Aironet 1100 / 802.3af Power Over Ethernet (POE) Support

Question

I was under the impression that the Aironet 1100 supports 802.3af POE. I purchased a NetGear FS108P POE switch, however, when I plug in the 1100, it does not receive any power.
I have seen references in the documentation to a Cisco inline power injector and a Cisco Catalyst switch that can provide POE to the 1100 and maybe they will work, however, will the 1100 only work with those devices?? If so, it would seem that the 1100 really doesn't support the 802.3af standard and that Cisco's implementation of POE is proprietary.
Any input would be appreciated.
Thanks,
Michael

Hi Michael,
As you have discovered (unfortunately) is that the 1100 only supports Cisco Pre-standard PoE :( Have a look;
Single 802.11g radio offering 54 Mbps of capacity
2.4 GHz integrated diversity dipole antennas
Available in an autonomous version only
16 MB of memory with 8 MB of storage
Operating temperature range of 32 to 104?F (0 to 40?C)
**Inline power support (Cisco pre-standard)**
From this doc;

The good news is that either of the options you listed will work just fine. I would go for the power injector probably just for neatness sake.
POWERING OPTIONS
The Cisco Aironet 1100 Series can be powered either locally using the AC-DC power adapter, or over the Ethernet cable when coupled with a device capable of delivering in-line power, such as an in-line power-capable Cisco Catalyst? switch, Catalyst in-line power patch panel, or Cisco Aironet Power Injector.
The AC-DC power adapter is included with the access point and can also be ordered as a spare part. The Cisco Aironet Power Injector can either be configured to the order or can be ordered separately.
You can use either;
AIR-PWR-A= Cisco Aironet Power Supply-Input 110-240VAC, Output 48VDC, 380 mA-for 1100 and 1200 Series
AIR-PWRINJ3= Cisco Aironet Power Injector for the 1100 and 1200 Series Access Points

Hope this helps! And good luck!
