Troubleshooting Scenarios and Solutions
This section presents an extensive overview of various troubleshooting scenarios and includes possible
solutions for each. Before replacing the power supply, use the Built-In Self-Test (BIST) feature to learn if
the power supply still works.
To test the power supply:
1 Disconnect all internal power supply cables.
2 On the rear panel of the workstation, look through the ventilation holes above the power cord
connector for a green LED light. If the light is visible, the power supply is functional.
