Load Segments - IBM Network Management Card User Manual

Table 38. Shutdown criteria
Criterion
Backup time before shutdown starts (using the Shutdown
parameter)
Shutdown when the battery level is low (using the
Shutdown If Capacity Under parameter)
Shutdown when backup time is less than specified (using
the Shutdown If Remaining Time Under parameter)

Load segments

Some UPS models are equipped with load segments. Load segments are sets of
receptacles that can be controlled through the network management card, providing
an orderly shutdown and startup of your equipment. Load segments are dependent
on the main output of the UPS. Shutdown of the main output causes shutdown of
the load segments. For the locations of the load segments, see the Installation and
Maintenance Guide that comes with the UPS.

Network Management Card : User's Guide
Description
When the UPS switches to battery power, the network
management card starts the shutdown timer countdown
and starts the system shutdown sequence at the end of
the countdown. You must select this value carefully to
allow users time to complete their tasks and disconnect,
without exceeding battery backup time.
Note: The IBM UPS Manager software uses parameters
that can interfere with this shutdown configuration. If you
use this criterion to initiate a shutdown sequence, an
automatic restart when power is restored is not
guaranteed. For more information, see the documentation
that comes with the IBM UPS Manager software.
When the network management card detects that the
remaining backup time percentage is less than the
configured level, the shutdown sequence is started. The
default is 20%.
Note: The UPS has an equivalent parameter. The
network management card does not accept values less
than what is configured in the UPS. See the UPS
documentation.
When the network management card detects that the
percentage of remaining backup time is less than the set
value, the shutdown sequence is started.
