Removing the Application Card
To minimize the risk of data loss, ensure that all LEDs on the packet processing card are Off (extinguished)
Caution
and that SMCs have stopped blinking prior to removing the card from the chassis.
Step 3
Pull the ejector levers outward, firmly and straight, until the card is unseated from the chassis.
Step 4 Holding the card by its ejector levers, gently slide the card out of the chassis by pulling the card toward you.
Do not leave chassis slots uncovered for extended periods of time. This reduces airflow through the chassis
Caution
and could cause it to overheat. Make sure a card or a blanking panel is installed in every chassis slot at all
times.
