Troubleshooting the SIP
Preparing for Online Insertion and Removal of the SIP and SPAs
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.
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 stop command in global
configuration 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:
• 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 global configuration mode, you cause
the SPA to gracefully shut down. However, the SPA will come up again when executing the
hw-module subslot start command.
To deactivate a SPA and all of its interfaces prior to removal of the SPA, use the following commands in
global configuration mode:
