Hi BAZ,
The AP heat dissipation mechanism is as follows:
Cold air enters the housing from the bottom and side of the AP, and hot air escapes from the top of the AP by the chimney effect. To ensure good heat dissipation, ensure that the AP is mounted upright on a wall or in a cassette. At least 200 mm of space must be reserved around the top, bottom, two sides, and front of the device to ensure heat dissipation. Do not install it on a ceiling or on a desktop.
Do not install devices near heat sources, such as stoves and heaters.
Ensure that the air is well ventilated in the installation environment.
Do not block the heat dissipation holes of the device.
