Figure 45: Clearance Requirements for Airflow and Hardware Maintenance for a QFX5110
For the cooling system to function properly, the airflow around the chassis must be unrestricted. See
QFX5110 Cooling System and Airflow Description for more information about the airflow through the
chassis.
If you are mounting a QFX5110 in a rack 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 QFX5110. 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.
