Reinstalling the SCBs After Installing the MX240 Router with a Lift
To reinstall an SCB (see Figure 59 on page 181):
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.
2. Carefully align the sides of the SCB with the guides inside the chassis.
3. Slide the SCB into the chassis until you feel resistance, 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. To avoid blocking the visibility of the LEDs position the ejectors over the
PARK icon.
