Installing an IOC

To install an IOC (see Figure 7):

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis. For more information about ESD, see Preventing Electrostatic Discharge Damage.
  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 sides 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. If the IOC uses fiber-optic cable, remove the rubber safety cap from each 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 appropriate cables into the cable connector ports on each IOC (see Figure 8). 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.

    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.

  11. Use one of the following methods to bring the IOC online:

    Caution: After the OK LED turns green, wait at least 30 seconds before removing the IOC again, removing an IOC from 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, as described in the JUNOS System Basics and Services Command Reference.
