Enable Wake On Select this to be able to turn on the NAS through its wired Ethernet connection.
LAN
You must have a computer or router on your LAN that supports sending Wake On LAN "magic
packets" to turn on the NAS.
To use Wake On LAN from a computer on your LAN, install a program such as Wake On LAN EX
or another Wake On LAN program that supports sending magic packets.
You can use Wake On LAN from a remote location if the router in front of the NAS supports
sending magic packets.
Use the NAS's power button or the User > Restart/Shutdown menu in the upper right corner of
the Web Configurator screen to turn off the NAS.
Minimum UPS When you use an APC Uninterruptible Power Supply (UPS) with a USB connection to the NAS,
Capacity the NAS shuts itself down if the APC UPS's battery charge gets down to the percentage you
specify in this field. This allows the NAS to shut down properly and avoid data loss caused by a
power failure when the UPS stops supplying power.
A setting around 50% is recommended. A setting close to 100% is not recommended since it
would cause the NAS to shut down whenever the UPS is charging. A setting close to 0 is also not
recommended since the UPS would not have enough power to allow the NAS to shutdown
properly.
Power On After Select an option to set whether or not the NAS restarts when the power is restored after a
Power Failure power failure.
