Caution: Do not operate the product until the ambient temperature is within the specified operating range. If the drives have been recently installed make sure they have had time to acclimatize before operating them.
The status and drive activity LEDs will turn blue when the product's power button is pressed and the disks should spin.
The LEDs will turn off once the system has shut down.
Note: When the product is operating, a short push of the on/off button will turn the 4-bay NAS off or, place the 4-bay NAS into deep sleep mode if the option has been configured in NAS OS. A long push of more than four seconds will cut the power from the NAS, forcing it to shut down immediately. A long push is not recommended as it may result in data loss.
