Chapter 5 Installing and Removing a SIP Online Insertion and Removal Deactivating a SPA Although graceful deactivation of a SPA is preferred using the hw-module subslot shutdown command, the Cisco 7600 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. 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 shutdown command 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. To deactivate a SPA and all of its interfaces prior to removal of the SPA, use the following command in global configuration mode: Command Router(config)# hw-module subslot slot/subslot shutdown [powered | unpowered] Purpose Deactivates the SPA in the specified slot and subslot of the SIP, where: • slot-Specifies the chassis slot number where the SIP is installed. • subslot-Specifies subslot number on a SIP where a SPA is installed. • powered-(Optional) Shuts down the SPA and all of its interfaces, and leaves them in an administratively down state with power enabled. This is the default state. • unpowered-(Optional) Shuts down the SPA and all of its interfaces, and leaves them in an administratively down state without power. For more information about chassis slot and SIP subslot numbering, refer to the "Identifying Slots and Subslots for SIPs, SSCs, and SPAs" section in this guide. Reactivating a SPA Note You do not need to reactivate a SPA after an OIR of either the SIP or a SPA if you did not deactivate the SPA prior to removal. If the router is running, then the SPAs automatically start upon insertion into the SIP or with insertion of a SIP into the router. If you deactivate a SPA using the hw-module subslot shutdown global configuration command and need to reactivate it without performing an OIR, you need to use the no hw-module subslot shutdown global configuration command to reactivate the SPA and its interfaces.

Installing and Removing a SIP
Online Insertion and Removal
Deactivating a SPA
Although graceful deactivation of a SPA is preferred using the
hw-module subslot shutdown
command,
the Cisco 7600 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.
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 shutdown
command 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.
To deactivate a SPA and all of its interfaces prior to removal of the SPA, use the following command
in
global configuration mode:
For more information about chassis slot and SIP subslot numbering, refer to the “Identifying Slots and
Subslots for SIPs, SSCs, and SPAs” section in this guide.
Reactivating a SPA
Note
You do not need to reactivate a SPA after an OIR of either the SIP or a SPA if you did not deactivate the
SPA prior to removal. If the router is running, then the SPAs automatically start upon insertion into the
SIP or with insertion of a SIP into the router.
If you deactivate a SPA using the
hw-module subslot shutdown
global configuration command and
need to reactivate it without performing an OIR, you need to use the
no hw-module subslot shutdown
global configuration command to reactivate the SPA and its interfaces.
Command
Purpose
Router(config)#

Deactivates the SPA in the specified slot and subslot of
the SIP, where:
•
slot—
Specifies the chassis slot number where the
SIP is installed.
•
subslot
—Specifies subslot number on a SIP where
a SPA is installed.
•

—(Optional) Shuts down the SPA and all
of its interfaces, and leaves them in an
administratively down state with power enabled.
This is the default state.
•
