Network master mode
A network UPS master is responsible for communicating with network UPS slaves on the same physical
network about critical power status. To set up your NAS with UPS as network master mode, plug in the
USB cable on the UPS to the NAS and follow the steps below:
1. Make sure the NAS is connected to the same physical network as the network UPS slaves.
2. Select the option “Enable UPS Support”.
3. Choose between whether the NAS will 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.
4. Click “Enable network UPS master”. This option appears only when your NAS is connected to the
UPS by a USB cable.
5. Enter the “IP address” of other network UPS slaves to be notified in the event of power failure.
6. Click “Apply” to confirm and continue the setup for the NAS systems which operate in network
slave mode below.
