Once you find a way to automatically restart the system, you still have to decide if you should.
Assuming you have a UPS.
Does the UPS trigger the system to shutdown, and if so after what percentage of battery life is used?
Does the system just continue to run until the battery is dead?
Does the UPS restore power to the system if the battery is less than xx% charged?
Do you know how many power failures you have per year, and how many of these exceed the battery life?
If you do decide to automatically restart the system, you should make sure that you wait until the power supply is stable.
There is no UPS.

NAME
upscode2 - Driver for UPScode II compatible UPS equipment
NOTE
This man page only documents the hardware-specific features of the upscode2 driver. For information about the core driver, see
nutupsdrv(8).
SUPPORTED HARDWARE
This driver supports UPS equipment which can be controlled via the UPScode II protocol. This is mainly Fiskars, Powerware equipment, but
also some (probably OEM'ed) products from Compaq.
EXTRA ARGUMENTS
This driver supports the following optional settings in the ups.conf(5):
manufacturer=value
Autodetection of this parameter is not possible yet (and it probably never will be). Therefore, this user-defined string accepts any
name. The default is unknown.
input_timeout=value
The timeout waiting for a response from the UPS. Some UPS models have shown to be rather slow, resulting in frequent messages about
empty responses from the UPS. If you see this, try increasing this value.
output_pace=value
Delay between characters sent to the UPS. This was added for completeness with the above parameter. It has not shown to be needed yet.
baudrate=value
The default baudrate is 1200, which is the standard for the UPScode II protocol.
full_update_timer=value
Number of seconds between collection of normative values.
use_crlf
Flag to set if commands towards to UPS need to be terminated with CR-LF, and not just CR.
use_pre_lf
Flag to set if commands towards to UPS need to be introduced with an LF. A Compaq T1500h is known to need this.
COMMANDS
The driver supports the following commands for those UPSen that support them. The available commands are autodetected during
initialization, so you should check availability with upscmd -l.
o test.panel.start - Start UPS self test
o test.battery.start - Start battery self test
o beeper.enable - Enable UPS beeper
o beeper.disable - Disable UPS beeper
o shutdown.return - Shut down in 1 second and wait for power to return
o shutdown.stayoff - Shut down in 1 seconds
o shutdown.reboot - Shut down in 1 seconds and reboot after 1 minute
o shutdown.reboot.graceful - Shut down in 20 seconds and reboot after 1 minute
NOTES
The Powerware UPS models that this driver has been tested against until now have not returned a value for battery.charge. Therefore, the
driver will guestimate a value based on the nominal battery min/max and the current battery voltage.
