Lee:
Are you sure it's not the hardware but the software that's coming out around
Christmas time? That was my rough understanding.
Kind regards,
Frank

I heard from Cisco 2 days ago that the 3750E and the modules that will
power their 1252 will be availble around the end of Dec/Januarary time
frame. I'm trying to pry out of HP if the 5400's and 3500's will be
firmware upgradable to the 802.3at standard and just not support as many
ports. The 5400 answer is that it will probably be a different module.
I haven't heard on the 3500.
I haven't heard a ratification date for the 802.3at standard, and I
heard that it was going to happen about the same time or after the
802.11n standard. I haven't followed that one as close, last I saw they
hadn't decided on 33 or 48 watts of power per port.

Good points, Philippe. For those organizations that want to be bleeding
edge, I don't think PoE concerns are going to hold them back. Every
vendor has a way to address them today in a way that's not a
show-stopper.
Has anyone heard from Cisco, Extreme, Foundry, HP, etc. on when 802.3at
switches/blades will be available?
Which 802.11n AP supports Etherchannel? It's my understanding that any
vendor who has a second Ethernet port on their AP is using it
exclusively for PoE (Trapeze's AP may be the exception).

Following the trail of discussion about 802.11n, I wouldn't be buying
802.11n before 802.3at (AKA Power over Ethernet PLUS) gears are on the
market. By then, 802.11n vendors should have only one Ethernet port to
the AP.
One port will bring savings on PoE injectors, Cabling, and even
switchports (if you were planning to etherchannel those two 100 Mbps
ports to one AP).
After all, a 48 ports 10/100/1000 switch is only 50% more expensive than
a 10/100 (in the Cisco world), one more reason to only have one cable
from the switch to the AP!
Last thing: According to a few websites, 802.3at will work over regular
cat5.
