Online Insertion and Removal Chapter 5 Installing and Removing a SIP 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 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. Enter the show facility-alarm status command. The following example shows a critical alarm that is generated when a SPA is removed from the system: Router# show facility-alarm status System Totals Critical: 1 Major: 0 Minor: 0 Source Severity Description [Index] ------ -------- subslot 1/1 CRITICAL Active Card Removed OIR Alarm [0] Note A critical alarm "Active Card Removed OIR Alarm" is generated even if a SPA is removed after performing graceful deactivation. 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 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. Cisco ASR 1000 Series Aggregation Services Routers SIP and SPA Hardware Installation Guide 5-6 OL-14126-12

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 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.
Enter the
show facility-alarm status
command. The following example shows a critical alarm that is
generated when a SPA is removed from the system:
Router#
show facility-alarm status
System Totals
Critical: 1
Major: 0
Minor: 0

subslot 1/1
CRITICAL
Active Card Removed OIR Alarm [0]
Note
A critical alarm "Active Card Removed OIR Alarm" is generated even if a SPA is removed after
performing graceful deactivation.
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 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.
