Cooling System and Airflow in an EX2300 Switch
The cooling system in EX2300 switches—except EX2300-C which is the compact, fanless
model—consists of two fans along the rear of the chassis that provide front-to-back
chassis cooling.
The cooling system in EX2300-C switches consists of the vents on the top of the chassis
and the heatsinks installed in the rear panel in PoE models. Do not block the vents on
the chassis; doing so can lead to overheating of the switch chassis.
