Installing an MX960 Switch Control Board
- 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:
