PCIe switch board cable routing

Use this section to understand the cable routing for the PCIe switch board.

Note

• If necessary, attach the labels to both ends of the cables.
  1. Attach the white space portion of the label to one end of the cable.
  2. Wrap the label around the cable and attach it to the white space portion.
  3. Repeat to attach the other label to the opposite end of the cable.
  Figure 1. Label application
  
  
• Route the signal and sideband cables over the system board as illustrated below.
• Route the power cable under the compute tray as illustrated below.
• Route the cables through the cable holders and sponges as illustrated below.
