Shutdown Sequence; Load Segments - Dell PowerEdge UPS 500T User Manual

Shutdown Sequence

At the end of the shutdown procedure, when all servers have been shut down, the UPS itself may shut
down to avoid unnecessary discharge of its batteries, depending on its configuration. See Figure 48 for
the shutdown sequence.

Load Segments

Some UPS models are equipped with load segments. Load segments are sets of receptacles that can be
controlled through the Dell Network Management Card, providing an orderly shutdown and startup of
your equipment. Load segments are dependent on the UPS's Inverter. Shutdown of the Inverter causes
shutdown of the load segments (usually two load segments). Refer to the UPS user's guide for the
location of the load segments.
