Clearance Requirements for Airflow and Hardware Maintenance for EX2200 Switches
When planning the site for installing an EX2200 switch, you must allow sufficient clearance around the installed switch (see Figure 1).

The power cord retainer clips extend out of the rear of the chassis by 3 in.
- Allow at least 6 in. (15.2 cm) of clearance
on the side between devices that have fans or blowers installed. Allow
2.8 in. (7 cm) between the side of the chassis and any non-heat-producing
surface such as a wall. For the cooling system to function properly,
the airflow around the chassis must be unrestricted.
Figure 2 shows the airflow in an EX2200 switch with network ports in which PoE is available. Figure 3 shows the airflow in an EX2200 switch with network ports in which PoE is not available.

- If you are mounting an EX2200 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 6 in. (15.2 cm) 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.
