Safety Guidelines
•Ensure that cables from other equipment do no t obstruct the airflow through
the chassis or impair access to the power supplies or cards. Route cables away
from field-replaceable components to avoid disconnecting cables
unnecessarily for equipment maintenance or up grades.
Stabilizing the System
Observe the following general precautions to stabilize the system:
•Install any stabilizers that came with your equipment rack before mounting
or servicing the system in the rack.
•Load the rack from the bottom to the top, with the heaviest system at the
bottom.
•Do not stack the system on top of any other equipment. If the system falls, it
can cause severe bodily injury and damage the equipment.
•If you are using an equipment shelf, ensure that the shelf is constructed to
support the weight and dimensions of the chassis.
•If you are using a telco rack, ensure that the weight of the chassis does not
make the rack unstable. Secure the telco rack with ceiling brackets if the rack
is populated with heavy equipment.
•Bolt the rack to the floor for stability.
Lifting the System
Observe the following general precautions when lifting the system:
•Disconnect all power and external cables before lifting the system.
•Ensure that your footing is solid and the weight of the system is evenly
distributed between your feet.
•Lift the system slowly, keeping your back straight. Lift with your legs, not
with your back. Bend at the knees, not at the waist.
•Depending on the weight of the system, more th an one person might be
required to lift it.
