Figure 70: Reinstalling an SCB
Reinstalling the DPCs After Installing the MX240 Router without a Lift
To reinstall a DPC (see Figure 71 on page 194):
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. Place the DPC on an antistatic mat or remove it from its electrostatic bag.
3. Identify the slot on the router where it will be installed.
4. Verify that each fiber-optic transceiver is covered by a rubber safety cap. If it does not,
cover the transceiver with a safety cap.
5. Orient the DPC so that the faceplate faces you.
6. Lift the DPC into place and carefully align the sides of the DPC with the guides inside
the card cage.
7. Slide the DPC all the way into the card cage until you feel resistance.
8. Grasp both ejector handles and rotate them clockwise simultaneously until the DPC
is fully seated.
