When planning your Cisco 7507 or Cisco 7507-MX rack installation, consider the following guidelines:
Allow at least 3 to 4 feet (0.91 to 1.22 m) of clearance behind the rack for maintenance. If the rack
•
is mobile, you can push it back within 1 foot (0.3 m) of a wall or cabinet for normal operation and
pull it out when necessary for maintenance (installing or replacing interface processors or power
supplies, or connecting network cables or interface units).
• The ports for cooling air are located on the front and rear of the chassis, so multiple routers can be
rack-mounted with little or no vertical clearance. However, avoid placing the router in an overly
congested rack.
• Consider the equipment and cabling that is already installed in the rack. Ensure that cables from
other equipment will not obstruct the airflow through the chassis or impair access to the power
supplies or interface processors. Route cables away from field-replaceable components to avoid
having 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.
