We have a catalyst 6506-e chassie. I have just installed a new 24 por gigabit eithernet module into. When I do a show config the 6506 recognizes the new module but the status light is not on and when I plug a switch into one of the new ports it does not recognize the connection. Is there something I need to do to turn on the new module?

Thanks in advance.

    You may need to enable it. Do a no shut on the interface

    I have tried that but with no luck. When I run the show interface command for that interface it says:

    Line protocol is down(not connected) even tho I have a switch connected to that port. If the port was not turned on it would say administrativly down.

    If I plug the switch into a port that is not on the new module that has the same configuration I get a link light no problem.

    I must be missing some step after installing the new module.

    when I do a show module I see the following:

    I am thinking the pwrdeny is the problem. Does anyone know why I would be getting this?

    If there is not enough power for all previously powered-up modules, some modules are powered down and marked as power-deny in the show module Status field.  Check this out

    We ended up having to pull in more power.
