EX2300 Cooling System

 

The cooling system in EX2300 switches—except EX2300-C which is the compact, fanless model, EX2300-24MP, and EX2300-48MP models—consists of two fans built-in 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.

The cooling system in EX2300-24MP switches consists of three fans built in along the right side panel of the chassis that provide side-to-side chassis cooling. The cooling system in EX2300-48MP switches consists of four fans built in along the right side panel of the chassis that provide side-to-side chassis cooling.

Under normal operating conditions, the fans operate at a moderate speed to reduce noise. Temperature sensors in the chassis monitor the temperature within the chassis. If any fan fails or if the temperature inside the chassis rises above the threshold, the switch raises an alarm and all functioning fans operate at a higher speed than normal. If the temperature inside the chassis rises above the threshold, the switch shuts down automatically.
