Installing an I/O Card with Fiber-Optic Media Interfaces

To install an IOC that supports fiber-optic media interfaces:

  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. If you have not already done so, power off the device by pressing the Power button on the front panel of the Switch Fabric Board (SFB) for three to five seconds.

    The PWR LED blinks to show you that the device is shutting down. Wait for the device to shut down before proceeding.

  3. Place the IOC on an antistatic mat or remove it from its electrostatic bag.
  4. Identify the slot on the services gateway where it will be installed. You can only install IOCs in front-panel slots.
  5. Orient the IOC so that the faceplate faces you. Slide the IOC all the way into the card cage until you feel resistance.
  6. Tighten the screws on either side of the card.
  7. If you are installing additional IOCs at this time, repeat steps Step 3 through Step 6, then continue with the following steps to connect the appropriate cables.
  8. Install XFP or SFP transceivers as appropriate into the sockets on the IOC:
    1. Take each new transceiver to be installed out of its electrostatic bag and identify the port on the IOC where it will be installed.
    2. Verify that each transceiver is covered with a rubber safety cap. Cover any transceivers without a safety cap.
    3. Remove the rubber dust covers from each SFP or XFP socket in which you will install a transciever.
    4. Carefully align the transceiver with the sockets in the IOC. The connectors should face the IOC.
    5. Slide the transceiver until the connector is seated in the IOC slot. If you are unable to fully insert the transceiver, make sure the connector is facing the right way.
    6. Close the ejector handle of the transceiver.
  9. 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. Secure the cables so that they are not supporting their own weight. Place excess cable out of the way in a neatly coiled loop. 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.

Warning: Never lift the services gateway using the handles on the front panels of the IOCs or other CFM cards. The handles might come off, causing the chassis to drop and inflicting possible grave injury.
