Removing SCBs

The device can have two SCBs. They are located horizontally on the bottom front of the chassis in the slots marked 0 and 1. Each SCB weighs approximately 9.6 lb (4.4 kg).

Caution: Before removing or replacing any component, ensure you are operating the ejector handles properly and they are stored correctly on all components.

To remove the SCBs, follow this procedure for each SCB (see Figure 73):

  1. Place an electrostatic bag or antistatic mat on a flat, stable surface.
  2. 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.
  3. Loosen the captive screws on the ejector handles on both sides of the SCB faceplate.
  4. Simultaneously rotate the ejector handles counterclockwise to unseat the SCB.
  5. Grasp the ejector handles and slide the SCB about halfway out of the chassis.
  6. Place one hand underneath the SCB to support it and slide it completely out of the chassis. Place it on the antistatic mat.

    Caution: Do not stack hardware components on one another after you remove them. Place each component on an antistatic mat resting on a stable, flat surface.

  7. Repeat the procedure for the second SCB.
