Setting this variable to firmwareUpdate(2) causes the UPS to begin a firmware update if possible.

Reading this variable will return noFirmwareUpdate(1) when the UPS firmware has not been updated (or previous results have been cleared), updateInProcess(3) when the UPS firmware is being updated, updateSuccessful(4) when the UPS firmware has been successfully updated, or updateFailed(5) if the UPS firmware update failed.
