If you are mounting the switch on a rack or cabinet along with other equipment, ensure
that the exhaust from other equipment does not blow into the intake vents of the
chassis.
•
Leave at least 6 in. (15.2 cm) clearance in the front of and behind the chassis for airflow.
•
Leave at least 6 in. (15.2 cm) clearance on the left of the chassis for installing the
grounding lug.
•
Leave at least 24 in. (61 cm) clearance in front of and behind the switch for service
personnel to remove and install hardware components. See
