MX104 as an LNS

Hi Guys,

Still pretty new to Juniper here and especially new to using a Juniper device as an LNS.  

We've gone ahead and gone for an MX104 router with a 20x1GB MIC card. What I'm wondering is if we also need the MS-MIC card to allow inline services to function?

We've ordered the licenses but I'm starting to doubt we have the needed hardware?

Thanks
