Handling a SIP
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.
This section includes the following topics on OIR support:

Preparing for Online Removal of a SIP
The Cisco ASR 1000 Series Routers support OIR of the SIP. To do this, you can power down a SIP
(which automatically deactivates any installed SPAs) and remove the SIP with the SPAs still intact.
Although graceful deactivation of a SIP is preferred using the
hw-module slot stop
command, the Cisco
ASR 1000 Series Routers support removal of the SIP without deactivating it first. If you plan to remove
a SIP, you can deactivate the SIP first, using the
hw-module slot stop
command in global configuration
mode. When you deactivate a SIP using this command, it automatically deactivates each of the SPAs
that are installed in that SIP. Therefore, it is not necessary to deactivate each of the SPAs prior to
deactivating the SIP.
Either a blank filler plate or a functional SPA should reside in every subslot of a SIP during normal
operation.
