Ensure that the power to the interconnect is turned off and that the power cables are disconnected. Label and disconnect all cables. 3. Remove all QM501, QM502, QM511C, and QM511L modules and set aside in a safe location using anti-static bags. 4. Remove all QM503 controller cards and set aside in a safe location using anti-static bags. 5. Remove all QM562 fan trays and all blank cards. 6. Disconnect the two QM573-x midplane wiring looms from the top of the midplane. If necessary, carefully remove one of the card guides to gain access. Position the cables out of the way. 7. Fit two midplane handles to the board. 8. Slacken off all the captive fasteners holding the midplane in place, being careful not to let the midplane slip out of position, thereby risking damage.
