Introduction to the Cisco SCE8000 10GBE Platform
Introduction to SIPs and SPAs
SIPs and SPAs are a new carrier card and port adapter architecture used to increase modularity,
flexibility, and density for network connectivity. This section describes the SIPs and SPAs and provides
some guidelines for their use.

The SIP module supported by the Cisco SCE8000 chassis is the SCE8000-SIP.
The following list describes some of the general characteristics of a SIP:

Specifying the SIP Subslot Location for a SPA
Cisco SCE8000-SIP subslots begin their numbering with "0" and have a horizontal orientation.

A SIP is a carrier card that inserts into a slot in the chassis like a line card. It provides no network
connectivity on its own.
A SIP contains one or more subslots (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 SCE8000 chassis fully populated either with
functional SPAs in all subslots, or with a blank filler plate (SPA-BLANK=) inserted in all empty
subslots.
