Thecus Announces N5810PRO NAS with Built-in UPS
 

Many electronic devices, including network-attached storage (NAS), are not designed to have their power supply suddenly cut. Unforeseen circumstances that result in power outages can cause data loss that could set back your business operations significantly.

To prevent such events from occurring with the Thecus N5810PRO, a built-in mini-UPS (Uninterruptible Power Supply) has been included with the unit. The mini-UPS battery provides emergency power if the main power source where to fail. In the event of a power failure the mini-UPS will stand by for approximately 30 seconds (dependent on services in operation). If power is restored within this time frame, the NAS will continue at its normal state. If power has not been restored, the NAS will commence shut down of all operations.
