Handling a SIP
Online Insertion and Removal
The Cisco 7600 series router supports online insertion and removal (OIR) of the SPA interface processor
(SIP) or SPA services card (SSC), in addition to each of the shared port adapters (SPAs). Therefore, you
can remove a SIP or SSC with its SPAs still intact, or you can remove a SPA independently from the SIP
or SSC, leaving the SIP or SSC installed in the router.
This section includes the following topics on OIR support:

Note
For simplicity, any reference to “SIP” in this section also applies to the SSC.
Preparing for Online Removal of a SIP or SSC
The Cisco 7600 series router supports OIR of the SIP and the SSC. 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
no power enable module
command, the
Cisco 7600 series router does support removal of the SIP without deactivating it first. If you plan to
remove a SIP, you can deactivate the SIP first, using the
no power enable module
global configuration
command. 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.
