Removing a Modular Line Card
If you are replacing a failed modular line card (MLC), remove the existing MLC first, then install the
new MLC in the same slot. To remove a MLC, use
Step 1
Attach an ESD-preventive wrist strap and follow its instructions for use.
Step 2
Disconnect and remove all interface cables from the ports; write down the current connections of the
cables to the ports on the MPAs and the MPA locations if you remove the MPA.
Step 3
Detach the cable-management bracket from the MLC.
Use a screwdriver to loosen the captive screw at each end of the MLC faceplate. (See callout 1 on
Figure
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.
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.
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.
When you remove a MLC, always use the ejector levers to ensure that the connector pins
disconnect from the backplane in the logical sequence expected by the router. Any card that
is only partially connected to the backplane can halt the router.
When you install a MLC, always use the ejector levers to ensure that the card is correctly
aligned with the backplane connector; the connector pins should make contact with the
backplane in the correct order, indicating that the card is fully seated in the backplane. A card
that is only partially seated in the backplane will cause the router to hang and subsequently
crash.
