General Site Guidelines for EX Series Switches
Efficient switch 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 EX Series switch and
prevent environmentally caused equipment failures:
•
Keep the area around the chassis free from dust and conductive material, such as
metal flakes.
•
Followprescribedairflowguidelinestoensurethatthecoolingsystemfunctionsproperly
and that exhaust from other equipment does not blow into the intake vents of the
switch.
•
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 switch in a secure area, so that only authorized personnel can access the
switch.
