Remove
8 screws which attach the shipping frame to the disk chassis and
11ft
the
unit free
of
the frame.
(6)
With the right and left chassis slides extended fully forward, slide the disk drive
chassis between the inner members until the front slide mounting hole pattern
lines
up
with the tapped holes in the chassis. Thread three 8-32 X %-inch button-
head
screws through the slide
and
into the chassis. Perform this on each side of
the chassis.
(7)
Slide the unit through the cabinet to the rear and thread two additional 8-32 X
1/.t_
Inch button-head screws through the slide and into the chassis
on
each side.
(8) Locate the chassis in the closed position
in
the cabinet. Adjust each slide bracket
height by loosening the
slide bracket screws to obtain the 5.97 mm (0.235-inch)
dimensions
as
shown
in
Drawing No. 103587.
(9)
Reinstall the bezel.
(10)
Install the slide restraining blocks (Part No. 102776) at the rear
of
the cabinet
using the hardware provided. Adjust the restraining blocks to prevent the
intermediate slide member from working
to
the rear during normal operation.
(11)
For top load models only, install the brim (Part No. 102691) using the hardware
provided.
(12)
Install the catch assem blies
as
shown in Figure
2-2
using the hardware provided.
Adjust the catch spring
on
the EIA rail
so
the ball stud assembly installed on the
bezel strikes the catch spring on the
EIA
rail squarely. Apply a small amount
of
lubricant
(PERTEC
Part No.
~04,
or equivalent) to each ball stud.

show the relationship of the rail mounting brackets to a
standard EtA cabinet and should
be
referred to in conjunction with the following
procedure.
Prior to installation
of
the disk mounting slides, determine the exact location in the
cabinet in which the disk drive is to
be
mounted.
NOTE
To
ensure correct hole spacing positions for the slide
mounting bracket, catch assemblies, and top load brim
assembly, the location
of
the bottom surface
of
the bezel
must
lie between a pair
of
rail holes spaced V2-inch apart.
(1)
Thread and tighten three 10-32 X 3/B-inch button-head Phillips screws for each
pair
of
front
and
rear brackets into the
EtA
rails; spacing must
be
as
shown
in
Figure 2-8.
(2)
Place a star lockwasher and 10-32 nut on each of the three screws. The nuts
should
be
started onto the screw only far enough to hold. The mounting bracket
will
be
secured between the back of the EIA mounting surface and the lockwasher.
NOTE
If
the cabinet rails have untapped mounting holes, the
nut
bars furnished in the hardware
kit
are
to be used in place
of
the 10-32 nuts.
(3)
Install the right and left brackets to the rails and tighten the 10-32 nuts sufficiently
to hold them in place.
(4) Determine that the bracket surface adjacent to the rail is parallel to the rail and to
the side of the cabinet.
