Replacing SRX5800 Services Gateway IOCs

To replace an IOC, perform the following procedures:

  1. Removing an SRX5800 Services Gateway IOC
  2. Installing an SRX5800 Services Gateway IOC

Removing an SRX5800 Services Gateway IOC

An IOC weighs up to 13.1 lb (5.9 kg). Be prepared to accept its full weight.

To remove an IOC (see Figure 74):

  1. Have ready a replacement IOC or IOC blank panel and an antistatic mat for the IOC. Also have ready rubber safety caps for each optical interface on the IOC you are removing.
  2. Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  3. Label the cables connected to each port on the IOC so that you can later reconnect the cables to the correct ports.
  4. Use one of the following methods to take the IOC offline:
    • Press and hold the corresponding IOC 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 PDF Document.

  5. Disconnect the cables from the IOC.

    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.

    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.

  6. Immediately cover each optical transceivers and the end of each fiber-optic cable with a rubber safety cap.
  7. Arrange the disconnected cables in the cable manager to prevent the cables from developing stress points.
  8. Simultaneously turn both of the ejector handles counterclockwise to unseat the IOC.
  9. Grasp the handles and slide the IOC straight out of the card cage halfway.
  10. Place one hand around the front of the IOC and the other hand under it to support it. Slide the IOC completely out of the chassis, and place it on the antistatic mat or in the electrostatic bag.

    Caution: The weight of the IOC is concentrated in the back end. Be prepared to accept the full weight—up to 13.1 lb (5.9 kg)—as you slide the IOC out of the chassis.

    When the IOC is out of the chassis, do not hold it by the ejector handles, bus bars, or edge connectors. They cannot support its weight.

    Do not stack IOC on top of one another after removal. Place each one individually in an electrostatic bag or on its own antistatic mat on a flat, stable surface.

  11. If you are not reinstalling an IOC into the empy slot within a short time, install a blank IOC panel over the slot to maintain proper airflow in the card cage.

    Caution: After removing an IOC from the chassis, wait at least 30 seconds before reinserting it, removing an IOC from a different slot, or inserting an IOC into a different slot.

Installing an SRX5800 Services Gateway IOC

An IOC weighs up to 14.5 lb (6.6 kg). Be prepared to accept its full weight.

To install an IOC (see Figure 75):

  1. Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  2. Place the IOC on an antistatic mat or remove it from its electrostatic bag.
  3. Identify the slot on the services gateway where it will be installed.
  4. Verify that each fiber-optic transceiver is covered with a rubber safety cap. If it does not, cover the transceiver with a safety cap.
  5. Orient the IOC so that the faceplate faces you.
  6. Lift the IOC into place and carefully align the top and bottom edges of the IOC with the guides inside the card cage.
  7. Slide the IOC all the way into the card cage until you feel resistance.
  8. Grasp both ejector handles and rotate them clockwise simultaneously until the IOC is fully seated.
  9. Remove the rubber safety cap from each fiber-optic transceiver and cable.

    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.

  10. Insert the cables into the cable connector ports on each IOC (see Figure 76).
  11. Arrange the cable in the 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: 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.

  12. Use one of the following methods to bring the 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 PDF Document.

    Caution: After the OK LED turns green, wait at least 30 seconds before removing the IOC again, removing an IOCfrom a different slot, or inserting an IOC in a different slot.

You can also verify that the IOC is functioning correctly by issuing the show chassis fpc and show chassis fpc pic-status commands.
