Caution: Carefully read all precautions and instructions before installation.
Equipment Rack Precautions
The equipment rack must be anchored to an unmovable support to prevent it from falling
over when one or more servers are extended in front of it on slide assemblies. The
equipment rack must be installed according to the manufacturer's instructions. You must
also consider the weight of any other device installed in the rack.
You are responsible for installing an AC power disconnect for the entire rack unit. This
main disconnect must be readily accessible, and it must be labeled as controlling power
to the entire unit, not just to the server(s).
To avoid the potential for an electrical shock hazard, you must include a third wire safety
grounding conductor with the rack installation. If server power cords are plugged into AC
outlets that are part of the rack, then you must provide proper grounding for the rack
itself. If server power cords are plugged into wall AC outlets, the safety grounding
conductor in each power cord provides proper grounding only for the server. You must
provide additional, proper grounding for the rack and other devices installed in it.
The server is designed for an AC line voltage source with up to 20 amperes of over
current protection. If the power system for the equipment rack is installed on a branch
circuit with more than 20 amperes of protection, you must provide supplemental
protection for the server. If more than one server is installed in the rack, the power source
for each server must be from a separate branch circuit.
Temperature: The operating temperature of the server, when installed in an equipment
rack, must not go below 10° C (50° F) or rise above 35° C (95° F). Extreme fluctuations in
temperature can cause a variety of problems in your server.
The equipment rack must provide sufficient airflow to the front of the server to maintain
proper cooling.
Rack Precautions
Caution: Carefully read all precautions and instructions before installation.
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 a single rack installation, stabilizers should be attached to the rack.
In multiple rack installations, the racks should be coupled together.
Make sure the rack is stable before extending a component from the rack.
Extend only one component at a time - extending two or more simultaneously may cause
the rack to become unstable.
The equipment rack must be anchored to an unmovable support to prevent it from falling
over when one or more servers are extended in front of it on slide assemblies. The
equipment rack must be installed according to the manufacturer's instructions. You must
also consider the weight of any other device installed in the rack.
