Power State
If the power supply is interrupted due to a power failure, the system returns to its last state 
when the power supply is restored: 
• If the system was powered on at the time of the power failure, the system powers on 
when the power 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. 
Tip: To start the factory default process immediately, press the Backup 
button during the 10-minute time-out period.
• OS reinstall. Reinstalls the firmware from the internal flash to the disks. Use the OS 
reinstall boot mode when the system crashes and corrupts some configuration files. OS 
reinstall boot mode also resets some settings on your storage system, such as Internet 
protocol settings and the administrator password, 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.
