General Site Guidelines
Ecient device operaon requires proper site planning and maintenance. It also requires proper layout
of the equipment, rack or cabinet, and wiring closet.
To plan and create an acceptable operang environment for your device and prevent environmentally
caused equipment failures:
• Keep the area around the chassis free from dust and conducve material, such as metal akes.
• Follow prescribed airow guidelines to ensure that the cooling system funcons properly. Ensure
that exhaust from other equipment does not blow into the intake vents of the device.
