Step 5: Remove the PCIe risers
As part of the controller replacement process, you must remove the PCIe modules from
the impaired controller module. You must install them into the same location in the
replacement controller module once the NVDIMMS and DIMMs have moved to the
replacement controller module.
1. Remove the PCIe riser from the controller module:
a. Remove any SFP or QSFP modules that might be in the PCIe cards.
b. Rotate the riser locking latch on the left side of the riser up and toward the fan modules.
The riser raises up slightly from the controller module.
c. Lift the riser up, shift it toward the fans so that the sheet metal lip on the riser clears the edge of the
controller module, lift the riser out of the controller module, and then place it on a stable, flat surface.

2. Repeat the preceding step for the remaining risers in the impaired controller module.
3. Repeat the above steps with the empty risers in the replacement controller and put them away.
Step 6: Move system DIMMs
To move the DIMMs, locate and move them from the impaired controller into the
replacement controller and follow the specific sequence of steps.
