Attach an ESD grounding strap to your bare wrist, and connect the other end of the strap to an ESD grounding point.
Carefully align the sides of the Switch Control Board with the guides inside the chassis.
Slide the Switch Control Board into the chassis until you feel resistance, carefully ensuring that it is correctly aligned.
Grasp both ejector handles, and rotate them simultaneously clockwise until the Switch Control Board is fully seated.
Place the ejector handles in the proper position, horizontally and toward the center of the board.

Check the LEDs on the Switch Control Board faceplate to verify that it is functioning normally.
- The green OK/FAIL LED should light steadily a few minutes after the Switch Control Board is installed.
- If the OK/FAIL LED is red, remove and install the Switch Control Board again. If the OK/FAIL LED still lights steadily, the Switch Control Board is not functioning properly. Contact your customer support representative.

Check the status of the Switch Control Board using the show chassis environment cb command:
