UPS "Configuration Fault in Memory" Error Displays
Issue
After shutting down the Uninterruptible power supply (UPS) unit and turning it on again the
Uninterruptible power supply displays the following error message:
Configuration fault in memory
This message may also be displayed after a power outage when the Uninterruptible power
supply (UPS) is turned back on again.
During the shutdown process of the UPS, the batteries may have been disconnected from the
UPS prior to it fully shutting down.
The UPS is operating normally.
Solution
In order to clear the error message the batteries including any Extended Battery Module (EBM)
of the UPS have to remain connected to the UPS and the UPS unit needs to be completely
powered down until it reaches the all blank Liquid-crystal display (LCD) state. Wait some
additional three (3) minutes and then power the UPS unit up again.
This is necessary because during the shutdown sequence, the configuration parameters are
saved into a nonvolatile Random-access memory (RAM) location so that they will be
permanently remembered for the next startup.
If the battery is disconnected before the save of this information is complete the error message
Configuration fault in memory
will be displayed during the next power up of the UPS unit. This is because an unexpected
checksum error has been detected by the UPS unit.
