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 describes the SPA interface processor (SIP) that is supported on the Cisco CRS-1 router and contains the following sections:
A SIP is a type of PLIM that provides data interfaces for the routing system through the installed shared port adapters (SPAs). The SIP mates with its associated modular services card (MSC) through the chassis midplane. Each available SPA provides different interface types and port densities, as described in the chapter Overview: Cisco CRS Shared Port Adapters.
The below table shows a summary description of the SIP that is supported on the Cisco CRS-1 router.
Note | The Description column indicates the aggregate bandwidth supported by the SIP across all subslots—not for each SPA subslot. |

The following sections describe SIP, SPA, and interface numbering:
A SIP can be installed in PLIM slots 0 through 15 on the Cisco CRS-1 router 16-slot line card chassis and PLIM slots 0 through 7 on the Cisco CRS-1 router 8-slot line card chassis. Figure 2 and the figure below show the slot numbering on the front (PLIM side) of the line card chassis.
For additional information about the slot locations of PLIMs and their associated modular services cards (MSCs), see Cisco CRS Carrier Routing System 16-Slot Line Card Chassis System Description or Cisco CRS Carrier Routing System 8-Slot Line Card Chassis System Description . Both documents are available online from the specific chassis hardware documentation links at the following URL:
The Cisco CRS-1 SIP-800 accepts six single-width SPAs. The figure below shows a Cisco CRS-1 SIP-800 with two 4-Port OC-3c/STM-1 POS SPAs installed in subslots 0 and 3.
Note | Subslots 0, 1, and 3 can provide up to 20 Gbps of capacity, as can subslots 2, 4, and 5. Take care not to install SPAs that require more than 20 Gbps of capacity in each group of subslots so as not to oversubscribe the card. See the Bandwidth Oversubscription section in the Overview: Cisco CRS-1 Shared Port Adapters chapter for more information. |
The figure below and Figure 2 illustrate the SPA subslot locations on the Cisco CRS-1 SIP-800. The subslot labels are located inside the SPA subslot and are only visible when the SPA is not installed.

SPAs in the Cisco CRS-1 router running Cisco IOS XR Software Release 3.4.1 use an addressing format that specifies the physical location of the SIP, SPA, and interface. The interface address format is rack /slot /subslot /port , where:
