3.0XDF COMPONENTS

3.1Standard Components—Self-Contained, Air Cooled and Water/Glycol Cooled Models

3.1.1Frame

The self-contained, air cooled XDF is 82-1/4 inches (2089mm) tall; the water/glycol cooled unit, 79-3/4 (2026) tall. The self-contained, air cooled XDF has 36U (63 inches) of usable rack height. The water/glycol cooled XDF has 42U (73-1/2 inches) of usable rack height. Both the self-contained, air cooled and water/glycol cooled XDF units have a standard EIA rack width of 19 inches (483mm).

The XDF frame consists of heavy-duty, riveted, 12-gauge steel. The unit has fixed front rails and adjustable rear rails with square holes for installing rack-mount equipment. The front and rear verti- cal frame members accommodate internal mounting rail options and provide space to route and man- age cabling.

Cutouts in the top (front and rear) permit customer cable entry (Figure 6). All units have casters, stabilizing feet and a grounding lug.

3.1.2Enclosure

The XDF is equipped with seals to maintain a separate air volume inside the equipment compart- ment.

NOTE

Preventing air infiltration into the XDF will significantly improve overall performance and reduce the amount of condensate generated. Ensure that all cable entrances are sealed and that doors are closed securely. Check to ensure that all panels are properly installed; this is especially important if panels have been removed in the field.

3.1.3Doors

The front and rear doors are framed from sheet metal and are removable. A multi-point latch with key lock is provided for security. The front door may be either solid sheet metal or have a Plexiglaswindow for viewing installed equipment. The rear door is solid, full-height sheet metal.

3.1.4Side Panels

Side panels are constructed of sheet metal and use special fasteners to permit removal for mainte- nance. Insulation is included to provide improved thermal and sound insulation, as well as to prevent condensate formation on the outside of the unit.
