a SIP with its SPAs still intact, or you can remove a SPA independently from the SIP, leaving the SIP installed
in the router.
This section includes the following topics on OIR support:
Preparing for Online Removal of a SIP
The Cisco Aggregation Services Router 1000 Series 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.
If SIP-40 is installed with the bandwidth value greater than 11.2G and if SIP-40 is replaced with SIP-10
then the bandwidth of SIP-10 is reset to its default maximum bandwidth of 11.2G. An informational
message indicating “Setting input bandwidth to ESI max bandwidth: 11199896” is displayed on the console.
This message is displayed when SIP-40 is downgraded to SIP-10 from Cisco IOS XE Release 3.1.0S
onwards.
Note
Although graceful deactivation of a SIP is preferred using the hw-module slot stop command, the Cisco
Aggregation Services Router 1000 Series 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.
Either a blank filler plate or a functional SPA should reside in every subslot of a SIP during normal
operation.
Note
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:
PurposeCommand
Shuts down installed interfaces and deactivates the
SIP in the specified slot.
• slot-number—Specifies the chassis slot number
where the SIP is installed
• stop—Deactivates the SIP and places it in reset
mode
Router(config)# hw-module slot slot-number stop
For more information about chassis slot numbering, see the “Identifying Slots and Subslots for the SIPs and
SPAs” section in the Configuring the SIP chapter.
