PoE optimizing

tgusset — Mon, 05 Jul 2021 09:34:28 GMT

I have a 2960s PoE Switch that powers some 2702 Access Points.

Each AP has 15,4 watts allocated:

show power inline
Gi1/0/23 auto on 15.4 AIR-CAP2702I-E-K9 4 30.0

But the effective power consumption is much less (between 6,3 and 6,8 watts)

show power inline Police
Gi1/0/23 auto on errdisable ok 15.4 6.3

In summary the power Budget of the Switch is

Module   Available     Used     Remaining
          (Watts)     (Watts)    (Watts)
------   ---------   --------   ---------
1           370.0      338.8        31.2

But the sum of operational power is only 144 watts

When I reduce the power per port to e.g. 12 watts

power inline consumption 12000

the Access Point disables its Radios because of low power.

Is there a way to optimize PoE for these Access Points?

Thanks in advance

These APs can work off or

These APs can work off or regular PoE 15.4w but will be in a 3x3 not 3x4. The power draw is defined in the datasheet.

Powering options

● 802.3at PoE+

● Enhanced PoE

● Cisco AP2700 power injectors (AIR-PWRINJ4=)

● Cisco AP2700 local power supply (AIR-PWR-B=)

Note: If 802.3af PoE is the source of power, the access point will dynamically shift from 3x4 to 3x3 and come up underPoE.
