General Site Guidelines
This topic applies to hardware devices in the EX Series product family, which includes
switches, the EX Series Redundant Power System (RPS), and the XRE200 External
Routing Engine.
This topic also applies to hardware devices in the QFX Series.
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 ESD prevention procedures to avoid 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.
