Hi,

Basically you can treat those as Line Cards in multy slot chassis routers like GSR or ASR.

shared port adapters (SPAs) and SPA interface processors (SIPs)

SIP is bigger card which is installed in chassis and it has several bays for SPAs. You can select different flavors of SPAs based on your business needs - e.g. SPA with copper or SFP port, supporting particular speeds, etc.

So these are like a line cards in 6k.
