Known Issues

The showenvironment command shows that power supply unit (PSU) load current fluctuates (BugID 6282974). Additionally, fault status for the PSU load current is not consistent with the current: Sometimes the same current displays status as "OK" and other times as "Fault".

This is caused by the pulse nature of the fan control. The load current reading depends on at which moment in pulse cycle it is initiated.



Note - You can safely the load current and its fault status readings. These will be removed in the next firmware revision.



In the following example showenvironment PS0 PS1 was run several times in a few seconds.
