Prepare for Installation

Power Supply Considerations

When installing the ASA, consider the following:
• Check the power at the site before installing the chassis to ensure that it is "clean" (free of spikes and
• Install proper grounding for the site to avoid damage from lightning and power surges.
• The ASA chassis does not have a user-selectable operating range. Refer to the label on the chassis for
• Install an uninterruptible power source for your site, if possible.

Equipment Rack Configuration

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
• Be sure enclosed racks have adequate ventilation. Make sure that the rack is not overly congested as
