Clearance Requirements for Airflow and Hardware Maintenance for EX3200 and

EX4200 Switches

When planning the site for installing an EX3200 or EX4200 switch, you must allow

sufficient clearance around the installed switch (see Figure 27 on page 91).

Figure 27: Clearance Requirements for Airflow and Hardware Maintenance for EX3200

and EX4200 Switches

■ 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

28 on page 92 shows the airflow through the EX3200 switch chassis and Figure

29 on page 92 shows the airflow through the EX4200 switch chassis.

■ If you are mounting an EX3200 or EX4200 switch on 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) both in front of and behind the EX3200 or EX4200

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.
