A SIP contains one or more subslots, which are used to house one or more SPAs. The SPA provides
interface ports for network connectivity. Cisco ASR14K-20XGE-FL SIP has two subslots to house
upto two SPAs.
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).
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 and the SPA size.
SPAs are available in the following sizes:
Single-height SPA—Inserts into one SIP subslot.
–
Double-height SPA—Inserts into two single, vertically aligned SIP subslots.
–
The Cisco ASR14K-20XGE-FL SIP supports two flexible, single-height SPAs, as shown in
Figure

Subslot Numbering for SPAs—Front View (SIP)
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 XR software
command-line interface (CLI).
Either a blank filler plate (SPA-BLANK=) 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.
