Removing and Installing a Line Card
Note The installation and removal procedure for the ATM line card is different for the Cisco 12008 and Cisco 12012 routers than for the other Cisco 12000 series routers. Make sure you refer to the procedure that corresponds to your router chassis.
Caution To avoid erroneous failure messages, remove or insert only one line card at a time. After inserting or removing a line card, allow at least 15 seconds before removing or inserting another line card, so that the router can reinitialize and note the current configuration of all interfaces.
After removing and inserting a line card into the same slot, allow at least 60 seconds before removing or inserting another line card.
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.
