Removing a Cable on an MX960 DPC, MPC, MIC, or PIC

Removing and installing cables on a DPC, MPC, MIC, or PIC does not affect router function, except that the component does not receive or transmit data while its cable is disconnected.

To remove a fiber-optic cable:

1. If the component connects to fiber-optic cable, have ready a rubber safety cap for each cable and transceiver.
2. If removing all cables connected to the component, use one of the following methods to take the component offline:
   • To take a DPC or an MPC offline:
     • Press and hold the corresponding online button on the craft interface. The green OK LED next to the button begins to blink. Hold the button down until the LED goes off.
     • Issue the following CLI command:
       
       

       user@host>request chassis fpc slot slot-number offline

       For more information about the command, see the Junos System Basics and Services Command Reference.

   • To take a PIC offline:
     • Press the online/offline button on the PIC. For a PIC installed in an FPC3, use a narrow-ended tool that fits inside the opening that leads to the button. Press and hold the button until the PIC LED goes out (about 5 seconds).
     • Issue the following CLI command:
       
       

       user@host> request chassis pic fpc-slot fpc-slot pic-slot pic-slot offline

       For more information about the command, see the Junos System Basics and Services Command Reference.

   • To take a MIC offline:
     • Press the online/offline button on the MIC. Use a narrow-ended tool that fits inside the opening that leads to the button. Press and hold the button until the MIC LED goes off (about 5 seconds).
     • Issue the following CLI command:
       
       

       user@host> request chassis mic fpc-slot mpc-slot pic-slot mic-slot offline

       For more information about the command, see the Junos System Basics and Services Command Reference.

3. Unplug the cable from the cable connector port. If the PIC uses fiber-optic cable, immediately cover each transceiver and the end of each cable with a rubber safety cap.

   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.

4. Remove the cable from the cable manager and detach it from the destination port.
