Replace the Fabric Interconnect F1-15 QDR Fabric Board

The Fabric Interconnect F1-15 Fabric Board is on the rear of the chassis. To replace the Fabric Interconnect F1-4 Fabric Board, you will need a #2 Phillips-head screwdriver.

To replace the Fabric Interconnect F1-15 QDR Fabric Board, follow this procedure:

1. Power down the Fabric Interconnect.
2. Disconnect all cables attached to the server ports, as well as any other cables that could interfere with the Fabric Board's removal.
3. Using a screwdriver, loosen the captive screws in the release levers by turning them counterclockwise (1). See Unlocking the Fabric Interconnect F1-15 QDR Fabric Board.

4. Grasp both of the Fabric Board's release levers, and simultaneously swing them outward (2).
5. Grasping both of the release levers, slide the Fabric Board out of the chassis. See Removing the Fabric Interconnect F1-15 QDR Fabric Board.

6. Remove the QDR Fabric Board from the packaging, and orient the module so that it is right side up.
7. Orient the QDR Fabric Board so that the sheet metal surface is on the bottom, and pivot the QDR Fabric Board's handles so that they are pointing directly towards you—not flush with the module.

   At the far end of each of the Fabric Board's handles, notice there is a notch. This notch will meet a part in the chassis, and allow you to lock the Fabric Board into the system midplane and power channel.

8. Supporting the QDR Fabric Board under the sheet metal bottom, hold the Fabric Board level and align it with the empty Fabric Board bay in the Fabric Interconnect. Inserting the QDR Fabric Board into a Fabric Interconnect F1-15 shows aligning and inserting the QDR Fabric Board.

   Caution  -  Pay attention to the leading edges of the Fabric Board—the edges that will contact and insert into the chassis first. These edges must be kept horizontal. If you tip one side of the Fabric Board, it possible to insert the Fabric Board incorrectly. Make sure you hold the Fabric Board level while you insert it.

9. When the Fabric Board is properly aligned, gently slide it in until you feel some resistance, then check the notches at the end of the Fabric Board's handles to make sure they are contacting the guides on the inside of the chassis.

   ---

   Caution  -  Do not force the Fabric Board into place. If it does not slide in easily, remove it and attempt to insert it again. Make sure that the leading edges are level, and you are keeping the Fabric Board level while you slide it in.

   ---

10. When the notches and guides are properly positioned, press the Fabric Board's handles inward to seat the Fabric Board (1) as shown in Seating the QDR Fabric Board into a Fabric Interconnect F1-15. The Fabric Board is properly seated when it and its handles lie flush against the chassis.

    ---

    Caution  -  Do not force the levers. They should glide easily when properly aligned. If you feel uneven resistance or the release levers do not move easily, gently swing the levers away from each other, partially remove the Fabric Board, and attempt Step 8 through Step 10 while paying attention to how the release levers contact the edge of the chassis.

11. When the release levers have correctly locked the QDR Fabric Board into the chassis, use the screwdriver to secure the captive screws in the release levers (2).

    ---

    Caution  -  When tightening screws, make sure to tighten them to lightly snug. Do not overtighten screws or they can break.

    ---

12. Reconnect the Fabric Interconnect to facility power, then power on the Fabric Interconnect, and allow it to completely boot up.

    The Fabric Board will boot, and when the board completes is bootup and passes to runtime, the Power LED will glow. The Power LED does not glow until the Fabric Board is in runtime.
