To install the filer after the rack adapter rails are installed inside the rack, perform the
following steps:
1. Using two or more persons, lift the filer into position at the front of the rack.
2. With one person on each side of the cabinet to support it, lower the filer onto the
rack adapter rails.
3. Slide the filer into its mounting position with the front mounting brackets flush
against the vertical rails.
4. With the front mounting brackets aligned with the holes on the left and right ver-
tical rails, use a #2 Phillips screwdriver to tighten the thumbscrew on each side.
5. Using a torque wrench with a #2 Phillips bit, torque each screw to 27 inch-pounds
(3.0 newton-meters).

The half-U filler panel provides the proper spacing between the installed filer and
other equipment installed in the rack, such as the PowerVault 700N storage system or
a tape backup device. Mounting hardware for the filler panel consists of two 10-32 x
0.625-inch screws and two 10-32 cage nuts.
Perform the following steps to install the cage nuts and install the filler panel:
1. Locate the filler panel and position it in the rack, above and flush against the top of
the filer. See if the holes align with the mounting holes in the vertical rails. Invert
the filler panel, if necessary, for optimum fastener hole alignment. Make a note of
the mounting holes in the vertical rail in which you must install the cage nuts.
By installing the filler panel one way or the other (inverted), you can achieve the
proper fit, whether the filer occupies whole-unit or half-unit rack positions.
2. Insert the lower lip of the cage nut over the bottom of the opening in the back of
a vertical rail as shown in Figure 2-5. Then insert the small end of the cage-nut
installation tool (provided in the rack mounting kit) through the opening in the rail
(from the front), and hook the tool over the top lip of the cage nut.
3. Push in on the cage nut while rotating the tool up and pulling the tool back toward
you until the top lip of the cage nut snaps into position.
4. Repeat this process to install the other cage nut on the opposite side of the verti-
cal rail.
