Hello Neil,

Yes, this is a layer 1 dilemna. Perhaps all the recent hardware does not have this problem and you do not have to worry about it? Anybody have any different experience?

If you look at something like
http://www.cisco.com/en/US/docs/switches/lan/catalyst3750e_3560e/hardware/installation/guide/HIGINSTL.html#wp1300410
there is an interesting statement, "The PoE ports provide PoE support for devices compliant with IEEE 802.3af and also provide Cisco pre-standard PoE support for Cisco IP Phones and Cisco Aironet Access Points."

Perhaps the lesson is watch out for old hardware as it is not necessarily compliant?

Thanks,
David
