Replace Flexible PIC Concentrators on the PTX12008

Maintaining the PTX12008 includes removing and installing the Flexible PIC Concentrators.

Flexible PIC Concentrators (FPCs) in the PTX12008 are hot-removable and hot-insertable field-replaceable units (FRUs). You can remove and replace the FPCs without powering off the PTX12008 or disrupting the router functions.

Remove an FPC from the PTX12008

Before you remove an FPC:

  • Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage. See Prevention of Electrostatic Discharge Damage.

  • If there are any optical cables or transceivers installed in the FPC, remove them. See Remove an OSFP or QSFP-DD Transceiver.

  • Ensure that you have the following parts and tools:

    • An ESD grounding strap—not provided

    • An antistatic bag or an antistatic mat—not provided

    • Two ejector tool handles —provided

    • A replacement FPC—not provided

    • A blank cover panel (in case you're not replacing the FPC)—provided

    • A second person to assist with handling the FPC, or a lift—not provided

To remove an FPC:

  1. Place the antistatic bag or antistatic mat on a flat, stable surface.
  2. Wrap and fasten one end of the ESD grounding strap around your bare wrist and connect the other end of the strap to the ESD point on the front panel of the chassis.

  3. If the front door is closed, open it.

    • Loosen the two captive screws on the door by using your fingers or a Phillips (+) screwdriver, number 2.

    • Press the release buttons on the sides of the door and gently pull the door away from the chassis.

  4. Label the cables connected to each port on the FPC so you can reconnect the cables to the correct ports.
  5. Take the FPC offline by using the request chassis fpc slot slot-number offline command.
  6. Insert the ejector tool handles into the receptacles on either sides of the faceplate of the FPC and press the button at the front of the tool to attach it to the FPC.
  7. Rotate the ejector tool handles counterclockwise until the card is fully unseated.
    CAUTION:
    The FPC weighs about 47 lb (21.3 kg). Have a second person to assist you to remove the FPC. If a second person is not available, use a lift to support the weight of the FPC.
  8. Hold the ejector tool handles and slide the FPC halfway out of the chassis.
    CAUTION:

    Do not stack FPCs on top of one another or on top of any other component. Place each FPC separately in the antistatic bag or on the antistatic mat placed on a flat, stable surface.
    CAUTION:

    Do not lift the FPC by holding the edge connectors or the faceplate. The edge connectors or the faceplate cannot support the weight of the FPC. Lifting the FPC by the edge connectors or faceplate might bend them, which would prevent the FPCs from being properly seated in the chassis.
  9. Grasp both sides of FPC at midpoint and remove the FPC from the chassis. Take care not to touch the connectors.
  10. Place the FPC in the antistatic bag or on the antistatic mat.
  11. If you are not installing an FPC in the FPC slot soon, install an FPC slot cover over the slot. This step protects the interior of the chassis from dust or other foreign substances and ensures that the airflow inside the chassis is not disrupted.

Install an FPC on the PTX12008

Before you install an FPC:

  • Ensure that you have taken the necessary precautions to prevent ESD damage. See Prevention of Electrostatic Discharge Damage.

  • Ensure that the router has sufficient power to power the FPC while maintaining its n+1 power redundancy. To determine whether the router has enough power available for the FPC, use the Power Calculator.

  • Ensure that you have the following parts and tools available:

    • An ESD grounding strap—not provided

    • A Phillips (+) screwdriver, number 2—not provided

    • Two ejector tool handles—provided

    • A second person to assist with handling the FPC, or a lift—not provided

To install an FPC:

  1. Wrap and fasten one end of the ESD grounding strap around your bare wrist and connect the other end of the strap to the ESD point on the front panel of the chassis.

  2. If the front door is closed, open it.

    • Loosen the two captive screws on the door by using your fingers or a Phillips (+) screwdriver, number 2.

    • Press the release buttons on the sides of the door and gently pull the door away from the chassis.

  3. If the FPC slot is covered, turn the screws on the cover counterclockwise and pull the slot cover gently out of the chassis. If there is an FPC installed in the slot, remove it (see Remove an FPC from the PTX12008).
  4. CAUTION:
    The FPC weighs about 47 lb (21.3 kg). Have a second person to assist you to remove the FPC. If a second person is not available, use a lift to support the weight of the FPC.
     Grasp both sides of FPC at midpoint and remove the FPC from the bag. Take care not to touch the connectors.
  5. Inspect the connector edge of the FPC and ensure that there is no physical damage. Installing a damaged FPC might damage the router.
  6. Insert the ejector tool handles into the receptacles on either sides of the faceplate of the FPC and press the button at the front of the tool to attach it to the FPC.
  7. Grasp both sides of the FPC at midpoint and lift it. With the help of a second person or a lift, move the FPC close to the chassis and align it with the FPC slots on the chassis.
  8. Slide the FPC all the way into the slot. Rotate the ejector tool handles clockwise until the FPC is fully seated.
  9. Bring the FPC online by using the request-chassis-fpc slot slot-number online command.
