Mounting Information
The disk drive can be mounted in any of the major mounting axes.
Safety/Regulatory Compliance
• When installing the HP C2244/45/46/47 Disk Drives 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 C2244/45/46/47 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.
