Q: Can you confirm that the NAS is receiving power?
A: Make sure the power cord is properly connected, and then push the power button until the Status LED turns ON.
Q: Have you connected a USB storage device?
A: The NAS may be attempting to boot from it. Unplug the device and retry to reboot the system.
Q: Does the motherboard battery need to be replaced?
A: A non-functioning motherboard battery could prevent the system from booting. The best way to verify that this is the problem is to connect a monitor, mouse, and keyboard to the NAS and reboot. If the display reads "CMOS Checksum Error", the motherboard battery is probably the cause of the problem. Contact Seagate technical support for confirmation and help.
Q: Is there a problem with the power supply?
A: Connect a monitor, mouse, and keyboard, and turn your product on. If you do not see anything on the monitor, the problem may result from the NAS's power supply units. Your NAS has a single power supply and does not allow for redundancy. Contact Seagate technical support if you believe that the power supply has failed.
Q: Have you connected more than three bus-powered USB devices or is one of your devices drawing an inordinate amount of power?
A: Connect no more than three bus-powered USB devices and/or make sure that none of the devices is drawing an inordinate amount of power.
Q: Did the product turn off as soon as the USB device and the 4-bay NAS's USB port came into contact?
A: The USB device may have caused a short circuit. Unplug any USB devices you have connected since the failure and reboot the product.
Q: Have you tried to restart the system?
A: Shut down the NAS using the operating system or, if you cannot access Windows, push the front button. If nothing happens after a few minutes, force the NAS to turn off by pressing and holding the front button for more than four seconds. Once off, restart the product by pushing and immediately releasing the front button. Note that this is not recommended in most situations as it may result in data loss.
Q: Is the ambient temperature too high? Is the air output blocked?
A: If the ambient temperature is below 95°F/35°C and the fan output is cleared, you may have a malfunctioning fan. Contact Seagate technical support for confirmation.
Q: Where can I check the firmware version?
A: Navigate to the Seagate System Monitor Support page and review Firmware.
