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.

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.

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.
