To Remove an Interface Card
Loosen the screws on the right and left side of the interface card until they spin freely.
Depress the red buttons on the inside of the attachment levers until they click and lock into place. The Hot Swap status LED should now be lit.
Do not remove the Interface Card while Hot Swap LED is ON. When the Hot Swap LED is on, UX is in the process of shutting
down system resources associated with the interface card.
Wait until the Hot Swap LED turns off. When the LED turns off, it is safe to remove the card from the chassis.
Grip the inside of the attachment levers and push toward the outside edges of the card.
Carefully pull the card free of the chassis.
