PSU interposer cable routing

Use the section to understand the cable routing for the PSU interposer.

Based on the location, select the corresponding routing plan:
Note
  • Connections between connectors; 1↔1, 2↔2, 3↔3, ... n↔n
  • When routing the cables, ensure that all cables are routed appropriately through the cable guides.
Attention
Strictly observe the following instructions to avoid damaging cable sockets on the system board. Any damage to the cable sockets might require replacing the system board.

  • Connect cable connectors vertically or horizontally in alignment with the orientations of the corresponding cable sockets, avoiding any tilt.

  • To disconnect cables from the system board, do as follows:

    1. Press and hold all latches, release tabs, or locks on cable connectors to release the cable connectors.

    2. Remove the cable connectors vertically or horizontally in alignment with the orientations of the corresponding cable sockets, avoiding any tilt.
      Note
      The cable connectors might look different from those in the illustration, but the removal procedure is the same.

Note
  • When routing through the cable guides on the CPU complex chassis, keep the integrated diagnostics panel cable and the GPU management cable on top of the power cables, and keep them parallel to each other. As illustrated in b.
  • Ensure not to place the power cables on the right and left ends of the manifold. As illustrated in a.
