Replacing an FPIC of the LPU

Replacing an FPIC of the LPU

This section describes the precautions and procedures for replacing an FPIC.

Context

Flexible Plug-in Card (FPIC) Line Processing Unit (LPU) boards include the LPUF-240, LPUF-120, and LPUF-101.

Before replacing an FPIC, note the following:

  • You must prepare the same kind of FPIC as the one that is to be replaced.

  • FPICs do not support hot swap. Before replacement, you must power off the LPU where the FPIC to be replaced resides.

Tool

Before replacing an FPIC, you need the following tools:

  • ESD wrist strap or ESD gloves

  • Phillips screwdriver

  • ESD bag

Procedure

  1. Check the location of the FPIC to be replaced.

    Before pulling out an FPIC to be replaced, first check the location of the FPIC, that is, the cabinet, chassis, and slot where the FPIC resides. Then, locate the FPIC to be replaced in the chassis and label the FPIC.

  2. Check whether there is any bent pin in the connector of the new FPIC.
  3. Pull out the cables from the FPIC and label the cables with the corresponding interface numbers.
  4. Power off the LPU to be replaced.

    Use either of the following methods:

    • Press and hold the OFL button on the panel of the LPU for five seconds until the OFL indicator turns on.

    • In the user view, run the power off slot slot-id command.

  5. Pull out the FPIC to be replaced from the LPU.
    1. Put on the ESD wrist strap and connect the ground terminal to the ESD jack on the rack.
    2. Using the Phillips screwdriver, turn the two captive screws counter-clockwise to loosen them, as shown in Figure 3-9 (1).
    3. Hold the captive screws of the FPIC and pull out the FPIC, as shown in Figure 3-9 (2).

      • Pull out the LPU slowly and smoothly to prevent it from hitting neighboring boards and affecting running boards.
      • Touching parts on the LPU when swapping it may damage the LPU.
      Figure 3-9  Removing an FPIC from the LPU

    4. Place the removed FPIC into the ESD bag.
  6. Insert a new FPIC into the LPU.
    1. Take out the new FPIC from the ESD bag.

      • Pull out the LPU slowly and smoothly to prevent it from hitting neighboring boards and affecting running boards.
      • Touching parts on the LPU when swapping it may damage the LPU.

    2. Hold the captive screws of the FPIC, and insert the FPIC smoothly along the guide rails of the slot until the FPIC is completely seated in the slot, as shown in Figure 3-10 (1).
    3. Using the Phillips screwdriver, turn the two captive screws clockwise to tighten them, as shown in Figure 3-10 (2).

  7. Connect the cables to the corresponding interfaces in the original sequence.
  8. Log in to the device and run the power on slotslot-id command to power on the LPU backplane whose FPIC has been replaced.
  9. Check the running status of the new FPIC.

    Check the running status of the new FPIC in the following ways:
    • Check the STATUS indicator on the panel of the FPIC. If it is on (green), the FPIC is working normally.
    • Check the alarms. If the system does not generate any alarm related to the new FPIC, the new FPIC is working normally.
    • Run the display device command on the console interface. If the LPUs in the corresponding slots are working normally, the following is displayed:
      <sysname> display device
      NIP6830's Device status:

    • Run the display device pic-status command on the console interface to view the running status of FPICs. If the FPICs on the corresponding LPUs are working normally, the following is displayed:
