Wall-Mount Large Display
The Liebert CRV has a large display as standard equipment. Only large displays can be used for
remotely monitoring and controlling cooling units connected on the same network. Each wall-mount
large display requires 120V input power; Liebert provides an AC adapter wall plug. A straight-
through Ethernet cable must be connected between the network switch and the P64 port on the back
of the display. This will enable control and monitoring capabilities to any cooling unit connected to the
network.

All Liebert iCOM-controlled cooling units on a network must be set to run in the same teamwork
mode.
