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 power conversion apparatus includes M first slots, wherein each of M first slots is electrically connected to an input side of one of N first bus bars, and a respective first slot of the M first slots is electrically connected to a first module that can supply an alternating current or a direct current to the first bus bar electrically connected to the first slot. The apparatus further includes P second slots, wherein each of the P second slots is electrically connected between an output side of one of the N first bus bars and an input side of one of second bus bars, and a respective second slot of the P second slots is electrically connected to a second module that converts an alternating current into a direct current or that converts a direct current into a direct current.
