Using PwrInj3 power injector with Aironet 1815i

[mmostafa]

can I user Cisco PWRINJ3 to power up a Cisco Aironet 1815i, I already have one but the AP is not powering up. is it not compatible? and why?

thanks,

Hi there,

The 1815i datasheet states that is requires a 802.3af/at compliant power source. You will need a AIR-PWRINJ5= or AIR-PWRINJ6= .

cheers,

there is no work around to use the PWRINJ3 with it ?

I'm afraid the AIR-PWRINJ3 is pre-802.3af so will not be able to power the AP.
