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 15).
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.
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.
To connect multiple units in a U2U network, the Network IP address, U2U Group Number and the
U2U Address must be changed. The Network IP and the U2U Address must be unique on the net-
work.
NOTE
Only cooling units with large displays are supplied with a female-female coupler inside the
unit from the factory.
