Installed Modules on ISR 4331

[Matthew Martin]

Hello All,

Device: ISR4331/K9

I'm not familiar with "SM" slots on the ISR devices and I was wondering if someone might be able to tell me if there's anything plugged into the "SM 1" slot based off the show inventory command shown below?

I can see that NIM 1 has an FXO line card in it and NIM 2 has a FXS line card. But, I'm not sure if there's anything plugged into the "SM 1" of the ISR4331...?

Thanks in Advance,

Matt

Nothing is installed in the SM slot based on that output - just the built-in service module (SM) controller on the motherboard.

Here's a good visual reference:

Ok, thanks Marvin. Much appreciated.
