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 asa wall. For the cooling system to function properly,
the airflow around the chassis must be unrestricted.
Figure 18 on page 61 shows the airflow in PoE models of EX2200 switches, except for
EX2200-C models. Figure 19 on page 62 shows the airflow non-PoE models of EX2200
switches, except for EX2200-C models.
