Deactivating A Spa - Cisco ASR-1000-SIP10 Hardware Installation Manual

Chapter 5 Installing and Removing a SIP

Deactivating a SPA

Although graceful deactivation of a SPA is preferred using the hw-module subslot stop command in
EXEC mode, the Cisco ASR 1000 Series Routers 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, it is not necessary to independently shut down each of the
Note
interfaces prior to deactivation of the SPA. The hw-module slot stop command in EXEC mode
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.
Choosing the Mode of the hw-module subslot Command
You can deactivate a SPA and all of its interfaces by using the hw-module subslot command in one of
two modes:
•
•
To deactivate a SPA and all of its interfaces prior to removal of the SPA, use the following commands
in global configuration mode:

If you choose to use the hw-module subslot shutdown command in global configuration mode, you
change the configuration so that no matter how many times the router is rebooted, the SPA will not
boot. This command is useful when you need to shut down a SPA in a remote location and ensure
that it does not come back up if the router is rebooted.
If you choose to use the hw-module subslot stop command in EXEC mode, you cause the SPA to
gracefully shut down. However, the SPA will come up again when executing the hw-module
subslot start command.
