Wiring a Liebert iCOM U2U Network

A network switch is required to enable Ethernet unit-to-unit communication on one or more Liebert
CRV's. Each Liebert CRV requires two straight-through Ethernet cables from a network switch. One
cable connects to port P64 on the Liebert iCOM input/output board and the other straight-through
cable connects to the P64 port on the back of the large display (see Figure 117).

Wall-Mount Large Display
The Liebert CRV has a large display as standard equipment. Only large displays may 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.
