Designing a Liebert XD Solution

3.6 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 14). 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—

cabinets 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

refrigerant distribution units and those units’ chillers or drycoolers.
