Online Insertion and Removal of a SPA
The Cisco 10000 series router supports OIR of a SPA independently of removing the SIP. 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.
The interface configuration is retained (recalled) if a SIP or SPA is removed and then replaced with one
of the same type.
If you are planning to remove a SIP along with its SPAs, then you do not need to follow the instructions
in this section. To remove a SIP, see
Chapter 5, “Installing and Removing a SIP”.
Deactivating a SPA
Although graceful deactivation of a SPA is preferred using the hw-module subslot shutdown command,
the Cisco 10000 series router does support removal of the SPA without deactivating it first. Before
deactivating a SPA, ensure that the SIP is seated securely into the slot before pulling out the SPA itself.
If you are preparing for an OIR of a SPA, there are no standard interfaces to be shut down prior to
deactivation of the SPA. The hw-module subslot shutdown command automatically stops traffic on the
Gigabit Ethernet interfaces and deactivates them along with the SPA in preparation for OIR. In similar
fashion, you do not need to independently restart any Gigabit Ethernet interfaces on a SPA after OIR of
a SPA or SIP.
Note You do not need to shut down a SPA if you are removing it and replacing it with the same exact model
of SPA in an online insertion and removal (OIR) operation. However, you must shut down a SPA and
preprovision the line card slot whenever you are replacing a SPA with a different model of SPA.
To deactivate a SPA and all of its interfaces prior to removal of the SPA, use the following command in
global configuration mode:
