Chapter 5 Installing and Removing a SIP
Online Insertion and Removal
Either a blank filler plate or a functional SPA should reside in every subslot of a SIP during normal
operation.
For more information about the recommended procedures for physical removal of the SIP, refer to the
Cisco 7600 Series Router SIP, SSC, and SPA Hardware Installation Guide.
Deactivating a SIP or SSC
To deactivate a SIP or SSC and its installed SPAs prior to removal of the SIP, use the following command
in global configuration mode:
For more information about chassis slot numbering, refer to the “Identifying Slots and Subslots for SIPs,
SSCs, and SPAs” section in this guide.
Reactivating a SIP or SSC
Once you deactivate a SIP or SSC, whether or not you have performed an OIR, you must use the
power
enable module
global configuration command to reactivate the SIP.
If you did not issue a command to deactivate the SPAs installed in a SIP, but you did deactivate the SIP
using the
no power enable module
command, then you do not need to reactivate the SPAs after an OIR
of the SIP. The installed SPAs automatically reactivate upon reactivation of the SIP in the router.
For example, consider the case where you remove a SIP from the router to replace it with another SIP.
You reinstall the same SPAs into the new SIP. When you enter the
power enable module
command on
the router, the SPAs will automatically reactivate with the new SIP.
To activate a SIP and its installed SPAs after the SIP has been deactivated, use the following command
in global configuration mode:
For more information about chassis slot numbering, refer to the “Identifying Slots and Subslots for SIPs,
SSCs, and SPAs” section in this guide.
Verifying Deactivation and Activation of a SIP or SSC
To verify the deactivation of a SIP or SSC, enter the
show module
command in privileged EXEC
configuration mode. Observe the Status field associated with the SIP that you want to verify.
