These features are implemented for a single server (BSU) by connecting the
server’s serial port to the UPS computer interface port and installing the
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.
! The System Administrator installs PowerChute ® Plus software on each
protected server and uses the graphical user interface to set up the
operational parameters required by site policies.
Figure 5-8 illustrates the connections between the UPS, master server, and
additional protected servers.
