Figure 30 Wiring A Small Display For Stand-Alone Operation - Emerson Liebert Challenger 3000 User Manual

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.
