INTRODUCTION.
2-2.
This section contains information on unpacking
and incoming inspection, input power requirements,
mounting, checkout, and packing and shipping for the disc
drive.
2-3.
UNPACKING AND INSPECTION.
2-4.
If
the carton is damaged upon receipt, request that
the carrier's agent be present when the unit is unpacked.
Inspect the unit for damage (scratches, dents, broken parts,
etc).
If
the unit is damaged and fails to meet specifications,
notify the carrier and the nearest HP Sales and Service
Office immediately. (HP Sales and Service Offices are listed
at the back of this manual.) Retain the shipping container
and the packing material for the carrier's inspection.
Hewlett-Packard will arrange for repair or replacement of
the damaged unit without waiting for any claims against the
carrier to be settled.

POWER REQUIREMENTS.
2-6.
The disc drive may be operated continuously from
primary power sources of 100, 120, 200, 220, or 240 Vac
±10%, single phase, 50/60 Hz. Prior to installing the disc
drive, determine the primary power voltage, remove the
bottom cover of the disc drive, and ensure that power
supply strapping of TB1 is compatible with primary power
voltage. Figure 2-1 shows the strapping of TB1 for various
voltages.

POWER CABLE.
2-8.
To protect operating personnel, the National
Electrical Manufacturers Association (NEMA) recommends
that the unit panel and chassis be grounded. This unit is
equipped with a three-conductor power cable which
grounds the unit.
2-9.
MOUNTING.
2-10.
Prior to rack mounting, remove the top cover in an
environmentally clean area and remove the shipping clamp
shown in figure 5-7. The shipping clamp is used to prevent
internal movement that would cause damage to the heads
or disc components during packaging or shipment. When
removing the shipping clamp, use care not to bump or jar
the heads or snag the head leads. The shipping clamp is
secured in place by a pozi-drive screw. After loosening the
pozi-drive screw, rotate the shipping clamp out of the way
and re-tighten the pozi-drive screw. Replace the top cover.
INSTALLATION
III
Note:
Retain the shipping clamp in the manner
described
above, to use
for future
shipping.
2-11.
The unit is air cooled. Sufficient space (a one-inch
minimum) should be allotted so that a free flow of air can
be exhausted from the rear of the unit when it is in
operation. The unit should be used in an area where the
ambient temperature does not exceed 40°C. The air inlet is
the screen at the lower front of the disc drive; the inlet
. must not be covered.
2-12.
Mounting the disc drive in a rack cabinet requires
that the rack mounting technique maintains isolation be-
tween the disc drive chassis and the rack cabinet. Disc drive
front frame design maintains isolation between the disc
drive front panel and the chassis. The HP 13211A option
001 Disc Drive Rack Mounting Kit is an available accessory
for mounting the disc drive in an HP 29400 Series Cabinet
with the required chassis isolation. The following procedure
provides rack mounting instructions using the HP 13211A
option 001 Disc Drive Rack Mounting Kit (figure 2-4
includes identification of the isolation technique). To
mount the disc drive in an HP 29400 Series Cabinet using
the HP 13211A option 001 Disc Drive Rack Mounting Kit,
proceed as follows:
a. Place the disc drive on a table in an environmentally
clean area. Attach the right and left chassis slides to the
disc drive using eight number 8-32, 0.625-inch flat head
screws, four on each side, as shown in figure 2-3.
b. Attach the rack mount brackets to the rack cabinet
using eight number 1/4-20, 0.5-inch hexagon head
screws with eight number 1/4 split lock washers and
eight number 1/4-20 spring nuts as shown in figure 2-4.
Before securing to rack cabinet, ensure that the
mounting brackets are level from the front to the rear.
Note:
Align the mounting screw in conjunction
with RETMA mounting pattern shown in
figure 2-4. Proper alignment with the
RETMA pattern will assure alignment of
the disc drive chassis mounting holes with
the RETMA pattern holes used for secur-
ing the disc drive front panel to the
cabinet.
A minimum vertical clearance of 10-1/4
inches above the bottom front of the rack
mount bracket must be maintained· to
allow for disc drive clearance.
