•
For the cooling system to function properly, the airflow around the chassis must be
unrestricted. See “Cooling System and Airflow in a QFX5100 Device” on page 39 for
more information about the airflow through the chassis.
•
If you are mounting a QFX5100 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 atleast 24 in. (61 cm) both in front of and behind the QFX5100 device. 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.
