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

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.
