Preparing for Online Insertion and Removal of a SPA
The Cisco ASR 1000 Series Aggregation Services Routers support online insertion and removal (OIR) of the
SIP, in addition to each of the 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.
This means that a SIP can remain installed in the router with one SPA remaining active, while you remove
another SPA from one of the SIP subslots. If you are not planning to immediately replace a SPA into the SIP,
then be sure to install a blank filler plate in the subslot. The SIP should always be fully installed with either
functional SPAs or blank filler plates.
For more information about activating and deactivating SPAs in preparation for OIR, see the
the
Troubleshooting the SIP
chapter.
