Removing A Line Card - Cisco ASR 9000 Series Installation Manual

Removing and Installing a Line Card
When installing a line card, always fully tighten both captive installation screws to ensure that the card
Caution
is correctly seated in the backplane connector. A card that is only partially seated in the backplane might
not operate properly, even if it boots.
•
The router may indicate a hardware failure if you do not follow proper procedures. Remove or insert only
Caution
one line card at a time. Allow at least 15 seconds for the router to complete the preceding tasks before
removing or inserting another line card.
After removing and inserting a line card into the same slot, allow at least 60 seconds before removing or
inserting another line card.
•
When you remove a line card, always use the ejector levers to ensure that the connector pins disconnect
Caution
from the backplane in the sequence expected by the router. Any card that is only partially connected to
the backplane can halt the router.
When you install a line card, 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. If a card is only partially seated in the
backplane, the router hangs and subsequently crashes.
To avoid damaging card mechanical components, never carry an RSP or line card by the captive
Caution
installation screws or ejector levers. Doing so can damage these components and cause card insertion
problems.

After you reinstall a line card, the router automatically downloads the necessary software from the
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.
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.
