Hello Simon,

look at the product overview PoE capability is declared compliant to 802.3af standard.

http://www.cisco.com/en/US/products/ps10020/index.html

be aware that:

a) this is an unmanaged device

b) POE is supported only on 4 ports

Power over Ethernet on four ports powers network-attached devices such as IP telephones, wireless access points, or video surveillance cameras directly over the connection, simplifying installation and eliminating the need ffor separate power supplies or an AC power outlet

Hope to help

Thanks for your reply Giuseppe.

I saw those details. I am really interested in the pre-802.3af standard that is used by the Aironet 1100. This doesn't support 802.3af but does use PoE using the old (pre-2003) Cisco method of inline power.

Did you ever find a answer to this? Specifically as to if 'inline' power works with this device?

Thanks

No. I didn't find out.

Instead I bought a cheap PoE switch from TP-Link and made an adapter that forced on the 48 volts by putting a 25K resister across 2 pins. However it does only work when you plug in my adapter then plug in the remote device. If it detects the remote device before PoE is enabled it doesn't enable it. That may be unique to the TP-Link switch and you might be able to mitigate it, but it was fine for my purpose.

Some details on how to do this are here: http://www.voip-info.org/wiki/view/Cisco+POE
