■ Rack Safety and Precautions
WARNING:
Possible personal injury:
• Lifting hazard: The library weighs 63.5 kg (140 lb) plus the weight of
the drives. With all of the drives and power supplies installed, the
weight is 122.5 kg (270 lb). Use at least two people and a mechanical
device to lift and position the library. Make sure you read the
information in “Lifting Techniques” on page xx before beginning.
• Also consider the library’s total weight when you are placing other
equipment into the rack. To prevent an unbalanced situation, install
the heaviest equipment on the bottom and the lightest equipment on
the top. Failure to do so might cause the rack to become unstable
and tip over.
Observe the following safety precautions when you are installing the library into a rack:
• If the rack has front or rear doors, do not allow the doors to interfere with the
library’s ventilation. The rack’s internal ambient temperature should not exceed the
recommended operating temperature range of the library. The maximum rack air
ambient temperature is 40°C (104°F).
• Ensure that rack doors provide adequate clearance to the library.
• Ensure that the combination of the library with other equipment in the rack does not
create an overcurrent condition, whether the equipment is connected directly to the
branch circuit or to a power distribution strip.
• 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 library relies on the ground pin of the power cord for its earth ground.
