Install the PCIe riser assembly

Procedure

1. Make sure the signal cables of PCIe riser 1 are routed properly.
   1. Route the blue signal cable along the intrusion switch as shown.
   2. Route the silver signal cable through the cable wall. Press the cable down toward the system board to avoid interfering the retaining clips of memory module slots.
   Figure 1. PCIe riser 1 cable routing
   
   
2. Connect all the required cables to the PCIe adapters.
   Note

   Depending on the configuration, connect the following cables to the PCIe adapters if necessary:

   • GPU power cable to double-wide GPU adapter

   • RAID flash power module extension cable to ThinkSystem RAID 940-8i 4GB Flash PCIe Gen4 12Gb Adapter

   • Backplane signal cable to RAID adapter/HBA

     • Front BP + internal BP to x350 RAID adapter:

       • C0 connector to front BP

       • C1 connector to internal BP

     • For other configurations with drive backplane connecting to RAID adapter, connect the backplane signal cable to C0 connector of RAID adapter.

   • M.2 signal cable to C0 connector of RAID adapter/HBA

3. If the serial port module is installed, connect the serial port cable to the system board. See System-board connectors for cable routing to locate Serial port connector (COM).
4. Install PCIe riser 1.
   1. Align the riser assembly with the guide slots on the chassis; then, lower the riser assembly until it is firmly seated.
      Note

      When lowering the riser assembly down, make sure to route the PCIe adapter cables away from the heat sink.
   2. Fasten the two captive screws to secure the riser assembly.

5. Manage the signal cables.
   1. Manage the blue signal cable into the space between the processor air baffle and the chassis.
      Note

      Make sure that the blue signal cable does not cover the guide slot for the top cover.
   2. Manage the silver signal cable into the space between PCIe riser 1 and the chassis.

6. If applicable, manage all the GPU power cables into the cable guide of the processor air baffle.

Procedure

1. If the riser blank filler is installed, remove the riser blank filler.

2. Make sure the signal cables of PCIe riser 2 are routed properly.
   1. If applicable, secure the blue signal cable in cable clip A.
   2. Route the silver signal cable through the cable wall; then, secure the cable in cable clip C. Press the cable down toward the system board to avoid interfering the retaining clips of memory module slots.

7. If applicable, press the following cables down and make sure that the cables are under the cable clip of the processor air baffle.

   • Signal cable of internal drive backplane

   • Power cable of internal drive backplane

   • The blue signal cable of PCIe riser 2
