those within which the Cisco 7204 will continue to operate; however, a measurement that is approaching
the minimum or maximum of a range indicates a potential problem. You can maintain normal operation
by anticipating and correcting environmental anomalies before they approach a maximum operating
range.

Maintain a minimum clearance of three inches on the right and left of the chassis for the cooling air
inlet and exhaust ports, respectively. Avoid placing the Cisco 7204 in an overly congested rack or
directly next to another equipment rack; otherwise, the heated exhaust air from other equipment can
enter the inlet air vents and cause an overtemperature condition inside the router.
Always install heavier equipment in the lower half of a rack to maintain a low center of gravity and
prevent the rack from falling over.
If you use telco-type racks, be sure that the rack is bolted to the floor and secured because in these
types of installations only one end of the chassis mounts to the two rack posts with the brackets.
Ensure that the weight of the chassis does not make the rack unstable.
Install and use the cable-management bracket included with the Cisco 7204 to keep cables organized
and out of the way of the port adapters and I/O controller. Consider the equipment and cabling that
is already installed in the rack. Ensure that cables from other equipment will not impair access to
the port adapters, or require you to disconnect cables unnecessarily to perform equipment
maintenance or upgrades.
If you are planning to install the cable-management brackets on a Cisco 7204 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 the section
