For the cooling system to function properly, the airflow around the chassis must be
unrestricted. See "QFX5200 Cooling System and Airflow" on page 17
information about the airflow through the chassis.
If you are mounting a QFX5200 in a rack or cabinet with 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) both in front of and behind the QFX5200. 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.
