Guidelines for Particulate Matter
Cisco Ethernet Switches are equipped with cooling mechanisms, such as fans and blowers. However,
these fans and blowers can draw dust and other particles, causing contaminant buildup inside the chassis,
which can result in a system malfunction.
You must install this equipment in an environment as free as possible from dust and foreign conductive
material (such as metal flakes from construction activities).
