We used 825TQ-R720LPB + X9SRL-F-O, and now we have a slow flashing "I" (info led) on the front of the chassis, indicating a power supply problem. I checked IPMI and this also indicates a power supply problem. We already have changed both PWS (from a other server) but the issue stays the same.
Please update to IPMI V 1.87 or up, this solves the issue.
