Chapter 1 SIP and SPA Product Overview
SIP and SPA Compatibility
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 subslot 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.
•
A single-height SPA inserts into one SIP subslot. (See
Figure 1-1
Slot Orientation for SPAs
Caution
SIP subslot 0 is not available on the Cisco ASR 1002 Router as that is the slot occupied by the integrated
Route Processor with native Gigabit Ethernet ports.
•
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 subslot of a 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 OIR with SPAs inserted in their subslots.
