Dell PowerEdge UPS 500T User Manual page 24


Shutdown type
o Hibernate (default option)
If available with your operating system, is better to use the hibernation feature (first
available with Windows 2000) as there are a number of advantages. If the system is
shut down, all work in progress and system information are automatically saved to
the disk. The computer itself is also de‐energized. When mains power returns, all the
applications re‐open exactly as they were and the user placed back in their work
environment.
Hibernate function must first have been activated in the operating system. In the
power options on the Windows control panel, check that hibernate option is
activated on the Hibernate tab sheet.
Note: If you select hibernate, but your computer does not have this function, Power
Protector will still protect the installation by carrying out the normal (default)
shutdown.
Note: For Windows Vista, please refer to the FAQ section of this manual.
o Shutdown
This option shuts down your applications and the system, but does not de‐energize
the computer. The system offers the user the choice to de‐energize the computer, in
which case it is the UPS that cuts power.
On most computers, this configuration is necessary if you want the server to restart
as soon as mains power returns.
o Power‐off
This option shuts down your applications and the system, and de‐energizes the
computer. This configuration is advised if you wish to be on hand when the system
re‐starts. (or for load shedding)
o Script
This option manages the shutdown in a custom script that you can create to fit with
your own shutdown sequence.
You can integrate the standard Windows shutdown command (more info with
shutdown /? in a Windows Command Line interpreter).
Shutdown script: the absolute path of the script.

Outlet shutoff Active
Using this option, Dell UPS Local Node Manager will send a delayed shutoff command to the
outlet. This delayed command is sent to the UPS at the beginning of the shutdown sequence,
and this is the point of no return for this sequence. The outlet is turned off at the end of the
shutdown sequence.

Shutdown sequence trigger
When a power utility failure occurs, the shutdown sequence is started as soon as the first of
the two following condition is reached.
o After the Shutdown timer (if configured).
o When NMC or UPS shutdown criteria is reached (UPS / NMC Card Decision according
to many criteria see next figure)
