Hot-Swap Process
The AM4320 AMC has the ability to be hot-swapped in and out of an AMC Carrier/Chassis. The onboard MMC
manages the AMC's power-up and power-down transitions. The list below illustrates this process for a power-
down request.
1 Ejector latch is opened. HOT_SWAP_PB# assertion. MMC firmware detects the assertion of this signal.
2 MMC sends "Module Handle Open" event message to AMC Carrier. The corresponding M state of AMC
moves from M4-> M5.
3 AMC moves from M5 -> M6 if the ShMC grants the request and then sends the FRU Control requesting
quiesced state to the AMC.
4 The firmware deasserts payload power and sends "Module Quiesced" event message to the AMC where it
transitions from M6 to M1 state.
