HP D3604-90004 If the LED Readout Shows a Fan Fault FF, If the LED Readout Shows a Line Fault LF

4 Troubleshooting

If the LED Readout Shows a Fan Fault (FF)

If the system powers on, but the main chassis fan is not operating and/or “FF” is displayed, open the door and verify the fan cable is connected to the fan connector on the management board. (Refer to the cable management label on the inside of the door.)

CAUTION Do not operate the storage system when the fan is not operating.

If the LED Readout Shows a Line Fault (LF)

If the line power is not connected properly to one of the power supplies and “LF” blinks alternately with HP, verify the line power is connected properly to each power supply device and to a power source. If the error message persists, power down the storage supply and replace the line power.

If the LED Readout Shows a Power Supply Fault (PF)

If the voltage switch is not set properly or power supply is not working properly and “PF” blinks alternately with HP, power down the storage supply and verify the line power voltage matches the voltage switch setting (for example, 115 volts in the U.S. and 230 volts in Europe). If the error message persists, power down the storage supply and replace the power supply.

If the SCSI Devices Fail to Spin Up

If the storage system powers up, but the SCSI devices fail to spin up (usually indicated by the failure of the LEDs on the devices to light), do the following:

∙Remove and reinstall all hot-swap drive modules.

∙Verify the power distribution cable is plugged into:

àConnector PD1 on the management board.

àAny devices in the SCSI device shelves.

àThe upper and lower hot-swap cages.

∙Verify the switches on the back of the hot-swap cages are set correctly. (Refer to manufactured configuration label to see default settings.)
