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, if the female-to-female
coupler is provided with the unit. Connect 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 81). If the
female-to-female coupler is not provided, connect the straight-through cable to Port P64 on the large
display.
