Step 1: Replace the M20 Router Craft Interface

Action

To remove the M20 router craft interface, follow these steps:

1. Attach an electrostatic discharge (ESD) wrist strap to your bare wrist, and connect the wrist strap to one of the two ESD points on the chassis.
2. Unscrew the thumbscrews on the left and right sides of the card carrier to unseat the craft interface from the midplane.
3. Flip the ends of the two extractor clips, which are adjacent to the thumbscrews, toward the outside edges of the router.
4. Grasp both sides of the craft interface and slide it about three-quarters of the way out of the router.
5. Move one of your hands underneath the craft interface to support it, and slide the craft interface completely out of the chassis.
