Common Signs of a Faulty xw4600 Power Supply

A defective power supply can cause several symptoms:

• The workstation does not turn on

• System shuts down unexpectedly

• Workstation becomes unstable

• Intermittent power loss

• Internal hardware does not receive power correctly

Resetting the Power Supply

If an overload triggers the power supply overload protection, all power is immediately disconnected. To reset the power supply :

1. Disconnect the power cord from the workstation

2. Determine what caused the overload and fix the problem

3. Reconnect the power cord and reboot the workstation

These symptoms can also be caused by other components. We recommend diagnosing the workstation before purchasing a replacement PSU.
