Abstract: The heat exchange module is used in the cabinet that includes a cabinet body. The cabinet body has a first space and a second space. A temperature of the first space is higher than a temperature of the second space. The heat exchange module has a first air circulation system and a second air circulation system, and heat exchange may be performed between the first air circulation system and the second air circulation system. Both an air intake vent and an air exhaust vent of the first air circulation system are configured to be connected to the first space. An air exhaust vent of the second air circulation system is connected to an external space, and an air intake vent of the second air circulation system can be configured to be selectively connected to the external space and/or the second space.

Abstract: A pluggable module includes a power control unit, an interface unit, a monitoring unit, and a signal linkage unit. The power control unit is connected to the interface unit, and the pluggable module can be inserted into an external device by using the interface unit. One end of a pull ring is rotatably connected to a bracket, and the other end can trigger a signal switch. When the pull ring is in an ON state, the signal switch is triggered to send a first switch signal, or when the pull ring is in an OFF state, the signal switch sends a second switch signal. The monitoring unit is configured to control, upon receiving the first switch signal, the power control unit to be powered on, or control, upon receiving the second switch signal, the power control unit to be powered off.
