Figure 1-4. Rack Mounting the Appliance
Appliance Precautions
w
Determine the placement of each component in the rack before you install the rail.
w
Install the heaviest appliance first, at the bottom of the rack, and then work
upward. Distribute the load on the rack evenly. An unbalanced rack is hazardous.
w
Allow the power supply units and hard drives to cool before touching them.
w
Install the equipment near an electrical outlet for easy access.
w
Mount equipment in a rack with sufficient airflow for safe operation.
w
For a closed or multiple-unit rack assembly, the ambient operating temperature of
the rack environment might be greater than the ambient temperature of the room.
Therefore, consider the lowest and highest operating temperatures of the
equipment when making a decision about where to install the appliance in the rack.
Rack Precautions
w
Make sure 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.
w
For a single-rack installation, attach a stabilizer to the rack.
w
For a multiple-rack installation, couple (attach) the racks together.
w
Always make sure that the rack is stable before extending a component from the
rack.
w
Extend only one component at a time. Extending two or more simultaneously might
cause the rack to become unstable.
