POE - Aironet 350 / 7940 IP Phone?

Hi All,

I recently purchased a POE Injector from Solwise to power my Cisco Aironet

350. Rather disappointingly, it doesn't appear to work.

According to the Cisco website, the Cisco Aironet 350 should support the current IEEE 802.3af and pre-standard POE, which I would understand as meaning that it should support power injectors which do not have any 'sensing' mechanisms, such as the device I purchased:

I've also tested the POE Injector with a Cisco 7940 IP phone and have found that it will not power the phone either.

Has anyone had any similar experiences or a solution to this problem? I thought the POE Injector would be cheap and cheerful way of providing power to my POE devices without having to stretch to a POE switch.

Any help appreciated,

RG

I don't know about the Aironet, but the 7940 uses reverse polarity. I'm powering 7940 and 7960 phones using 3Com PW130 PoE injectors and a crossover PoE cable (4-5 and 7-8 are switched at one end).

Certainly. You may also want to look at the D-Link PWL-50, which regulates the 48V from a 802.3af PoE network down to 12 or 5 volts, making it possible to power just about any camera, workgroup switch or wireless access point.

Aironet 350, 1100 and 1200 are *not* 802.3af compatible. The 350 comes with a power injector, the Powerinjector for 1100/1200 does work well too. (POWERINJ3 + external 48V power supply).

Where did you read this? The 1130 AP yes, but the older ones not.
