Introduction to SIPs and SPAs
SIP and SPA carrier card and port adapter architecture increases modularity, flexibility, and density
across Cisco Systems routers for network connectivity. This section describes the SIPs and SPAs and
provides some guidelines for their use.
SPA Interface Processors
This section describes general characteristics of a SPA interface processor (SIP). A SIP:
•
Is a carrier card that inserts into a router slot like a line card. It provides no network connectivity on
its own.
•
Contains one or more subslots, which are used to house one or more SPAs. The SPA provides
interface ports for network connectivity.
•
During normal operation, should reside in the router fully populated with either: functional SPAs in
all subslots, or with a blank filler plate (SPA-BLANK=) inserted in all empty subslots.
•
Support online insertion and removal (OIR). They can be inserted or removed independently from
the SIP.
