Leakage sensor module cable routing

Use this section to understand the cable routing of the leakage sensor module.

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.






Based on the location of the leakage sensor module, 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.

Note
For better cable arrangement, it is required to install the hoses and leakage sensor module to a designated holder, and make sure that the module is secured in holder clips. Use the illustration below or Install the Lenovo Neptune® Processor Direct Water Cooling Module for details.
