Online Insertion and Removal
The Cisco ASR 1000 Series Routers support online insertion and removal (OIR) of the SPA interface
processor (SIP), in addition to each of the shared port adapters (SPAs). Therefore, you can remove a SIP
with its SPAs still intact, or you can remove a SPA independently from the SIP, leaving the SIP installed
in the router.

Preparing for Online Removal of a SIP

The Cisco ASR 1000 Series Routers support OIR of the SIP. To perform an OIR, power down a SIP
which automatically deactivates any installed SPAs and remove the SIP with the SPAs still intact.
If SIP-40 is installed with the bandwidth value greater than 11.2G and if SIP-40 is replaced with SIP-10
Note
then the bandwidth of SIP-10 is reset to its default maximum bandwidth of 11.2G. An informational
message indicating "Setting input bandwidth to ESI max bandwidth: 11199896" is displayed on the
console. This message is displayed when SIP-40 is downgraded to SIP-10 from Cisco IOS XE Release
3.1.0S onwards.
