Tandberg Data SDLT220-320 INTEGRATION, Manual

Page: 55 / 94

CHAPTER 4: Thermal Specifications
To evaluate different modes of operation, data was recorded either with data
compression enabled or disabled. Thermocouples were affixed to key board
components as shown in
Figure 4-2 . In addition, a thermocouple was placed within
the tape path enclosure to monitor the approximate temperature of the media, as
shown in
Figure 4-4 .
The results of the testing are listed in Table 4-1 and Table 4-2 below.

* The number in the Case Maximum Continuous Operating Temperature column are absolute limits that
should not be exceeded. In other words, expect physical component damage or failure if you exceed these
operating temperature limits by not providing adequate air flow through the drive.
