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 6-11.

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.
