Chapter 5 Installing and Removing a SIP
Online Insertion and Removal
Note
If you are preparing for an OIR of a SPA, it is not necessary to independently shut down each of the
interfaces prior to deactivation of the SPA. The
hw-module subslot shutdown
command automatically
stops traffic on the interfaces and deactivates them along with the SPA in preparation for OIR. In similar
fashion, you do not need to independently restart any interfaces on a SPA after OIR of a SPA or SIP.
To deactivate a SPA and all of its interfaces prior to removal of the SPA, use the following command
in
global configuration mode:
For more information about chassis slot and SIP subslot numbering, refer to the “Identifying Slots and
Subslots for SIPs, SSCs, and SPAs” section in this guide.
Reactivating a SPA
Note
You do not need to reactivate a SPA after an OIR of either the SIP or a SPA if you did not deactivate the
SPA prior to removal. If the router is running, then the SPAs automatically start upon insertion into the
SIP or with insertion of a SIP into the router.
If you deactivate a SPA using the
hw-module subslot shutdown
global configuration command and
need to reactivate it without performing an OIR, you need to use the
no hw-module subslot shutdown
global configuration command to reactivate the SPA and its interfaces.
