Introduction to SIPs and SPAs
Shared Port Adapters
The SPA supported by the Cisco SCE8000-SIP is the 1-Port 10-Gigabit Ethernet SPA,
SPA-1X10GE-L-V2
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 subslot of a compatible SIP carrier card
to provide network connectivity and increased interface port density. The Cisco SCE8000-SIP can
hold up to four SPAs.
Since the interfaces are connected in subscriber/network pairs, either two or four SPAs must be
installed.
The supported SPA is a single-height SPAs, which inserts into one SIP subslot. (See

Each SPA provides a one 10GBE port, which is the interface to either subscriber or network traffic.
These interfaces can be individually configured using the Cisco command-line interface (CLI).
Either a blank filler plate or a functional SPA should reside in every subslot of an SIP during normal
operation to maintain cooling integrity. Blank filler plates are available in single-height form only.
Since the interfaces are connected in subscriber/network pairs, the SCE8000-SIP must be either
fully populated or have both the bottom bays covered with blank filler plates.
