Installing an SCB

To install an SCB (see Figure 47):

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis. For more information about ESD, see Preventing Electrostatic Discharge Damage.
  2. Power off the device as described in Powering Off the Services Gateway.
  3. Carefully align the sides of the SCB with the guides inside the chassis.
  4. Slide the SCB into the chassis until you feel resistance, carefully ensuring that it is correctly aligned.
  5. Grasp both ejector handles and rotate them simultaneously clockwise until the SCB is fully seated.
  6. Place the ejector handles in the proper position, vertically and toward the center of the board.
  7. Power on the services gateway as described in Powering On an AC-Powered Services Gateway or Powering On a DC-Powered Services Gateway. The OK LED on the power supply faceplate should blink, then light steadily.
  8. To verify that the SCB is functioning normally, check the LEDs on its faceplate. The green OK/FAIL LED should light steadily a few minutes after the SCB is installed. If the OK/FAIL LED is red, remove and install the SCB again (see Removing an SCB and Installing an SCB). If the OK/FAIL LED still lights steadily, the SCB is not functioning properly. Contact your customer support representative.

    To check the status of the SCB:
