Important Note:
The appliance is designed for use in rack systems.
Functional reliability outside of a rack cannot be guaranteed.
Warnings and Precautions
The appliance can be operated safely if you observe the following notes and
the notes on the appliance itself.
Rack Precautions
Ì
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.
Ì
In single rack installation, stabilizers should be attached to the rack.
Ì
In multiple rack installations, the racks should be coupled together.
Ì
Always make sure the rack is stable before extending a component from
the rack.
Ì
You should extend only one component at a time–extending two or more
simultaneously may cause the rack to become unstable.
General Server Precautions
Ì
Review the electrical and general safety precautions that came with the
components you are adding to your appliance.
Ì
Determine the placement of each component in the rack before you install
the rails.
Ì
Install the heaviest server components on the bottom of the rack first, and
then work up.
Ì
Allow the hot plug hard drives and power supply modules to cool before
touching them.
Ì
Always keep the rack‘s front door, all panels, and server components
closed when not servicing to maintain proper cooling.
Rack Mounting Considerations
Ì
Ambient operating temperature:
If installed in a closed or multi-unit rack
assembly, the ambient operating temperature of the rack environment
may be greater than the ambient temperature of the room. Therefore,
you should install the equipment in an environment compatible with the
manufacturer’s maximum rated ambient temperature.
Ì
Reduced airflow:
Equipment should be mounted into a rack to allow
enough airflow to keep the equipment cool.
Ì
Mechanical loading:
Equipment should be mounted into a rack so that a
hazardous condition does not arise due to uneven mechanical loading.
