Preparing for Online Removal of a SIP
The Cisco ASR 1000 Series Routers support OIR of a SIP. To do this, you can power down a SIP (which
automatically deactivates any installed SPAs) and remove the SIP with the SPAs still intact.
Although graceful deactivation of a SIP is preferred using the hw-module slot stop command, the Cisco
ASR 1000 Series Routers do support removal of the SIP without deactivating it first. If you plan to
remove a SIP, you can deactivate the SIP first, using the hw-module slot stop command in global
configuration mode. When you deactivate a SIP using this command, it automatically deactivates each
of the SPAs that are installed in that SIP. Therefore, it is not necessary to deactivate each of the SPAs
prior to deactivating the SIP.
Note 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 ASR 1000 Series Aggregation Services Routers SIP and SPA Hardware Installation Guide.
Deactivating a SIP
To deactivate a SIP 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, see the “Identifying Slots and Subslots for the SIP
and SPAs” section on page 4-1.
Reactivating a SIP
If you did deactivate the SIP using the hw-module slot stop 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 Cisco ASR 1000 Series Routers.
For example, consider the case where you remove a SIP from the Cisco ASR 1000 Series Routers to
replace it with another SIP. You reinstall the same SPAs into the new SIP. When you enter the
hw-module slot start command on the Cisco ASR 1000 Series Routers, the SPAs automatically
reactivate with the new SIP.
Command Purpose
Router(config)# hw-module slot
slot-number stop
Shuts down any installed interfaces, and deactivates the
SIP in the specified slot, where:
• slot-number—Specifies the chassis slot number
where the SIP is installed.
• stop—Deactivates the SIP and places it in reset
mode.
