Rack Safety and Precautions
WARNING:
Possible personal injury:
• Lifting hazard: The library weighs 44.45 kg (98 lb) plus the weight of
the drives. 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 xviii 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.

Fiber-optic Safety
WARNING:
Eye hazard. Never look directly into a fiber-optic cable, a fiber-optic
connector, or a laser transceiver module. Hazardous conditions might
exist from laser power levels that are capable of causing injury to the
eye.
Be especially careful when using optical instruments with this
equipment. Such instruments might increase the likelihood of eye injury.
The laser transceivers in fiber-optic equipment can pose dangers to personal safety.
Ensure that anyone who works with this Sun StorageTek equipment understands these
dangers and follows safety procedures. Ensure that the optical ports of every laser
transceiver module are terminated with an optical connector, a dust plug, or a cover.
