Internal cable routing

This section provides information on internal cable routing of specific components.

When ThinkEdge SE100 is in Rack mount configuration, the 1U2N enclosure can contain up to two ThinkEdge SE100 nodes with PCIe expansion kit while 1U3N can contain up to three ThinkEdge SE100 nodes. Make sure to follow the steps below to connect the cables to the rear I/O connectors of the ThinkEdge SE100 Node and expansion kits and ensure that the relevant cables pass through the cable clips and guides.

Procedure
  1. Remove the following components that are installed on the enclosure and put them in a safe, static protective place.

  2. Remove the crossbar from the enclosure. See the step 2 in Remove a power adapter (Rack mount).

  3. Loosen the two screws that secure the rear bracket; then, remove the rear bracket from the enclosure.

  4. Ensure that the relevant cables pass through the cable clips and guides as illustrated below:

Attention
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. 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.
