Installing a Cable on an MX480 DPC, MPC, MIC, or PIC
To install a cable:
- Have ready a length of the type of cable used by the DPC, MPC, MIC, or PIC. For cable specifications, see the MX Series 3D Universal Edge Routers Line Card Guide.
- If the cable connector port is covered by a rubber
safety plug, remove the plug.
Warning: Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable connected to a transceiver emit laser light that can damage your eyes.
Caution: Do not leave a fiber-optic transceiver uncovered except when inserting or removing cable. The safety cap keeps the port clean and prevents accidental exposure to laser light.
- Insert the cable connector into the cable connector port on the component faceplate.
- Arrange the cable in the cable management brackets to prevent
it from dislodging or developing stress points. Secure the cable so
that it is not supporting its own weight as it hangs to the floor.
Place excess cable out of the way in a neatly coiled loop. Placing fasteners on the loop helps to maintain its shape.
Caution: Do not let fiber-optic cable hang free from the connector. Do not allow fastened loops of cable to dangle, which stresses the cable at the fastening point.
Caution: Avoid bending 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.
- Insert the other end of the cable into the destination port.
- Repeat the previous steps for any additional cables.
- If the component is offline (its failure indicator
LED is lit), use one of the following methods to bring the it online:
- To bring a DPC or an MPC online:
- Press and hold the corresponding online button on the craft interface until the green OK LED next to the button lights steadily, in about 5 seconds.
- Issue the following CLI command:
user@host>request chassis fpc slot slot-number onlineFor more information about the command, see the Junos System Basics and Services Command Reference.
- To bring a PIC online:
- Press the PIC offline/online button until the PIC LED lights green. For a PIC installed in an FPC2 or FPC3, use a narrow-ended tool that fits inside the opening that leads to the button.
- Issue the following CLI command:
user@host>request chassis pic fpc-slot fpc-slot pic-slot pic-slot onlineFor more information about the command, see the Junos System Basics and Services Command Reference.
- To bring a MIC online:
- Press the MIC offline/online button until the MIC LED lights green.
- Issue the following CLI command:
user@host>request chassis mic fpc-slot mpc-slot pic-slot mic-slot onlineFor more information about the command, see the Junos System Basics and Services Command Reference.
The normal functioning indicator LED confirms that the component is online. You can also verify correct DPC or MPC functioning by issuing the show chassis fpc command or correct MIC or the PIC functioning by issuing the show chassis fpc pic-status command.
