Physical Rack Precautions
•
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 com-
ponent at a time. Extending two or more simultaneously may cause the rack to become unstable.
Warning:
Follow these guidelines to prevent injury. Take all precautions to ensure the system remains stable
General Server Precautions
•
Review the electrical and general safety precautions that came with the components 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.
•
Allow the hard drives and power supply modules to cool before touching them.
•
Always keep the rack front door, all panels and all components on the servers closed when not servicing,
to maintain proper cooling.
Warning

proof seal over the screws that looks like this:
