Designing a Liebert XD Solution

3.8 Liebert XDCF Placement
The Liebert XDCF is a self-contained module designed to cool Egenera’s BladeFrame EX cabinets and
equipment. Liebert XDCF modules attach to the rear of the Egenera BladeFrame EX cabinet, beside
the power modules (see Figure 17). No cutting or drilling is required to attach the modules; all
mounting holes, slots and pins required are fabricated at the factory. The Liebert XDCF does not
require electrical connections.
The number of Liebert XDCF modules required is determined by the heat load of the cabinet—cabi-
nets cannot share cooling from a Liebert XDCF module.
The Egenera BladeFrame EX cabinet has provisions for mounting two Liebert XDCF modules, should
the heat load require two modules. If only one Liebert XDCF will be needed, Liebert recommends
using the lower Liebert XDCF module.
The complete system consists of Liebert XDCF modules, piping, Liebert XDP or Liebert XDC refriger-
ant distribution units and those units’ chillers or drycoolers.
