4.5 USB Port
The Liebert APS contains a standard B type USB port on the rear of the unit to connect the UPS to a
network server or other computer for monitoring with any operating system, built-in UPS support or in
conjunction with Liebert MultiLink® software.
4.6 Liebert MultiLink®
Liebert MultiLink monitors the UPS continuously and can shut down configured computers in the event
of an extended power failure. Liebert MultiLink can configured to shut down the UPS and can also be
used without the USB cable when the Liebert IntelliSlot UNITY-DP SNMP Card is installed in the UPS. An
optional Liebert MultiLink License Kit permits shutting down the UPS over a network. For more
information about the Liebert IntelliSlot SNMP Card, Liebert IntelliSlot Web Card, and Liebert MultiLink
license kits, visit
www.VertivCo.com or contact your local Vertiv™ representative.
4.7 LCD Port
The LCD module contains the LCD port for power and data communication between the UPS monitor
module and display module. The LCD module can be removed from the Liebert APS and remotely located.
A longer Ethernet cable must be used when installing the LCD module remotely. A standard Ethernet
type cable (Category 5, with RJ-45 connectors, both ends meet T568B standard) can be used. Maximum
cable length is 14 meters to ensure proper communication signals between the UPS and the LCD module.
