Note: For models M4300-28G-POE+ and M4300-52G-POE+, the switch automatically
selects the APS1000W PSU to provide the power and turns off the APS550W PSU. If the
APS1000W PSU is removed or fails, the switch uses the APS550W PSU to provide the
power and might reboot if the consumed power is more than the power that the
APS550W PSU can provide.

The PoE power budgets for models M430-16X, M4300-28G-POE+, and
