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 7600 series router 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.
