Figure 29 U2U Network Setup Diagram - Emerson Liebert Challenger 3000 User Manual

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 32).
NOTE
Only cooling units with large displays are supplied with a female-female coupler inside the
unit from the factory.
