3.0 XDF C
OMPONENTS
3.1 Standard Components—Self-Contained, Air Cooled and Water/Glycol Cooled
Models
3.1.1 Frame
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.
3.1.2 Enclosure
The XDF is equipped with seals to maintain a separate air volume inside the equipment compart-
ment.
3.1.3 Doors
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 Plexiglas
™
window for viewing installed equipment. The rear door is solid, full-height sheet metal.
3.1.4 Side 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.
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.
