Deactivating A Spa - Cisco ASR 1000 Series Software Configuration Manual

Preparing for Online Removal of a SPA
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 the

Deactivating a SPA

Although graceful deactivation of a SPA is preferred using the hw-module subslot stop command in EXEC
mode, the Cisco Aggregation Services Router 1000 Series 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 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:
