Mounting
Information
The disk drive can be mounted in any of
the
major
mounting axes.
Safety /Regulatory
Compliance
• When installing an HP C2486A/88A/90A Disk Drive into
an
end
use
product, safety
and
regulatory Conditions of Acceptability must be considered. Contact your sales/service
representative for a-copy of
the
Hewlett-Packard Conditions
of
Acceptability.
•
If
the
front bezel option has been installed,
it
should be evaluated in
the
intended end use
application.
•
If
installing an HP C2486A/88A/90A Disk Drive with an
adaptor
mounting frame,
the
complete installation should be evaluated in
the
intended end use application.
Chassis
Dimensions
and
Mounting
Screw
Locations
The
physical dimensions and mounting screw locations for each interface option are shown in
the
respective appendices for each option.
The
length dimensions shown are for
the
chassis
only and do not include clearances for power and interface connectors.
Physical
Mounting
There are twelve (12) threaded mounting holes (for no. 6-32 screws) on
the
disk
drive: four on
each side, and four on the
bottom
(see Figure 2-3).
Use
the mounting guidelines listed in
the
respective appendices for each option.
Airflow
Requirements
The
disk drive must be installed
so
that
the
ambient air temperature surrounding
the
disk
drive is maintained within
the
limits specified under Environmental Requirements in
Chapter
1.
Airflow
is
required to maintain disk drive performance and reliability. For best results,
the
drive should be operated as cool as possible.
The
airflow requirements for each interface
option are listed in Table 1-4.
The
majority of
the
air should
flow
across
the
PCA. This is a
function
of
the
specific airflow
pattern
inside
the
cabinet where
the
disk drive is installed.
The
airflow
pattern
around
the
drive should be adjusted to prevent
the
temperature
measuring points on
the
HDA and
the
PCA
from exceeding
the
maximum limits shown
in
the
respective appendix for each interface option.
All temperature measurements should be made under worst case operating conditions, These
conditions should be maintained for
at
least one hour
to
allow
the
drive
to
reach equilibrium
before making any measurements.
