Chapter 5 Installing and Removing a SIP
Online Insertion and Removal
Although graceful deactivation of a SIP is recommended using the hw-module slot stop command, the
Cisco ASR 1000 Series Routers support the removal of the SIP without deactivating it first. If you plan
to remove a SIP, 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.
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 SIPs and
SPAs” section on page 2-3.
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 Router.
For example, consider the case where you remove a SIP from the Cisco ASR 1000 Series Router 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 Router, the SPAs 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:
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 SIP chassis slot number
where the SIP is installed.
• stop—Deactivates the SIP and places it in reset
mode.
Command Purpose
Router(config)# hw-module slot
slot-number start
Activates the SIP in the specified slot and its installed
SPAs, where:
• slot-number—Specifies the SIP chassis slot number
where the SIP is installed.
• start—Activates the SIP and removes it from reset
mode.
