SC835B Chassis Manual
Circuit Overloading
Avoid overloading the power supply circuitry or any overcurrent protection equip-
ment. Use equipment nameplate ratings to calculate your requirements.
Reliable Ground
A reliable ground must be maintained at all times. To ensure this, ground the rack,
itself. Pay attention to power supply connections other than the direct connections
to the branch circuit, such as power strips.
Physical Rack Precautions
Warning: Follow these guidelines to prevent injury. Take all precautions to
ensure the system remains stable.
•
Ensure that the leveling jacks on the bottom of the rack are fully extended to
the floor with the full weight of the rack resting on them.
•
In single rack installation, stabilizers should be attached to the rack.
•
In multiple rack installations, the racks should be coupled together.
•
When mounting this unit in a partially filled rack, load the rack from the bottom
to the top with the heaviest component at the bottom of the rack. If this is the
only unit in the rack, mount it at the bottom.
•
Always make sure the rack is stable before extending a component from the
rack. Extend only one component at a time. Extending two or more simultane-
ously may cause the rack to become unstable.
General Server Precautions
•
Review the electrical and general safety precautions that came with the com-
ponents you are adding to your chassis.
•
Determine the placement of each component in the rack.
•
Install the heaviest server components on the bottom of the rack first, and
then work up.
•
Use a regulating, uninterruptible power supply (UPS) to protect the server
from power surges, voltage spikes and to keep your system operating in case
of a power failure.
