Introduction to SIPs, SSCs, and SPAs
SIPs, SSCs, 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, SSCs, 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 contains one or more bays, 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 bays, or with a blank filler plate (SPA-BLANK=) inserted in all empty bays.
•SIPs support online insertion and removal (OIR) with SPAs inserted in their bays. SPAs also support OIR and can be inserted or removed independently from the SIP.
SPA Services Cards
The following list describes some of the general charateristics of an SSC:
•An SSC is a carrier card that inserts into a router slot like a line card. It provides no network connectivity.
•An SSC provides one or more bays, which are used to house one or more SPAs. The supported SPAs do not provide interface ports for network connectivity, but provide certain services.
•During normal operation the SSC should reside in the router fully populated either with functional SPAs in all bays, or with a blank filler plate (SPA-BLANK=) inserted in all empty bays.
•SSCs support online insertion and removal (OIR) with SPAs inserted in their bays. SPAs also support OIR and can be inserted or removed independently from the SSC.
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 bay 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.
•Some SPAs provide services rather than network connectivity, and insert into bays of compatible SSCs. For example, the IPSec VPN SPA provides services such as IP Security (IPSec) encryption/decryption, generic routing encapsulation (GRE ), and Internet Key Exchange (IKE) key generation.
•SPAs are available in the following sizes, as shown in Figure 2-1 and Figure 2-2:
–Single-height SPA—Inserts into one SIP bay.
–Double-height SPA—Inserts into two single, vertically aligned SIP bays.
Figure 2-1 Single-Height and Double-Height SPA Sizes
Figure 2-2 Horizontal and Vertical Chassis Slot Orientation for 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).
•Either a blank filler plate or a functional SPA should reside in every bay of an SIP during normal operation to maintain cooling integrity. Blank filler plates are available in single-height form only.
•SPAs support online insertion and removal (OIR). They can be inserted or removed independently from the SIP. SIPs also support online insertion and removal (OIR) with SPAs inserted in their bays.

Certain restrictions apply while using the SIP-600 and the IPSec VPN SPA on the same chassis:
•The SIP-600 should not be installed in the same chassis with an IPSec VPN SPA when running SXF.
•The SIP-600 is not supported in 12.2(33)SRA.
•Starting with 12.2(33)SRB, the SIP-600 and IPSec VPN SPA can be present in the same chassis. However, SIP-600 subinterfaces cannot be used when VPN crypto-connect mode is configured.

Modular Optics Compatibility
Some SPAs implement small form-factor pluggable (SFP) optical transceivers to provide network connectivity. An SFP module is a transceiver device that mounts into the front panel to provide network connectivity.
Cisco Systems qualifies the SFP modules that can be used with SPAs.
Note The SPAs will only accept the SFP modules listed as supported in this document. An SFP check is run every time an SFP module is inserted into a SPA and only SFP modules that pass this check will be usable.
Table 2-7 shows the types of optics modules that have been qualified for use with a SPA.
