PowerChute
®
plus software on the server (BSU) .
The System Administrator uses the PowerChute
®
plus graphical user interface to
set up the operational parameters required by site policies.
Additional servers installed in the same rack may be connected to the UPS
when:
!
You install the Smart Slot™ UPS Interface Expander Unit into the UPS.
!
You connect the protected server’s serial port to the expander accessory
unit using the simple signaling cables received with the Expander Unit
Interface Kit.

Plus software on each
protected server and uses the graphical user interface to set up the
operational parameters required by site policies.
