Caution To prevent chassis overheating, never install the router in an enclosed rack that is not properly ventilated or air-conditioned.

When planning your Cisco 7505 rack installation, consider the following guidelines:

•Install the router in an open rack whenever possible. If installation in an enclosed rack is unavoidable, ensure that the rack has adequate ventilation.

•Allow sufficient clearance around the rack for maintenance. If the rack is mobile, you can push it back near a wall or cabinet for normal operation and pull it out when necessary for maintenance (installing or moving interface processors, connecting cables, or replacing or upgrading components).

•Maintain a minimum clearance of 2 inches (5.08 cm) on each side of the chassis for the cooling air inlet and exhaust ports. Avoid placing the router in an overly congested rack or directly next to another equipment rack. Otherwise, the heated exhaust from other equipment can enter the inlet air vents and cause an overtemperature condition inside the router.

•Install and use the cable-management brackets included with the router to keep cables organized and out of the way. Consider the equipment and cabling that is already installed in the rack. Ensure that cables from other equipment will not impair access to the interface processors or require you to disconnect cables unnecessarily to perform equipment maintenance or upgrades.

•Install heavier equipment in the lower half of the rack to maintain a low center of gravity.
