When you perform a graceful shutdown on a SIP, cefcFRUInserted and cefcFRURemoved traps are not
generated.
Note
• After you reinstall a SIP, 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 SIP at a time. Allow at least 15 seconds for the router to complete the preceding tasks before removing
or inserting another SIP.
Caution
• SIPs have two ejector levers to release the card from its backplane connector. Use the levers when you
are removing the SIP and to seat the SIP firmly in its backplane connector when you are installing the
SIP. The ejector levers align and seat the card connectors in the backplane.
When you remove a SIP, 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 SIP, 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.
Caution
Removing a SIP
If you are replacing a failed SIP, remove the existing SIP first, then install the new SIP in the same slot. To
remove a SIP, follow these steps:
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; note the current connections of the cables to the ports on the
SPAs, if any, and SPA locations if you remove the SPAs.
Step 3 Detach the SIP cable-management bracket from the SIP.
Step 4 Use a screwdriver to loosen the captive screw at each end of the SIP faceplate.
