Chapter 2 Installing and Cabling Enclosures 29
Use the following procedure and refer to Figure 2-1 to install each enclosure into
the rack.
When positioning an enclosure in the rack, do not block the air vents at the front or
back of the enclosure.
Caution – If you only have one person to perform the installation, remove the
power and cooling modules and drive modules from an enclosure before
installation, and use the optional nylon front support brackets. If possible, position
the enclosure on top of another device or shelf in the rack to hold the enclosure as
you attach the front brackets.
1. Considering your system configuration and weight distribution in the rack,
determine where you will install each enclosure in the rack.
2. Confirm that you have cables of adequate length to connect to hosts and to power
outlets.
3. (Square-cut European-style racks only) Insert the cage nuts in the corresponding
holes on the front and rear of the rack.
4. (Optional-one person installation) Screw the front support brackets into position on
the rack face using #10-32 x 5/8-inch screws (two per bracket).
These brackets enable one person to easily position and support the front of the
enclosure in the rack during installation.
5. Attach the side brackets to each side of the enclosure using #8-32 x 3/16-inch
flathead screws (four to eight on each side). The right and left side brackets are
identical.
Note – To allow adjustment of the brackets, do not tighten the screws completely
until the enclosure is mounted in the rack.
a. Use the alignment marks (Figure 2-2) stamped into the side brackets to position
the brackets and screws. The alignment marks show depth in inches.
Determine the depth you require and align the rear-most alignment mark on the
side bracket with the rear-most threaded holes on the enclosure. Make sure that
the alignment mark corresponding to the depth you want lines up with both the
top and bottom holes.
