The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter provides an introduction to SPA interface processors (SIPs) and shared port adapters (SPAs). It includes the following sections:
For software configuration information for the various SIPs and SPAs that are supported on the Cisco CRS router, refer to Cisco IOS XR Interface and Hardware Component Configuration Guide at the following URL:
For information on specific Cisco IOS XR software commands, refer to Cisco IOS XR Interface and Hardware Component Command Reference at the following URL: http://www.cisco.com/c/en/us/support/ios-nx-os-software/ios-xr-software/products-command-reference-list.html
SIPs and SPAs comprise a carrier card and port adapter architecture that 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.
The following list describes some of the general characteristics of a SIP:
The following list describes some of the general characteristics of a SPA:
For a list of the SPAs supported in the Cisco CRS router, see the SPA Summary section in the Cisco CRS-1 Shared Port Adapters chapter.
Note | For more information about the introduction of support for different SIPs and SPAs, refer to Cisco IOS XR Interface and Hardware Component Configuration Guide . |
Some SPAs implement small form-factor pluggable (SFP or XFP1) optical transceivers to provide network connectivity. An SFP module is a fiber-optic transceiver device that mounts in the front panel to provide network connectivity.
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. A check is run every time an SFP or XFP module is inserted into a SPA, and only those modules that pass this check are usable. |
The table below shows the types of optics modules that have been qualified for use with the SPAs supported on the Cisco CRS router, and the first software release that supports these optics:
