If the power supply is interrupted due to a power failure, the system returns to its last state when the power
supply is restored:

supply is restored.
•If the system was powered off at the time of the power failure, the system remains off when the power
supply is restored.
Boot Menu
Use the boot menu to restart or troubleshoot your ReadyNAS storage system.Your storage system has the
following boot modes:
•Normal. Initiates a normal boot process, just like booting using the Power button.
•Factory default. Initiates a short disk test that takes approximately 5 minutes. After the disk test, a
10-minute time-out period begins.
WARNING:
The factory default reboot process resets the storage system to factory
settings, erases all data, resets all defaults, and reformats the disk to X-RAID.
-If you want to cancel the factory default process, power off the storage system before the 10-minute
time-out ends.The system powers down safely without causing any data loss.
-If you want to reset the system to factory default settings, do not power off your system. After the
10-minute time-out period, the factory default process begins.
To start the factory default process immediately, press the Backup button during the
10-minute time-out period.

to defaults.
•Tech support. Boots into a low-level diagnostic mode. Use the tech support boot mode only when a
NETGEAR technical support representative instructs you to do so.
•Volume read only. Mounts a volume as read-only. Use this option when you are attempting to rescue
data off a disk during a disaster recovery.
