Clearance Requirements for Airflow and Hardware Maintenance for EX3300 Switches

When planning the site for installing an EX3300 switch, you must allow sufficient clearance around the installed switch (see Figure 13).

Figure 13: Clearance Requirements for Airflow and Hardware Maintenance for EX3300 Switches

Clearance Requirements
for Airflow and Hardware Maintenance for EX3300 Switches

The power cord retainer extends out of the rear of the chassis by 3 in. (7.62cm).

Follow these clearance requirements:

  • For the cooling system to function properly, the airflow around the chassis must be unrestricted. See Figure 14 and Figure 15.

  • If you are mounting an EX3300 switch in a rack or cabinet with other equipment, or if you are placing it on the desktop or floor near 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) in front of the switch and behind the 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.
