Power Supply (Server 315, 325)



  Power Supply
NOTE: Verify that the voltage-select switch is set for the correct voltage. If the voltage switch is set to the wrong position, permanent damage might occur to the server when you power it on.

If the power-on indicator is not on, and the power-supply fan is not running, check the power cord for proper installation and continuity.

If the power cord is OK, either the power supply is defective or a defective device is causing the power supply to shut off. Check the power supply voltages.

The power supply is rated at 250 watts. Too many devices (adapters or hard disk drives) can cause power consumption to exceed 250 watts and cause the power supply to shut down. Remove adapters or devices to determine if this is the cause.

If the voltages are incorrect, replace the power supply. If the voltages are correct, and the Symptom-to-FRU index does not solve the problem, go to 'Undetermined Problems'
