catalyst 9407 ports problem

[osman.elhanafy]

Dears,
We have cisco catalyst 9407 and we inserted only 4 linecards oo it.
some ports on the module 6 (line card 4) doesn't work with ip phone (the phone doesn't register) no problem in power.
When i change the phone from these ports to another port on the same module or another modules , the phone is working fine.
did anyone face this problem before?

thanks,

Hi,

You may have a bad module. What is the part number for the module?
