For software configuration information for the SIPs and SPAs that are supported on the Cisco 10000 series router, refer to the Cisco 10000 Series Router SIP and SPA Software Configuration Guide.
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.
Shared Port Adapters
General characteristics of a SPA include:
•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 and the SPA size.
•SPAs are available in the following sizes:
–Half-height—Inserts into one SIP subslot.
–Full-height—Inserts into two horizontally aligned SIP subslots. The Cisco 10000 SIP-600 supports two full-height SPAs, specified as SPA 0 and SPA 1.
–Full-height, double-wide—Occupies four standard, half-height SIP subslots.
Figure 1-1 shows the slot orientation for the SPAs.

•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 using the Cisco IOS command-line interface (CLI).
•To maintain cooling integrity, either a blank filler plate (SPA-BLANK=) or a functional SPA must reside in each subslot of a SIP during normal operation. Blank filler plates are available in half-height form only.
•SPAs support online insertion and removal (OIR). They can be inserted or removed independently from the SIP. The SIP also supports OIR with SPAs inserted in their subslots.

Modular Optics Compatibility
Some SPAs implement small form-factor pluggable (SFP or XFP) optical transceivers to provide network connectivity. The SFP and XFP modules are fiber-optic transceiver devices that mount to the front panel to provide network connectivity.
Note SFP modules are optics modules with speeds lower than 10 gigabits per second (Gb/s); XFP modules are optics modules with speeds equal to or greater than 10 Gb/s.
Cisco Systems qualifies the SFP modules that can be used with SPAs.
Note The SPAs accept only the optics modules listed as supported in this document. Each time an SFP or XFP module is inserted into a SPA, a check is run. Only SFP and XFP modules that pass this check are usable.
Table 1-2 shows the types of optics modules that are qualified for use with a SPA.

Power Management
SPAs and SIPs consume chassis power; therefore, make sure the chassis is within the power budget on the Cisco 10000 series router. Table 1-3 shows the maximum power consumption, in watts, for the SIP and SPAs.
