Vertical Orientation; Horizontal Orientation - Control Data Corporation Finch 9410-4 Hardware Installation/Operation Manual

3.5 MOUNTING ORIENTATIONS
CAUTION
The drive should never be shipped or moved without the rotary-
arm shipping lock locked to prevent damage to the disk and/or
heads.
There are only two mounting orientations: disks in a horizontal plane and disks
in a vertical plane. In either the horizontal or vertical mounting. The uppermost
casting surface should be in a level position or drive performance may be affected.
3.5.1 VERTICAL ORIENTATION MOUNTING
In the vertical orientation, the drive must be mounted so that the heads are
above the spindle as shown in Figures 3-4 and 3-5. This is to ensure that the
read/write heads will return to the head landing area when power is removed.
Shock mounting in a vertical orientation is accomplished through the use of an
optional shock mount plate. The drive is mounted to the shock mount plate and
the shock mount plate to the cabinet. This configuration and mounting dimen-
sions are shown in Figures 3-4 and 3-5.
Two tapped holes are provided on each side of the drive for securing the drive
to the enclosure (cabinet). The drive may be bolted to an overhead member in
a suspended mount and/or bolted from below in a supportive mount (Figure 3-3).
Screws with 8-32 threads and sufficient length to allow several threads of engage-
ment in the casting after passing through the cabinet mounting member should be
used.
3.5.2 HORIZONTAL ORIENTATION MOUNTING
As shown in Figure 3-2, four 8-32 tapped holes are provided in the base of the
main deck casting to facilitiate mounting in the horizontal position.
The FINCH may be mounted with optional shock mounts or spacers directly to the
rack using 8-32 thread screws. If shock mounts or spacers are used, screw the
four mounts into their respective threaded holes as shown in Figure 3-6. Place
the drive in the rack or cabinet and secure it with screws with sufficient length
to ensure adequate thread engagement.
