PoE not feeding power to 1252 AP on CAT image 6509

Unanswered Question
Dec 17th, 2009

I have a 6509 running a CATOS image cat6000-sup2cvk8.8-4-5.bin. My modules are mostly WS-X6148-GE-TX ( with daughter cards  WS-F6K-VPWR-GE)  with one WS-X6148-RJ45V so they are all PoE capable.. However , when I plugged my AP into the ports, I'm not getting any power. I also don't believe that my switch is overdrawing power as they are no PoE devices here even though I have all these PoE modules. The set port powerinline auto command is on because it's a default setting and it has not been turned off... The other thing I see is my power is that for some reason PS2 capacity is showing up as" none"  but I don't  think that's an issue but I should check on it for other obvious reason.. here the snapshot of my power environment. What going on here ? Is it becaue my image is not supporting PoE ?
thanks in advance..

The 1250 requires 19.5w of power to operate both radios at full MCS rate.  If you want to operate both radios (at 15.4w) then you need to upgrade the IOS of the 1250 to 12.4(10b)JDA3.  The IOS will upgrade the both radio's firmware so the AP can operate both radios BUT at a lower MCS rate.

Does this help you?  Please don't forget to rate my post.

The problem is not the lower power as you still should be able to power up the AP abeit with the lower throughput. The issue is that it don't power up the APs at all. At some site, I power up 1252 with older power supplies which is the lower power and they still power up.. We are just leveraging what we have for now...

I'm taking a punt here because it's been awhile with CatOS.  According to your post I believe you have 7.14w available.  Is is less than half of the minimum requirement for a 1250 (15.4w if you are running the correct IOS).

Can someone contradict me here???
