Cisco Aironet Power over Ethernet Application Note

PoE Requirements for Cisco Access Points

Note

A 1000BASE-T mid-span device is a product in the middle of the circuit that can provide power.
This product can be a powered Ethernet source, an injector, or other mechanism for inserting
PoE.

PoE Requirements for Cisco Access Points

To determine if a particular switch or PSE can supply enough power to an access point, the installer
needs to verify the amount of power the access point draws and confirm that there is enough power
present to operate it. Depending on the make, model, and radio configuration, the access point can draw
different amounts of power.

Table 1

presents the power requirements (in watts) for Cisco Aironet access

points.
