Removing and Installing a Line Card
The following sections describe the procedures for removing and installing line cards:
Note
Some of the procedures in the following sections use illustrations of a Cisco 12012 Internet Router to 
support the descriptions of removing and installing line cards. Although the card cages of Cisco 12000 
Series Routers differ, the designated use of slots and the process of installing and removing a line card 
are basically the same. Therefore, separate procedures and illustrations are not included in this 
publication.
Guidelines for Line Card Removal and Installation
Guidelines for line card removal and installation include the following:
Online insertion and removal (OIR) is supported, enabling you to remove and install line cards 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 line card. 
After you reinstall a line card, 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. 
Caution
The router may indicate a hardware failure if you do not follow proper procedures. Remove 
or insert only one line card at a time. Allow at least 15 seconds for the router to complete the 
preceding tasks before removing or inserting another line card.
After removing and inserting a line card into the same slot, allow at least 60 seconds before 
removing or inserting another line card.
Line cards have two ejector levers to release the card from its backplane connector. Use the levers 
when you are removing the line card and to seat the line card firmly in its backplane connector when 
you are installing the line card. The ejector levers align and seat the card connectors in the 
backplane.
