Replacing an SRX5800 IOC or Port Module Cable

To replace an IOC or port module cable, perform the following procedures:

  1. Removing an SRX5800 IOC or Port Module Cable
  2. Installing an SRX5800 IOC or Port Module Cable

Removing an SRX5800 IOC or Port Module Cable

Removing and installing IOC or port module cables does not affect services gateway function, except that the component does not receive or transmit data while its cable is disconnected.

To remove a fiber-optic cable from an IOC or a port module:

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

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

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

    • To offline an IOC:
      • 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 OS System Basics and Services Command Reference.

  3. Unplug the cable from the cable connector port. If the port module 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.

Installing an SRX5800 IOC or Port Module Cable

To install a cable in an IOC or a port module::

  1. Have ready a length of the type of cable used by the component.
  2. 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.

  3. Insert the cable connector into the cable connector port on the component faceplate.
  4. Arrange the cable in the standard or extended cable manager 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: 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.

    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.

  5. Insert the other end of the cable into the destination port.
  6. Repeat the previous steps for any additional cables.
  7. If the component is offline (its failure indicator LED is lit), use one of the following methods to bring it online.
    • To bring an IOC online:
      • Press and hold the corresponding IOC 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 online

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

    • To bring a port module online:
      • Press the port module online button until the PIC LED lights green. 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 online

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

    The normal functioning indicator LED confirms that the component is online. You can also verify correct IOC functioning by issuing the show chassis fpc command or correct PIC functioning by issuing the show chassis fpc pic-status command.
