Installation Preparation
Always follow ESD-prevention procedures when removing and replacing components. Ensure that the chassis
is electrically connected to an earth ground. Wear an ESD-preventive wrist strap, ensuring that it makes good
skin contact. Connect the grounding clip to an unpainted surface of the chassis frame to safely ground ESD
voltages. To properly guard against ESD damage and shocks, the wrist strap and cord must operate effectively.
If no wrist strap is available, ground yourself by touching the metal part of the chassis.
For safety, periodically check the resistance value of the antistatic strap, which should be between one and
10 megohms.
Site Environment
See
Hardware Specifications, on page 29
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
• Ensure that the chassis cover is secure. The chassis is designed to allow cooling air to flow effectively
• Always follow the ESD-prevention procedures described previously to avoid damage to equipment.
Power Supply Considerations
See the
supply modules in the Firepower 9300.
When installing the chassis, 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 chassis does not have a user-selectable operating range. Refer to the label on the chassis for the

operate your system has adequate air circulation.
within it. An open chassis allows air leaks, which may interrupt and redirect the flow of cooling air from
the internal components.
Damage from static discharge can cause immediate or intermittent equipment failure.
