1. Getting Started
Congratulations on your purchase of a NETGEAR ReadyNAS® storage system. This manual

NETGEAR ReadyNAS OS 6 Rack-Mount Storage Systems
Additional Documentation
For detailed information about configuring, managing, and using your ReadyNAS storage
system, see the ReadyNAS OS 6 Software Manual, which is available at
http://support.netgear.com/product/ReadyNAS-OS6.
NETGEAR maintains a community website that supports ReadyNAS products. Visit
http://www.netgear.com/readynas for reviews, tutorials, a comparison chart, software
updates, documentation, an active user forum, and much more.
Setup Location
Your ReadyNAS storage system is intended for installation in a restricted access location
(dedicated equipment rooms, service closets, and the like) only.
Keep the following considerations in mind as you install your system:
• Ambient operating temperature. If the system is installed in a closed or multiunit rack
assembly, the ambient operating temperature of the rack environment might be greater
than the ambient temperature of the room. Therefore, consider installing the equipment in
an environment compatible with the maximum rated ambient temperature. See
A, Defaults and Technical Specifications.
• Reduced airflow. Mount the equipment into a rack so that the amount of airflow required
for safe operation is not compromised.
Appendix
• Mechanical loading. Mount the equipment into a rack so that a hazardous condition
does not arise due to uneven mechanical loading.
• Circuit overloading. Consider the equipment’s connection to the power supply circuitry
and the effect that any possible overloading of circuits might have on overcurrent
protection and power supply wiring. Consider equipment nameplate ratings when
addressing this concern.
• Reliable grounding. This product requires reliable grounding to be maintained at all
times. To ensure this, ground the rack itself. Pay particular attention to power supply
connections other than the direct connections to the branch circuit (for example, the use
of power strips).
• Clearance. Leave enough clearance in front of the rack (about 25 inches) to enable you
to open the front door completely and in the back of the rack (about 30 inches) to allow for
sufficient airflow and ease in servicing.

Diskless Storage System
If you purchased a ReadyNAS storage system without a preinstalled disk drive or drives, you
must add at least one disk to your system before you use the system. You can add a 3.5-inch
hard disk drive, a 2.5-inch hard disk drive, or a 2.5-inch solid-state drive to an empty disk bay .
For information about how to install a disk, see
Use only supported SATA hard disk drives (HDDs) or solid-state drives (SSDs) in your
ReadyNAS storage system. If you use disks that are not supported, NETGEAR technical
support will not provide assistance. For a list of supported disks, see the NETGEAR
Hardware Compatibility List at
If you are adding a previously formatted disk to your storage system, see the instructions in
Previously Formatted Disks on page 27.

Power On and Shut Down
This section describes how to power on and shut down your system. If you must shut down
the system, use one of the preferred shutdown methods whenever possible.
Power On
To power on the system:
1. Connect the system to a power supply.
2. Flip the Power switch to the On position.
The Power switch is located on the back panel of the system.
Note: Depending on the system’s last power state, the system might power on
automatically. For more information, see
Power State on page 13.
3. If necessary, press the Power button on the front panel of the system.
The system powers on.
Preferred Shutdown
You can gracefully shut down your system by using the Power button or the ReadyNAS local
admin page.
For information about how to gracefully shut down your system using the ReadyNAS local
admin page, see the ReadyNAS OS 6 Software Manual, which is available at
http://support.netgear.com/product/ReadyNAS-OS6.
To gracefully shut down your system using the Power button:
1. Press the Power button on the front panel of the system.
The Power LED blinks, prompting you to confirm the shutdown.
2. Press the Power button again.
The system shuts down gracefully.
Forced Shutdown
Perform a forced shutdown only if the storage system is not responding.
To perform a forced shutdown:
Flip the Power switch to the Off position.
The Power switch is located on the back panel of the system.
The system shuts down.
ReadyNAS 2120

NETGEAR ReadyNAS OS 6 Rack-Mount Storage Systems
Power State
If the power supply is interrupted due to a power failure, the system returns to its last state
once 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. During the 10-minute time-out period, you
can choose to power off the storage system without causing any data loss, and the
factory default process is canceled. If you choose not to power off the storage system,
after the 10-minute time-out period, the factory default process 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-RAID2.
Note: To start the factory default process immediately, press the Reset
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 using the
storage system’s LEDs. Contact a NETGEAR technical support representative to
interpret memory test results.

• 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, which
you can view using the local admin page. For more information about viewing the system
logs, see the ReadyNAS OS 6 Software Manual.
To access the boot menu:
1. Power of
2. Using a straightened paper clip, press and hold the Reset button.
3. Press the Power button on the front panel of the system.
The system powers on.
4. Continue to press the Reset button until the Power button is solid green and the Error LED,
LAN 1 LED, and LAN 2 LED are blinking.
5. Press and release the Reset button to scroll through the boot menu modes.
The storage system shows the boot mode options using the LEDs, as described in the
following table:
