Internal cable routing

Use this information to route the cables for one-processor and two-processor configurations.

Attention
Make sure the OSFP module is installed and all cables are connected to the network board.
Note

Disengage all latches, release tabs, or locks on cable connectors when you disconnect cables from the system board. Failing to release them before removing the cables will damage the cable sockets on the system board, which are fragile. Any damage to the cable sockets might require replacing the system board.

There are two cable ties on the GPU node. Unfasten the cable tie before removing the cables from the tray. After connecting the cables to the tray, bundle the cable tie to secure the cables.

SD650-N V3 cable routing​

Follow the information below for SD650-N V3 cable routing.

  1. Connect the carrier board power and side band cable.

    Figure 3. Carrier board power and side band cable routing

    FromTo
    1 Power and side band connector (on carrier board)1 Power connector (on GPU node power distribution board)
  2. Connect the MCIO cables from the GPU node to the Compute node.
    Attention
    Make sure to follow the cable installation sequence: 1 → 2 → 3 → 4

    1 MCIO 11 PCIe x 16 MCIO 3 connector
    2 MCIO 22 PCIe x 16 MCIO 4 connector
    3 MCIO 33 PCIe x 16 MCIO 1 connector
    4 MCIO 44 PCIe x 16 MCIO 2 connector
    5 Stud (in between the nodes) Make sure the cables are routed around the stud as shown in the illustration.

  3. Bundle the cable ties (1) to secure the MCIO 1 cable and the carrier board power and side band cable.
