Note
When a MLC is moved to a new slot, the system recognizes the new interfaces but leaves them in the shutdown
state until you configure them and change their state to up. When a new MLC is inserted into a slot where a
MLC previously resided, provided you reinstall the modular port adapters (MPAs) and interfaces and their
cables in the same configuration as in the previous MLCs, the interfaces will come up in the same state as
though you reinserted the old MLC.
The following sample display shows the events logged by the system as you insert a new MLC in module slot
4.

Use the following procedure to verify that the MLC is installed correctly:
1. Observe the console display messages and verify that the system discovers the MLC, while the system
reinitializes each interface, as follows:
2. Verify that the STATUS LED on the MPA goes on (is green) and remains on after the reinitialization is
complete. If the STATUS LED remains on, proceed to Step 5. If the STATUS LED does not remain on,
proceed to Step 3.
3. If the STATUS LED on a MPA fails to go on, the MPA or the MLC might not be fully seated.
Type of Information Provided
Network link status, register contents, and controller
chip errors.
Line status and data link protocol status for a particular
MPA port. Statistics about data traffic sent and received
by the port.
MPA type in that slot, number of ports, hardware
revision, part number, and EEPROM contents.
Cisco IOS XR software version and boot images.
• If you installed a new MLC, the STATUS LED should be on (green). The system should recognize
all new interfaces but leave them configured as down.
• If you replaced a MLC, the STATUS LED should be on (green). The interfaces will come up in the
same state as though you reinserted the old MLC.
• Remove the MPA from the MLC.
