Reinstalling SCBs
To reinstall an SCB (see Figure 72 on page 196):
CAUTION: Before removing or replacing an SCB, ensure that the ejector handles are
stored vertically and pressed toward the center of the SCB.
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” on page 130.
2. Carefully align the sides of the SCB with the guides inside the chassis.
3. Slide the SCB into the chassis, carefully ensuring that it is correctly aligned.
4. Grasp both ejector handles and rotate them simultaneously clockwise until the
SCB is fully seated.
5. Place the ejector handles in their proper position, horizontally and toward the
center of the board.
