General product information 2.4 Product/System Description Upper and lower modules may be mounted on the rear of the Egenera BladeFrame. Each module, when attached to a fully loaded BladeFrame EX rack, has a nominal cooling capacity of 10kW (2.8 tons; 34,000 BTUh). Performance is based on: • Entering fluid temperature—55°F (12.8°C) and • Dew point—50°F (10°C) or lower. The complete system consists of Liebert XDCF modules, piping and Liebert XDP or Liebert XDC (see Figure3 below. Figure 3 Lieb

Installation 4.0 INSTALLATION 4.1 References This document must be used together with site-specific documentation and documentation for other parts of the system. 4.2 Installation Considerations Liebert XDCF modules must be securely mounted to the rear of the Egenera BladeFrame cabinet. No cutting or drilling is required to attach the modules; all mounting holes, slots and pins required are fabricated at the factory. If only one Liebert XDCF will be attached to an Egenera BladeFrame cabinet,

Installation 4.3 Mounting Lower Liebert XDCF Module The lower Liebert XDCF module attaches to the Egenera BladeFrame cabinet with a mounting bracket, four bolts and a metal stud. Before the Liebert XDCF is mounted, the mounting bracket and a two-piece deflector panel must be attached to its top surface and insulation must be applied to the left side. 4.3.1 Preparing the Lower Module for Attachment 1. Position the mounting bracket over the two mounting holes. The holes are near the center of th

Installation 4.3.2 Attaching Lower Liebert XDCF Module Liebert XDCF modules mount on the rear of the Egenera BladeFrame cabinet, near the power mod- ules. The cabinet and Liebert XDCF have prefabricated mounting holes and studs to ease mounting. 1. Set the lower Liebert XDCF module on the left side of the ledge on the rear of the Egenera BladeFrame cabinet. Make sure the positioning stud on the bottom of the Liebert XDCF fits into the locator hole on the ledge as shown in Figure8. Figure 8 Loc

Installation Attaching Liebert XD Flex Pipe Support Panel Use of only the lower Liebert XDCF module requires attaching a Liebert XD Flex Pipe support panel and three pipe retainers. The retainers keep the refrigerant pipes behind the Egenera cabinet. If an upper Liebert XDCF module will be used, the Liebert XD Flex Pipe retainers will be attached to the upper module. To attach the Liebert XD Flex Pipe support panel: 1. Position the Liebert XDCF Liebert XD Flex Pipe support panel over the line
