General Site Guidelines

Efficient device operation requires proper site planning and maintenance and proper layout of the equipment,
rack or cabinet (if used), 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 and 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.
