If you are mounting an EX3300 switch in a rack or cabinet with other equipment, or if
you are placing it on the desktop or floor near other equipment, ensure that the exhaust
from other equipment does not blow into the intake vents of the chassis.
•
Leave at least 24 in. (61 cm) in front of the switch and behind the switch. For service
personnel to remove and install hardware components, you must leave adequate
space at the front and back of the switch. NEBS GR-63 recommends that you allow
at least 30 in. (76.2 cm) in front of the rack or cabinet and 24 in. (61 cm) behind the
rack or cabinet.
