Installing an MX960 MPC
An MPC installs vertically in the front of the router. The MPCs are hot-insertable and hot-removable. A fully configured MPC can weigh up to 18.35 lb (8.3 kg). Be prepared to accept its full weight.
To install an MPC (see Figure 1):
- Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end of the strap to an ESD point.
- Place the MPC on an antistatic mat.
- Take each MIC to be installed in the replacement MPC out of its electrostatic bag, and identify the slot on the MPC where it will be connected.
- Verify that each fiber-optic MIC has a rubber safety cap covering the MIC transceiver. If it does not, cover the transceiver with a safety cap.
- Install each MIC into the appropriate slot on the MPC.
- Locate the slot in the card cage in which you plan to install the MPC.
- Orient the MPC so that the faceplate faces you.
- Lift the MPC into place, and carefully align the sides
of the MPC with the guides inside the card cage.
When the MPC is out of the chassis, do not hold it by the ejector handles, bus bars, or edge connectors. They cannot support its weight.
- Slide the MPC all the way into the card cage until you feel resistance.
- Grasp both ejector handles, and rotate them clockwise simultaneously until the MPC is fully seated.
- If any of the MICs on the MPC connect to fiber-optic cable,
remove the rubber safety cap from each transceiver and cable.
Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected to a transceiver emit laser light that can damage your eyes.
- Insert the appropriate cable into the cable connector
ports on each MIC on the MPC. Secure the cables so that they are not
supporting their own weight. Place excess cable out of the way in
a neatly coiled loop, using the cable management system. Placing
fasteners on a loop helps to maintain its shape.
Do not let fiber-optic cables hang free from the connector. Do not allow the fastened loops of a cable to dangle, which stresses the cable at the fastening point.
Avoid bending a fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.
- Use one of the following methods to bring the MPC online:
Press and hold the corresponding MPC online button on the craft interface until the green
OK/FAILLED next to the button lights steadily, in about 5 seconds.
Issue the following CLI command:
user@host>request chassis fpc slot slot-number online
For more information about the command, see the CLI Explorer.
OK/FAILLED lights steadily, wait at least 30 seconds before removing the MPC again, removing an MPC from a different slot, or inserting an MPC in a different slot.
