•
Install proper grounding for the site to avoid damage from lightning and power surges.
•
The chassis does not have a user-selectable operating range. Refer to the label on the chassis for the
correct appliance input-power requirement.
•
Several styles of AC-input power supply cords are available; make sure that you have the correct style
for your site.
•
Install an uninterruptible power source for your site, if possible.
•
If you are using dual redundant (1+1) power supplies, we recommend that you use independent electrical
circuits for each power supply.
Equipment Rack Configuration Considerations
Consider the following when planning an equipment-rack configuration:
•
If you are mounting a chassis in an open rack, make sure that the rack frame does not block the intake
or exhaust ports.
•
Be sure enclosed racks have adequate ventilation. Make sure that the rack is not overly congested as
each chassis generates heat. An enclosed rack should have louvered sides and a fan to provide cooling
air.
•
In an enclosed rack with a ventilation fan in the top, heat generated by equipment near the bottom of
the rack can be drawn upward and into the intake ports of the equipment above it in the rack. Ensure
that you provide adequate ventilation for equipment at the bottom of the rack.
•
Baffles can help to isolate exhaust air from intake air, which also helps to draw cooling air through the
chassis. The best placement of the baffles depends on the airflow patterns in the rack. Experiment with
different arrangements to position the baffles effectively.
