Install the riser assembly to the node

Procedure

1. If bottom M.2 cabled adapter is installed, make sure the cables of bottom M.2 cabled adapter are connected to the system board properly. See Cable routing for bottom M.2 cabled adapter.
2. Connect the riser assembly cables.
   Note

   If necessary, remove the memory modules from DIMM slot 3 and 4 for easier operation. See Remove a memory module.

   Cable	From: PCIe cabled riser card	To: System board	Cable length
   1	Power connector	M.2 cabled adapter / PCIe cabled riser card power connector	100mm
   2	2a MCIO 1 connector 2b MCIO 2 connector	2a MCIO 1 connector 2b MCIO 2 connector	140/120mm

   Note

   Make sure to route the cables as shown in the illustration.
   1. Connect 1 the power cable to the system board.
   2. Connect 2a the MCIO2 branch of riser card signal cable to the system board.
   3. Connect 2b the MCIO1 branch of riser card signal cable to the system board.
3. Reinstall the processor air baffle. See Install the processor air baffle and air flow sensor board.
   Note

   Make sure to adjust the processor air baffle according to the configuration.

5. Secure the riser assembly to the node.
   1. Tighten the three captive screws on the top of the riser assembly.
   2. Tighten the three screws on both sides of the node.
   3. Tighten the two thumbscrews in the front of the riser assembly.

6. Bundle the riser assembly cables together with a velcro strap; then, push the bundled cables toward the riser card.
   Note

   To make sure adequate system cooling, the cables should be routed away from the space for PMB air baffle.
