Px4-300d shuts down/powers off while on UPS battery, regardless of remaining battery level

Question

Upon line power failure, the UPS is instantly available to supply power to the px4-300d.  The UPS is adequately sized to provide well over an hour of runtime during a power failure.  The only way to have caching operate is to have a UPS connected.  With the UPS connected, the NAS sees the UPS, the current power condition, and an accurate battery power level (%).  Once the power fails, the unit begins its shutdown process and completes gracefully, even though the remaining power in the UPS battery is still near 100%.  The whole point of having UPS backup is to keep the device running for as long as possible during a power failure, and then to gracefully shut-down the device should the UPS battery level reach a critical level and line-power still not restored.  This is MANDATORY to be addressed in the next firmware release, or provide access to a configuration file that specifies the battery level percentage which triggers a shutdown.  Why choose this "Enterprise Quality" storage solution if during a power outage it shuts itself down while everything else is still operating?  Makes absolutely no sense.

Hi easy-e,
What is the firmware version on your device currently?
LifeLine-based network storage devices should remain up and running normally using only UPS battery power until the UPS reports remaining battery is less than 3 minutes or below 5%. At his point, device shutdown will be triggered and your network storage device will gracefully shut down.
Have you checked to make sure it is compatible?:
What Universal Power Supply (UPS) models are compatible with my ix or px network device?
APC UPS not working with network storage device
If it is not shutting down properly, I would suggest contacting technical support to see if they can troubleshoot the cause of this problem.
