UPS 
 
By enabling UPS (Uninterruptible Power Supply) support, you can protect your NAS from 
abnormal system shutdown caused by power disruption. There are two options provided on 
the UPS page for the NAS during a power failure: 1) turn off the server after the AC power 
fails, or 2) enter the auto-protection mode after the AC power fails. For option 1, the NAS will 
shut itself down after the specified time. For option 2, the NAS will stop all running services 
and unmount all volumes to protect your data after the specified time. For details on NAS 
behavior during a power failure, refer to the Behavior of the UPS Feature of the NAS section. 
Please note that to protect your data, once the power outage starts, the NAS will 
automatically turn itself off or enter auto-protection mode (depending on your settings) after 
30 seconds regardless of the specified time for either of the above options if the remaining 
UPS battery charge is < 15%. 
 
In this chapter, the following topics are covered: 
USB Modes 
o Standalone Mode – USB 
o Standalone Mode – SNMP 
o Network Master Mode 
o Network Slave Mode 
Behavior of the UPS Feature of the NAS 
 
USB Modes 
 
Standalone Mode – USB 
To operate under USB standalone mode, follow the steps below: 
1. Plug in the USB cable on the UPS to the NAS. 
2. Choose between whether the NAS will shut down or enter auto-protection mode after the 
AC power fails. Specify the time in minutes that the NAS should wait before executing the 
option you have selected. After the NAS enters auto-protection mode, the NAS resumes 
the previous operation status when the power restores. 
3. Click Apply All to confirm. 
 
Standalone Mode – SNMP 
To operate under SNMP standalone mode, follow the steps below: 
1. Make sure the NAS is connected to the same physical network as the SNMP-based UPS. 
2. Enter the IP address of the SNMP-based UPS.   
						

							155 
 
3. Choose between whether the NAS should shut down or enter auto-protection mode after 
the AC power fails. Specify the time in minutes that the NAS should wait before executing 
the option you have selected. After the NAS enters auto-protection mode, the NAS 
resumes the previous operation status when the power restores. 
4. Click Apply All to confirm. 
 
Network Master Mode 
A network UPS master is responsible for communicating with network UPS slaves on the 
same physical network regarding critical power status. To set your NAS with UPS as network 
master mode, plug in the USB cable on the UPS to the NAS and follow these steps: 
1. Make sure the NAS (the UPS master) is connected to the same physical network as the 
network UPS slaves. 
2. Click Enable network UPS Support. This option only appears when your NAS is 
connected to the UPS by a USB cable. 
3. Choose between whether the NAS should shut down or enter auto-protection mode after 
the AC power fails. Specify the time in minutes that the NAS should wait before 
executing the option you have selected. After the NAS enters auto-protection mode, the 
NAS resumes the previous operation status when the power restores. 
4. Enter the IP address of other network UPS slaves to be notified in the event of power 
failure. 
5. Click Apply All to confirm and continue the setup for the NAS systems which operate in 
network slave mode below. 
 
Network Slave Mode 
A network UPS slave communicates with network UPS master to receive the UPS status. To 
set up your NAS with UPS as network slave mode, follow these steps: 
1. Make sure the NAS is connected to the same physical network as the network UPS 
master. 
2. Select Network UPS slave from the Protocol drop down menu. 
3. Enter the IP address of the network UPS server. 
4. Choose between whether the NAS should shut down or enter auto-protection mode after 
AC power fails. Specify the time in minutes that the NAS should wait before executing 
the option you have selected. After the NAS enters auto-protection mode, the NAS 
resumes the previous operation status when the power restores. 
5. Click Apply All to confirm. 
 
Note: To allow the UPS device to send SNMP alerts to the NAS in the event of power loss, 
you may have to enter the NAS IP address in the UPS configuration page.

Behavior of the UPS Feature of the NAS 
 
There are three phases during a power outage: 
Phase 1: Power loss starts until the end of the waiting time. 
Phase 2: From the end of the waiting time to the point when the UPS device runs out of 
its battery. 
Phase 3: After the UPS device runs out of its battery and until the power restores. 
 
Phase 1:  
As soon as the power loss starts, the NAS will detect the UPS device’s battery. If the 
remaining UPS battery charge is < 15%, the system will automatically turn itself off or enter 
auto-protection mode (depending on your settings) after 30 seconds regardless the time you 
specified for either of the settings (turn off the NAS or enter auto protection mode.) If the 
UPS battery charge is > 15%, the NAS will wait for the specified time you entered in the 
UPS page.  
 
If the power resumes during this phase, the NAS will remain in operation.  
 
Phase 2: 
Depending on your setting on the UPS page: 
If in auto-protection mode, the NAS will stop all running services and unmount all 
volumes. The NAS at this moment will become inaccessible.  
If the NAS is powered off, it will remain off.  
 
If the power resumes during this phase: 
If in auto-protection mode, the NAS will reboot and resume its previous state.  
If the NAS is powered off, it will remain off.  
   
Phase 3: 
Depending on your setting on the UPS page: 
If in auto-protection mode, the NAS will lose its power and shut down.  
If the NAS is powered off, it will remain off.  
 
After the power resumes during this phase, the NAS will react according to your settings in 
System Settings > Power Recovery.
