Three or more units with small disp

Three or more units with small displays: To network three or more cooling units, each equipped with a small display, connect a straight-through CAT5 Ethernet cable from the P64 connector on each cooling unit’s Liebert iCOM input/output board to a common network switch (see Figure 26).
Large Displays
A network switch is required to enable Ethernet communication on one or more cooling units with large displays. Each cooling unit with a large display 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 female-female coupler provided with the unit. Con- nect the red crossover cable, which is provided with the cooling unit, between the coupler and the P64 port on the back of the large display (see Figure 28).

NOTE
Only cooling units with large displays are supplied with a female-female coupler inside the unit from the factory.

Wall-Mount Large Display
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. See 6.0 - Mounting a Large Display on a Wall for mounting details and Figure 31 for wall-mount dimensions.
Combining Large and Small Displays on a U2U Network
Setting up a network of cooling units equipped with large and small displays requires a network switch. The controls are to be connected to the switch as described above.
