General Site Requirements Chapter 2 Preparing for Installation General Site Requirements The topics in this section describe the requirements your site must meet for safe installation and operation of your system. Ensure that your site is properly prepared before beginning installation. This section includes the following topics: • Site Environment, page 2-4 • Preventive Site Configuration, page 2-4 • Power Supply Considerations, page 2-4 • Configuring Equipment Racks, page 2-6 Site Environment Place the chassis on a desktop or mount it on a rack. The location of the chassis and the layout of the equipment rack or wiring room are extremely important for proper system operation. Equipment placed too close together, inadequate ventilation, and inaccessible panels can cause system malfunctions and shutdowns, and can make the chassis maintenance difficult. For information on physical specifications, see table 7 at the following url: http://www.cisco.com/en/US/prod/collateral/vpndevc/ps6032/ps6094/ps6120/product_data_sheet0900a ecd802930c5.html. When planning the site layout and equipment locations, keep in mind the precautions described in the next section "Preventive Site Configuration, page 2-4," to help avoid equipment failures and reduce the possibility of environmentally caused shutdowns. If you are currently experiencing shutdowns or unusually high error rates with your existing equipment, these precautions may help you isolate the cause of failures and prevent future problems. Preventive Site Configuration The following precautions will help plan an acceptable operating environment for the chassis and avoid environmentally caused equipment failures: • Electrical equipment generates heat. Ambient air temperature might not be adequate to cool equipment to acceptable operating temperatures without adequate circulation. Ensure that the room in which you operate your system has adequate air circulation. • Always follow the ESD-prevention procedures described previously to avoid damage to equipment. Damage from static discharge can cause immediate or intermittent equipment failure. • Ensure that the chassis top panel is secure. The chassis is designed to allow cooling air to flow effectively within it. An open chassis allows air leaks, which may interrupt and redirect the flow of cooling air from the internal components. Power Supply Considerations For information on power supply considerations including environmental operating ranges and power requirements, see table 7 at the following url: http://www.cisco.com/en/US/prod/collateral/vpndevc/ps6032/ps6094/ps6120/product_data_sheet0900a ecd802930c5.html Cisco ASA 5500 Series Hardware Installation Guide 2-4 78-17989-01
