A problem with output overload has been reported by the uninterruptible power supply 2145 UPS. The Mode Indicator on the 2145 UPS front panel is illuminated red.
Ensure that only one or two 2145s are receiving power from the 2145 UPS. Also ensure that no other devices are connected to the 2145 UPS.
Disconnect the 2145-4F2s from the 2145 UPS. If the Mode Indicator is now green on the disconnected 2145 UPS, reconnect the 2145-4F2s one at a time to determine which one causes the overload. Then, on the 2145-4F2 which caused the problem, in the sequence shown, exchange the FRUs for new FRUs. See "Possible Cause-FRUs or other" after the last action in this section.
If the Mode Indicator is still red with all outputs disconnected, replace the 2145 UPS electronics assembly. If the Mode Indicator is still red, replace the 2145 UPS assembly.
