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.

exhaust from other equipment does not blow into the intake vents of the device.

• Install the device in a secure area, so that only authorized personnel can access the device.
