Chapter: SIP and SPA Product Overview
SIP and SPA Product Overview
This chapter provides an introduction to modular services cards (SIPs) and shared port adapters (SPAs). It includes the following sections:
•
Introduction to SIPs and SPAs
For more hardware details for the specific SIP and SPAs that are supported on the Cisco 12000 series router, refer to the companion publication, Cisco 12000 Series Router SIP and SPA Hardware Installation Guide.
Introduction to SIPs and SPAs
SIPs and SPAs are a new carrier card and port adapter architecture to increase 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
The following list describes some of the general characteristics of a 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.
•A SIP can contain two or more subslots, which are used to house one or more SPAs. The SPA provides interface ports for network connectivity.
•During normal operation the SIP should reside in the router fully populated either with functional SPAs in all subslots, or with a blank filler panel inserted in any empty subslots.
•SIPs support online insertion and removal (OIR) while SPAs are inserted in their subslots.
Shared Port Adapters
The following list describes some of the general characteristics of a SPA:
•A SPA is a modular type of port adapter that inserts into a subslot of a compatible SIP carrier card to provide network connectivity and increased interface port density. A SIP can hold one or more SPAs, depending on the SIP type.
•SPAs are available in the following sizes, as shown in Figure 2-1 and Figure 2-2:
–Single-height SPA—Inserts into a single SIP subslot.
–Double-height SPA—Inserts into two single, vertically aligned SIP subslots.

•Each SPA provides a certain number of connectors, or ports, that are the interfaces to one or more networks. These interfaces can be individually configured within the Cisco IOS command-line interface (CLI).
•Either a blank filler panel or a functional SPA should reside in every subslot of an SIP during normal operation.
•SPAs support online insertion and removal (OIR). They can be inserted or removed independently from the SIP. OIR of a SIP with installed SPAs is also supported.
SFP and XFP Optics Modules
For more detailed information about the SFP and XFP optics modules, please refer to the applicable SPA section in the Cisco 12000 Series Router SIP and SPA Hardware Installation Guide.
