Chapter 3 Installing the ASA 5550 Installing the Chassis Installing the Chassis This section describes how to rack-mount and install the adaptive security appliance. You can mount the adaptive security appliance in a 19-inch rack (with a 17.5- or 17.75-inch opening). Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety. The following information can help plan equipment rack installation: • Allow clearance around the rack for maintenance. • When mounting a device in an enclosed rack ensure adequate ventilation. An enclosed rack should never be overcrowded. Make sure that the rack is not congested, because each unit generates heat. • When mounting a device in an open rack, make sure that the rack frame does not block the intake or exhaust ports. • If the rack contains only one unit, mount the unit at the bottom of the rack. • If the rack is partially filled, load the rack from the bottom to the top, with the heaviest component at the bottom of the rack. • If the rack contains stabilizing devices, install the stabilizers prior to mounting or servicing the unit in the rack. Warning Before performing any of the following procedures, ensure that the power source is off. (AC or DC). To ensure that power is removed from the DC circuit, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position. 78-19186-01 Cisco ASA 5500 Series Getting Started Guide 3-3
