Moving the PCIe risers and mezzanine card

As part of the controller replacement process, you must move the PCIe risers and mezzanine card from the impaired controller module to the replacement controller module.

1. Move PCIe risers one and two (when counting from left and going right) from the impaired controller module to the replacement controller module.
   1. Remove any SFP or QSFP modules that might be in the PCIe cards.
   2. Rotate the riser locking latch on the left side of the riser up and toward air duct.
      The riser raises up slightly from the controller module.
   3. Lift the riser up, and then move it to the replacement controller module.
   4. Loosen the thumbscrews on the mezzanine card, and gently lift the card back and out of the socket, and then move it to the replacement controller module.
   5. Repeat this step for riser number 2.
2. Remove riser card number 3 (far right), remove the mezzanine card, and install both into the replacement controller module:
   1. Remove any SFP or QSFP modules that might be in the PCIe and mezzanine cards.
   2. Rotate the riser locking latch on the left side of the riser up and toward air duct.
      The riser raises up slightly from the controller module.
   3. Lift the riser up, and then set it aside on a stable, flat surface.
   4. Loosen the thumbscrews on the mezzanine card, and gently lift the card directly out of the socket, and then move it to the replacement controller module.
   5. Install the mezzanine in the replacement controller and secure it with the thumbscrews.
   6. Install the third riser in the replacement controller module directly over the mezzanine card.
