Rack Safety and Precautions

WARNING:
Possible personal injury:
•The dual drive 9840R weighs 22.7 kg (50 lb) and the 9840S weighs
18.6 kg (41 lb) with tray slides. To install the unit into a rack or
remove the unit from a rack might require more than one person.
•When you slide a drive unit out of the rack, you shift the rack’s center
of gravity. Ensure the rack is stable enough to withstand this shift.
Observe the following safety precautions when you install 9840R or 9840S trays
in the StorageTek RACK001:
•Do not allow rack elements to interfere with the tape drive’s ventilation.
The rack’s internal ambient temperature should not exceed the
recommended operating temperature range of the 9840Rxx/9840Sxx.
•Ensure that the combination of the 9840Rxx/9840Sxx with other
equipment in the rack does not create an overcurrent condition in the
power source. The combination of equipment in the rack must not
exceed the rating plate amperage of the power distribution strip and/or
the rated amperage of the facility’s branch circuit.
•Ensure that all equipment in the rack has reliable earth ground, whether
the equipment is connected directly to the branch circuit or to a power
distribution strip.
Note: The 9840R and 9840S rely on the ground pin of the power cord
for their earth ground.
