These temperature limits are extremely important and must not be exceeded at the worst case
drive and system operating conditions with the drive randomly seeking, reading, and writing.
Note:
Measured between top and bottom of disk enclosure. See Figure 3 on back page for location of
measurement points.
COOLING
This drive does require airflow in order to fulfill its' reliability performance.
Please refer to Environmental section of the 0663 Disk Drive product specification for full details
of the maximum allowable temperatures and measurement points.
Integration into using System
The drive's mounting frame is electrically isolated from the drive's disk enclosure.
NOTE: THE DISK ENCLOSURE IS NOT AT GROUND POTENTIAL.
Any user mounting scheme must not result in the disk enclosure being shorted to ground. Drive
malfunction will result if this occurs.
COMPATIBILITY
Testing should be carried out to ensure that the drive is fully compatible with the using
system.
System BIOS, Operating system, Device drivers and interface card BIOS/ characteristics can
effect the ability to attach the drive to the system. All need to be verified jointly as compatible
with the drive.
