Juniper EX4600 Series User Manual

Figure 15: Clearance Requirements for Airflow and Hardware Maintenance
for a EX4600 Switch
•
For the cooling system to function properly, the airflow around the chassis must be
unrestricted. See “Cooling System and Airflow in an EX4600 Switch” on page 13 for
more information about the airflow through the chassis.
•
If you are mounting an EX4600 switch 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 EX4600 switch. 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.
