10GB-T module (C3KX-NM-10GT) issue on 3750 stack

[Travis Ryan]

I purchased one two port 10GB-T ports network module (C3KX-NM-10GT) for my 3750-X switch stack (4 in the stack). After powering off the entire stack, plugging the module in, re-powered everything. When I run a "sh ip int bri" I see not two but eight 10GB ports. Two for each switch in the stack. Not only that but when I try to plug something into the module it still shows (notconnect) state.

I tried checking the recommend IOS version but the only documentation I could find was on the (C3KX-NM-10G) module, ( http://www.cisco.com/c/en/us/td/docs/interfaces_modules/transceiver_modules/compatibility/matrix/OL_6981.pdf ). This shows an IOS version of 12.2(53)SE. I have 12.2(58)SE so this should be good?

Is this an issue with IOS incompatibility or some other issue with the switch stack? Does anyone know the recommended version of IOS for this module?

Hi,

I think, you need IOS 15.0(1)SE or later. 

see table-1 in this link:

Go HERE.

Documentation shows you need, a mimimum of, 15.0(1)SE.  Personally, I'd recommend you stay away from this version and go directly to 15.0(2)SE4.

Be aware that an IOS upgrade from 12.2(58)SE to any 15.X will also include a mandatory bootstrap (aka microcode) upgrade.  All-in-all, it will take approximately 25 minutes to upgrade.  So don't be alarmed or soil-your-pants.  Make sure you arrange for a 45 minute downtime.
