Power budget
The x230 Series PoE switches have the following power budgets:
AT-x230-10GP: 124 watts
AT-x230-18GP: 247 watts
AT-x230-28GP: 370 watts
This is the maximum amount of power the switches can provide at one
time to the powered devices.
The power requirements of the PoE devices determine the maximum
number of devices the switch can support at one time. So long as the total
power requirements of the powered devices is less than the power budget
of the switch, the switch can supply power to all the devices. But if the total
power requirements exceed the power budget, the switch denies power to
one or more ports using a mechanism referred to as port prioritization.
