Replacing a Card (General)
NOTICE
Service-disruption hazard
A card reseat is service impacting if the card is currently carrying services. To discover if
any services are currently carried over a card, perform the procedure “Checking for
Services
on a Port” (p. 3-10). If there are services currently carried over the card, it may
be
best to wait for a maintenance window before reseating the card.
Cooling airflow is critically important for reliable transmission. Every slot in the subrack
requires a circuit pack (card) or circuit pack blank to ensure proper airflow. Do not
remove old cards until new cards are fully prepared for installation. New cards should be
installed within five minutes of old card removal in order to maintain proper airflow and
cooling for the other cards within the subrack.

4
Remove and cap all of the fibers connected to the card.

5
Verify that you have an unobstructed extraction path. Tie back any adjacent fibers that
may be impacted by the card extraction.

6
Unlock the card latch. Place a thumb or finger on the latch release/locking pin located
behind the latch cover and open the latch by lifting up and out. This will partially unseat
the card from the backplane.
