Under no circumstances should you stack one chassis on top of one another. This disrupts cooling air flow to
the chassis and causes damage to the hardware.
Warning
See Hardware Specifications, on page 14 for information about physical specifications.
To avoid equipment failures and reduce the possibility of environmentally caused shutdowns, plan the site
layout and equipment locations carefully. If you are currently experiencing shutdowns or unusually high error
rates with your existing equipment, these considerations may help you isolate the cause of failures and prevent
future problems.
Site Considerations
Considering the following helps you plan an acceptable operating environment for the chassis, and avoid
environmentally-caused equipment failures.
• 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 14 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.
