Note
Some of the procedures in the following sections use illustrations of a Cisco 12012 Router to support the
descriptions of removing and installing SIPs. Although the card cages of Cisco XR 12000 Series Routers
differ, the designated use of slots and the process of installing and removing a SIP are basically the same.
Therefore, separate procedures and illustrations are not included in this publication.
Guidelines for SIP Removal and Installation
Guidelines for SIP removal and installation include the following:
•
Online insertion and removal (OIR) is supported, enabling you to remove and install SIPs while the
router is operating. OIR is seamless to users on the network, maintains all routing information, and
ensures session preservation.
Note
With OIR, notifying the software or resetting the power is not required. However, you have the
option of using the shutdown command before removing a SIP.
•
After you reinstall a SIP, the router automatically downloads the necessary software from the route
processor (RP). Next, the router brings online only those interfaces that match the current
configuration and were previously configured as administratively up. You must configure all others
with the configure command.
