Solving power supply problems

This section presents power supply troubleshooting scenarios.

Testing power supply

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:

Unplug the AC power.

Remove the power supply.

Plug in AC power and verify the following:

●

If the green BIST LED on the rear of the workstation is illuminated

and

the fan is spinning, the

power supply is functional.

●

If the green BIST LED is not illuminated

the fan is not spinning, replace the power supply.

See the

Rear panel components

section of this service guide to locate the BIST LED on this workstation.

Power supply problems

Problem

Cause

Solution

Power supply shuts down

intermittently.

Power supply fault.

Replace the power supply.

Workstation powers off and the

Power LED flashes red 2 times

(once every second), followed by a

2-second pause.

Processor thermal protection

is activated.

A fan might be blocked or not

turning.

The processor heatsink fan

assembly is not properly

attached to the processor.

Ensure that the workstation air vents are not blocked.

Open the access panel and press the workstation

power button.

Verify that the system fan is running.

Verify that the processor heatsink fan spins.

If the heatsink fan is not spinning, verify that the fan

cable is plugged into the system board connector.

Verify that the fan is properly seated.

Replace the processor heatsink.

Power LED flashes red (once every

2 seconds).

Power failure (power supply is

overloaded).

Determine whether a device is causing the problem

by performing the following:

Disconnect AC power.

Remove all attached devices.

Power on the workstation.

If the system enters the POST, perform the following:

Power off the workstation.

Replace one device at a time and repeat this

procedure until a failure occurs.

Replace the device causing the failure

Continue adding devices one at a time to verify

that all devices are functioning.

Verify power supply functionality.
