Introduction to SIPs and SPAs
SIPs and SPAs are a new carrier card and port adapter architecture used to increase 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.

SPA Interface Processors
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:
• 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 router fully populated either with functional
SPAs in all subslots, or with a blank filler plate (SPA-BLANK=) inserted in all empty subslots.
Master Indicates the master Service Control module
• Steady green — Master Service Control module
• Unlit — Slave Service Control module
Mng interface The Mng interface LEDs indicate the operational status of the Cisco SCE8000
out-of-band LAN-based management port, as follows:
• Link/Active
Steady green — Port link is up
Flashing green — Activity on the port link
Unlit — Port link is down
• Speed
Unlit — Port is set to 10Mbps
Steady green — Port is set to 100 Mbps
Steady amber — Port is set to 1000 Mbps
On a slave SCE8000-SMC_E module (in the second slot), this LED is always off.
