2.7.4.  UPS 
A UPS can provide backup power to your NAS in the event of a power outage. Using a UPS 
can protect your data and NAS from sudden shutdown or service interruptions.  
  Network UPS: Here you can setup your NAS to be the network UPS server (Master 
mode) and set its IP address, when the UPS’s USB cable is connected to your NAS.  
Other devices that are in the same local area network will be then set to slave mode. 
In the event of a power outage, the master and slave devices will immediately detect 
this stoppage in power and then determine whether or not to commence shutdown 
procedures based on the time period that has been set.
