To remove and install system cables:

1. Turn off the power button on the back panel and all of the peripherals connected to the workstation.
2. Remove the left-side access panel.
3. Gently lay the system on its right side on a stable, nonslip surface.
4. Replace any cables that need to be replaced
5. Ensure that all cable routing is correct, and that all of the cable connectors are properly seated, before reinstalling the left-side access panel. see FIGURE 4-34 Cabling Diagram in the User guide
