Clearance Requirements for Airflow and Hardware Maintenance for a QFX3600 or QFX3600-I Device

When planning the site for installing a QFX3600 or QFX3600-I device, you must allow sufficient clearance around the installed device (see Figure 1).

  • 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.
