Hi,
I was wondering, if I get the PoE switch module for a 2951, will I need a different image than c2951-universalk9-mz.SPA.151-4.M2.bin to be able to configure and use it?
Also, is the 4G WAN module backwards compatable with 3G?
More sh ver output from the 2951:
Technology Package License Information for Module:'c2951'

Thank you, Pat.

You don't need anything different from what you have now.

Thanks, Paolo.
what about the second question?
Also, is the 4G WAN module backwards compatable with 3G?
Thanks again, Pat.

I believe so. Full specifications are in the data sheet.
Reagardng the router I must correct myself. For a PoE switch module, you will need the PoE power supply.
Thank you for the nice rating and good luck!

Hi Paolo,
Do the Router 2951 need this power supply to provide PoE? I have a sm-es3g-16-p card, but I´ve look out documentation and I do not see any about this information. It says that the Router can support this card without problem, but the card does not provide power. What do you recommend for this case? The IOS version is
c2951-universalk9-mz.SPA.152-4.M4.bin and the IOS switch mosule is c3560e-universalk9-mz.122-52.EX1.bin
Hope you can help
thanks in advance

Hi Leo thanks for your answer, that´s what I´ve seen in several documents and seems it should not have any problem to work proprly, the version is compatible, it works with Router power supply, PoE is provided by default, I checked inside of Router to verify if there was a wire, which is connecting to Router motherboard, any message in boot section and so on. however, I have not founded an answer why this card does not provide power.
thanks for your help.

Omar - this is an old post and I'm not 100% sure if my memory serves but, I believe I had to order a different power supply than what came with the router to accommodate the PoE switch module.

Patrick is correct. You need a large PoE power supply to drive the PoE modules.
