Features of
the Interface
Expander
The Interface Expander:
• Mounts in all
APC
devices equipped with a SmartSlot
accessory slot.
• Works well in a heterogeneous network. Servers run-
ning different operating systems can monitor the
same
UPS
simultaneously.
• Supports advanced or simple signaling on the
advanced port of the
UPS
.
• Can delay shutdown of the
UPS
until all servers have
shut down gracefully.
• Allows you to restart hung servers.
• Has operating modes that cause the
UPS
to shut down
after confirmation from all protected devices or after
an interval set by the user. See “Configuring the
Interface Expander” on page 19.
• Does not depend on the operation of the network to
protect connected devices. As a hard-wired acces-
sory, the Interface Expander reliably conveys impor-
tant status messages during poor power conditions.
