GBIC-invalid error detected putting in err-disable state

[swilson1a]

I have a 3750x in which we installed a C3KX-SM-10G module if I look at the show switch service-modules it is showing connected. However as soon as I install the GLC-T transceiver in the gi1/1/2 in the module I get the following error "gbic-invalid error detected on Gi1/1/2, putting Gi1/1/2 in err-disable state" and when I look at the status for the interface it shows "err-disabled"

Any Ideas?

hi, 

as i know generally 10G modules and 1G modules are not compatible. you can check compatibility matrix

C3KX-SM-10G is a 10Gig module. If you need a 1/10Gig module, this is the part number"

C3KX-NM-10G
