Quesiton about the "2 Eethernet ports Network Module C3KX-NM-10GT" in switch 3750

[sam wang]

I just install the module (C3KX-NM-10GT) into switch 3750,  but it doesn't work.   I could not see any light at front panel when I connect an Ethernet cable to its port.     Do I need type a command to active it in switch3750 ? 

Thanks for help!

What is the model or exact part number of the switch?

No need for any commands. Once installed it should work.  What is your IOS version?
