Powered Device Classes

Power Budget

Powered devices are grouped into the five classes listed in Table 10 on page 42. The classes are based on the amount of power the devices require. The switches support all five classes.

The AT-8100L/8POE and AT-8100L/8POE-E Switches have a power budget of 180 watts. The AT-8100S/24POE and AT-8100S/48POE Switches have a power budget of 370 watts. These are the maximum amounts of power the switches can provide at one time to the powered devices.

The AT-8100S/24POE and AT-8100S/48POE Switches have two power supplies. Each power supply is responsible for providing 185 watts, or half, of the power budget. Both power supplies must be connected to AC power sources for the switch to provide the full 370 watts. The power budget is reduced to 185 watts if only one power supply is connected to a power source.

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 of the devices. 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.

To determine whether the power requirements of the PoE devices you plan to connect to the switch exceed its power budget, refer to their documentation for their power requirements and add the requirements together. The switch should be able to power all of the devices simultaneously as long as the total is below its power budget. If the total exceeds the available power budget, you should consider reducing the number of PoE devices so that all of the devices receive power. Otherwise, the switch powers a subset of the devices, based on port prioritization.
