Apc Ups Power System Error 02000 Link Here

Some APC Smart-UPS with network management cards (NMC) can experience firmware corruption causing spurious Error 02000. Connect via serial cable and use software to reflash firmware. Note: This only works if the UPS powers up for at least 30 seconds.

Secure the Load: If the system is unstable, move the load to a secondary power source or bypass immediately. apc ups power system error 02000 link
