One screw on each side of the NPC to secure

NPC installation and removal hardware
Thumb screws and levers used to install
and remove the NPC. There are thumb screws and double-lever release latches
on each side of the card. Each inner lever contains a micro-switch
and when you simultaneously pull both inner levers outward to release
the outer ejector levers, the NPC will power off. Only move these
levers if you intend to remove the card.
