for maintenance

24 in. (60.9 cm)

For the cooling system to function properly, the airflow around the chassis must be unrestricted. See

Cooling System and Airflow for QFX3600 and QFX3600-I Devices for more information about the airflow

through the chassis.

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.
