series
- System BMC can retrieve PSU state properly
- Meanings from discrete readings in following
working PSU = discrete 0x0080
AC lost PSU = discrete 0x0880
Not Presence = discrete 0x0180
Failure detected = discrete 0x0280
Failure Voltage detected = discrete 0x0a80
Steps
<1> Both PSU serving normally
