3Chassis Installation
The Cisco
In a fully loaded chassis, the removable components (modules, line cards) weigh approximately 184 lbs. To enable two people to install the system safely, we recommend that the following components be removed from the chassis before installing the chassis in the rack:
•Fan assembly (13.0 lbs— optional, it is recommended to leave this installed)
•DC power supplies (15.5 lbs each)
•Supervisor cards (5.5 lbs each)
•TCC cards (2.0 lbs each)
•RF switch cards (2.5 lbs— optional, given the quantity and total weight contribution of these cards)
•RF line cards (9.5 lbs each)
Caution You must use a hydraulic lift or forklift to move a fully populated chassis.
Installation Methods
•Front mount or mid mount
•In a 19 inch wide (standard),

General Rack Installation Guidelines
When planning your rack installation, consider the following guidelines:
•The Cisco
•Before using a particular rack, check for obstructions (such as a power strip) that could impair
•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 for maintenance (installing or moving cards, connecting cables, or replacing or upgrading components). Otherwise, allow 36 inches (914.4 mm) of access to remove field replaceable units.
•Maintain a minimum clearance of 4 inches (101.6 mm) on the front and the rear of the chassis for the cooling air inlet and exhaust ports, respectively. Avoid placing the chassis in an overly congested rack or directly next to another equipment rack; otherwise, the heated exhaust air from the other equipment can enter the inlet air vents and cause a high temperature condition inside the router.
Caution To prevent chassis overheating, never install a Cisco
