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.

Pluggable module

A monitoring circuit includes a configuration interface, a control circuit, a detection circuit, a direct current voltage source, a switch circuit, and a first resistor. A first end of the configuration interface is separately connected to the direct current voltage source and an input end of the switch circuit; a second end of the configuration interface is separately connected to a first end of the first resistor and an output end of the switch circuit; a control end of the switch circuit is connected to the control circuit; a second end of the first resistor is grounded; the detection circuit is connected to the first end of the first resistor; the configuration interface is configured to connect to a dry contact; the control circuit controls closing or opening of the switch circuit; and the detection circuit detects a voltage between two ends of the first resistor.
