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. • SIPs support online insertion and removal (OIR) with SPAs inserted in their subslots. SPAs also support OIR and can be inserted or removed independently from the SIP. Note Fully populate all slots and subslots with blank filler plates or functional SPAs for maximum efficiency of the cooling system.

Introduction to SIPs and SPAs
Cisco ASR 1000 Series Aggregation Services Routers SIPs and SPAs are a carrier card and port adapter
architecture that increases modularity, flexibility, and density across Cisco routers for network
connectivity. This section describes the SIPs 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 subslots, 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.
•
SIPs support online insertion and removal (OIR) with SPAs inserted in their subslots. SPAs also
support OIR and can be inserted or removed independently from the SIP.
Note
Fully populate all slots and subslots with blank filler plates or functional SPAs for maximum efficiency
of the cooling system.
