Preventive Site Configuration: Maintaining Normal Operation

Planning a proper location for the Cisco 7206 and the layout of your equipment rack or wiring closet are
essential for successful system operation. Equipment placed too close together or inadequately
ventilated can cause system overtemperature conditions. In addition, chassis panels made inaccessible
by poor equipment placement can make system maintenance difficult. Following are precautions that can
help avoid problems during installation and ongoing operation.

If you are planning to install the cable-management brackets on a Cisco 7206 that you are
rack-mounting from the front, you must install the cable-management brackets and the rack-mount
brackets before you install the chassis in the rack.
Provide an adequate chassis ground (earth) connection for your router chassis.
We strongly recommend that you provide a chassis ground connection. Refer to
