Guidelines for Modular Line Card Removal and Installation
• Online insertion and removal (OIR) is supported, enabling you to remove and install MLCs while the
router is operating. OIR is seamless to users on the network, maintains all routing information, and
ensures session preservation.
With OIR, notifying the software or resetting the power is not required. However, you have the option of
using the hw-module loc rack/slot/CPU0 maint command before removing a MLC.
Note
• After you reinstall a MLC, the router automatically downloads the necessary software from the Route
Switch Processor (RSP). 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.
The router may indicate a hardware failure if you do not follow proper procedures. Remove or insert only
one MLC at a time. Allow at least 15 seconds for the router to complete the preceding tasks before removing
or inserting another MLC.
Caution
• MLCs have two ejector levers to release the card from its backplane connector. Use the levers when you
are removing the MLC and to seat the MLC firmly in its backplane connector when you are installing
the ML. The ejector levers align and seat the card connectors in the backplane.
