Netgear EDA500 – ReadyNAS Expansion Chassis 5-Bay, Diskless 하드웨어 매뉴얼

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.

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.

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.

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.

Memory test. Performs a memory test. The pass or fail result is reported on the status display screen.

Test disk. Performs an offline full disk test. This process can take four hours or more, depending on
the size of your disks. Any problems are reported in the system logs. For more information about viewing
the system logs, see the ReadyNAS OS 6 Software Manual, which is available at
