QFX5110 Clearance Requirements for Airflow and Hardware Maintenance
When planning the site for installing a QFX5110, you must allow sufficient clearance
around the installed chassis (see Figure 21 on page 55).

for a QFX5110
•
For the cooling system to function properly, the airflow around the chassis must be
unrestricted. See “QFX5110 Cooling System and Airflow” on page 25 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.
