Hardware log in Open Manage for one of our T710 Servers reports periodic loss of communication with both power supplies. The duration of each incident ranges from 6 to 12 seconds. The frequency of incidents over the past 6 months appears to be random ranging from 1 to 24 days apart. Power Supply 1 has had 6 incidents of communication loss and Power Supply 2 had had 19 incidents. Below is a typical reported sequence in the log:
