Remove and Install the Power Feedback Circuit Board and Bracket - Frame 6L

Replace a power feedback circuit board and bracket with kit catalog number SK-RM-PFB2-F5-F6-F6L. Follow these steps to remove and install the power feedback circuit board and bracket.
  1. Review the product advisories in Before You Begin.
  2. Remove power from the system.
  3. Remove the cover from the chassis. See Remove and Install the Frame 6L Cover.
  4. If used, disconnect the drive peripheral interface (
    DPI™
    ) cable from the connector (port 2) on the human interface module (HIM) cradle (XT) or the mini-DIN connector (port 2) on the control pod (standard).
    TIP: If a cable is not connected to the
    DPI™
     port on the HIM cradle (XT), be sure to leave the protective cover installed.
  5. Disconnect any Ethernet cables from the Ethernet ports on the bottom of the main control board.
  6. If used, disconnect the plug-in terminal block TB1 on the bottom of the main control board.
  7. If used, disconnect any I/O wiring terminal blocks from an installed option module.

    TIP: The inner control pod chassis is shown removed from the outer control pod chassis for clarity only.
  8. Remove the two M4 x 10 mm slotted Torx screws that secure the HMI flex circuit connector (A) to the power interface circuit board.
  9. IMPORTANT: The control pod contains a connector that connects to an edge connector on the power feedback circuit board beneath it. Take care when lifting the control pod off the chassis so circuit board damage does not occur.
  10. Remove the four M4 x 10 mm slotted Torx screws that secure the control pod to the chassis and remove the control pod.

  11. TIP: The side of the chassis is not shown for clarity only.
  12. Remove the four M4 x 10 mm Torx screws that secure the power feedback circuit board and support bracket to the chassis and carefully lift the bracket and board edge connectors off the connectors on the power circuit board.

  13. IMPORTANT: Circuit boards that are contained in renewal kits with XT contain dielectric grease on the edge connectors, where present. Do not touch or remove the grease from circuit board edge connectors. A non-greased connector can lead to corrosion. If before you install the new board, grease is removed from an edge connector or is contaminated, do not install the circuit board. You must clean and reapply grease to the affected edge connector or connectors. See Clean and Apply Dielectric Grease to a Fiber Transceiver Edge Connector (XT).
  14. On the new power feedback board, for each protective cover on the bottom edge connectors, hold the tab (B) on the cover and carefully remove the cover from the circuit board. Do not touch the edge connectors.

  15. Complete the remaining steps to install the power feedback board and bracket in the reverse order of removal.
    • Before reinstallation of the control pod and support bracket, remove the protective cover (C) from the upper edge connector on the power feedback circuit board.
    • Verify that the HMI flex-circuit connector on the lower, right side of the control pod seats properly on the edge connector on the top of the power feedback board when you re-install the control pod.
