Clearance Requirements for Airflow and Hardware Maintenance for a
QFX3500 Device
When planning the site for installing a QFX3500 device, you must allow sufficient clearance around the
installed chassis (see
).

•
For the cooling system to function properly, the airflow around the chassis must be unrestricted. See
Cooling System and Airflow for a QFX3500 Device for more information about the airflow through the
chassis.
•
If you are mounting a QFX3500 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 QFX3500 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.
