• Electrical equipment generates heat. Ambient air temperature might not be adequate to cool equipment
to acceptable operating temperatures without adequate circulation. Make sure that the room in which
you operate your system has adequate air circulation.
• Ensure that the chassis cover is secure. The chassis is designed to allow cooling air to flow effectively
within it. An open chassis allows air leaks, which may interrupt and redirect the flow of cooling air from
the internal components.
• Always follow ESD-prevention procedures to avoid damage to equipment. Damage from static discharge
can cause immediate or intermittent equipment failure.
Power Supply Considerations
See Features, on page 1 and Hardware Specifications, on page 11 for more detailed information about the
power supply in the chassis.
When installing the chassis, consider the following:
• Check the power at the site before installing the chassis to ensure that it is free of spikes and noise. Install
a power conditioner, if necessary, to ensure proper voltages and power levels in the appliance-input
voltage.
• 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 for the chassis; make sure that you have the
correct style for your site.
• Install an uninterruptible power source for your site, if possible.
Rack Configuration Considerations
See Rack-Mount the Chassis, on page 31 for the procedure for rack-mounting the chassis.
Consider the following when planning a 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.
• If your rack includes closing front and rear doors, the doors must have 65 percent open perforated area
evenly distributed from top to bottom to permit adequate airflow.
• 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.
