11.3 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 92).
