equipment rooms, service closets and the like).
•
This product is not suitable for use with visual display work place devices
acccording to §2 of the the German Ordinance for Work with Visual Display Units.
2-4 Warnings and Precautions
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.
•
Always make sure the rack is stable before extending a component from the
rack.
•
You should extend only one component at a time - extending two or more si-
multaneously may cause the rack to become unstable.
Server Precautions
•
Review the electrical and general safety precautions in Chapter 4.
•
Determine the placement of each component in the rack before you install the
rails.
•
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 any hot plug drives and power supply modules to cool before touching
them.
•
Always keep the rack's front door and all panels and components on the servers
closed when not servicing to maintain proper cooling.
Rack Mounting Considerations
Ambient Operating Temperature
If installed in a closed or multi-unit rack assembly, the ambient operating tempera-
ture of the rack environment may be greater than the room's ambient temperature.
Therefore, consideration should be given to installing the equipment in an environ-
ment compatible with the manufacturer’s maximum rated ambient temperature
(Tmra).
Reduced Airflow
Equipment should be mounted into a rack so that the amount of airflow required
for safe operation is not compromised.
Mechanical Loading
Equipment should be mounted into a rack so that a hazardous condition does not
arise due to uneven mechanical loading.
Circuit Overloading
Consideration should be given to the connection of the equipment to the power
supply circuitry and the effect that any possible overloading of circuits might have
on overcurrent protection and power supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.
Reliable Ground
A reliable ground must be maintained at all times. To ensure this, the rack itself
should be grounded. Particular attention should be given to power supply connec-
tions other than the direct connections to the branch circuit (i.e. the use of power
strips, etc.).
Warning! To prevent bodily injury when mounting or servicing this unit in a
rack, you must take special precautions to ensure that the system remains
stable. The following guidelines are provided to ensure your safety:
•
This unit should be mounted at the bottom of the rack if it is the only unit in
the rack.
•
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 the rack is provided with stabilizing devices, install the stabilizers before
mounting or servicing the unit in the rack.
