DESCRIPTION

 

 

Minimum UPS

When you use an APC Uninterruptible Power Supply (UPS) with a USB

 

 

Capacity

connection to the NSA, the NSA shuts itself down if the APC UPS’s

 

 

 

battery charge gets down to the percentage you specify in this field. This

 

 

 

allows the NSA 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 NSA 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 NSA to shutdown

 

 

 

properly.

 

 

 

 

 

 

Power On After

Select an option to set whether or not the NSA restarts when the power

 

 

Power Failure

is restored after a power failure.

 

 

 

 

 

 

Keep Former

Select this option to have the NSA automatically restart only if it was

 

 

Status

operating when the power failed. The NSA remains off if it was already

 

 

 

off when the power failed.

 

 

 

 

 

 

Always Power

Select this option to keep the NSA operating as much of the time as

 

 

On

possible. The NSA restarts automatically even if it was turned off when

 

 

 

the power failed.

 

 

 

 

 

 

Always Power

Select this option to keep the NSA from automatically restarting when

 

 

Off

the power is restored after a power failure. This is a computer’s

 

 

 

“traditional” behavior. Select this if you have other servers such as a

 

 

 

domain controller or DNS server that you want to start or check after a

 

 

 

power failure before the NSA turns on.

 

 

 

 

 

 

Power On/Off Schedule

 

 

 

 

 

 

Enable Power

Select this option to have the NSA turn itself off and on or reboot

 

 

Control

schedules.

 

 

 

Refer to Section 15.3.1 on page 326 for this screen.

 

 

 

 

 

 

Enable Wake

Enable Wake On LAN to be able to turn on the NSA through its wired

 

 

On LAN

Ethernet connection.

 

 

 

You must have a computer or router on your LAN that supports sending

 

 

 

Wake On LAN “magic packets” to turn on the NSA.

 

 

 

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 NSA supports sending magic packets.

 

 

 

Use the NSA’s power button or the Web Configurator’s Maintenance >

 

 

 

Shutdown menu to turn off the NSA.
