General Site Guidelines
Efficient device operation 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 operating environment for your device and prevent environmentally
caused equipment failures:
• Keep the area around the chassis free from dust and conductive material, such as metal flakes.
• Follow prescribed airflow guidelines to ensure that the cooling system functions properly. Ensure
that exhaust from other equipment does not blow into the intake vents of the device.
• Follow the prescribed electrostatic discharge (ESD) prevention procedures to prevent damaging the
equipment. Static discharge can cause components to fail completely or intermittently over time.
• Install the device in a secure area, so that only authorized personnel can access the device.
