Clearance Requirements for Airflow and Hardware Maintenance for a QFX3500 Device

If you are mounting a QFX3600 or QFX3600-I device 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 QFX3600 or QFX3600-I
device. For service personnel to remove and install hardware components, you must
leave adequate space at the front and back of the device. 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.
