6 Functional Specifications
Air Flow Requirements
Adequate air flow must be provided in the enclosure for the tape drive to dissipate heat resulting from approximately 15.0 watts of power consumption. The air flow around the entire tape drive must be sufficient to prevent the tape path temperature from exceeding 40° C (104° F). However, air flow within the enclosure must be minimal at the tape path. Otherwise, particulate contamination of the media can result.
Particulate Contamination Limits
The ambient operating environment should not exceed the particulate counts shown in Table

Figure 6-4 shows the particulate contamination profile of a typical office compared to the specifications for the tape drive. Contamination profiles of individual office areas vary.
