ReadyNAS Duo v2 and NV+ v2
Setup Location
Your ReadyNAS Duo v2 or NV+ v2 is suitable for use in a home or small office environment
where it can be freestanding. The small, compact size makes it suitable for sitting on a desk
or on a closet shelf.
Choose a location for your unit that meets these criteria:
• Cables can be connected easily.
• Water or moisture cannot enter the case.
• Airflow around the unit and through the vents in the side of the case is not restricted.
• The air is as free of dust as possible.
• Temperature operating limits are not likely to be exceeded.
• If you are using an uninterruptable power supply (UPS) for protection, the power
cable can be securely and safely connected to the UPS.
System Requirements
Your ReadyNAS Duo v2 or NV+ v2 requires the following:
• Ethernet connection
• Microsoft Windows 7, Vista, XP, 2000, Mac OS, UNIX, or Linux operating system
• Microsoft Internet Explorer 7.0+, Apple Safari, 2.0+, Mozilla Firefox 2.0+, Opera 9.5+,
or Google Chrome 10+ browser
• Hard disk drive or drives from the NETGEAR Hardware Compatibility List; see
http://www.readynas.com/hard_disk_hcl.

Diskless Units
If you purchased a ReadyNAS storage system without a pre-installed hard disk drive or
drives, you must follow this procedure before you use your unit. The following procedure is
illustrated with a Duo v2, but the same steps apply for an NV+ v2.
To prepare a diskless unit for first use:
1. Obtain at least one hard disk drive that appears on the NETGEAR Hardware
Compatibility List.
See http://www.readynas.com/hard_disk_hcl.
If you are using a previously formatted disk, see the precautions listed in Previously
Formatted Disks on page 27.
2. With the unit turned off, insert a disk into a drive bay, as follows:
a. Press the disk tray release latch.
The tray handle pops out.

Getting Started

ReadyNAS Duo v2 and NV+ v2
b. Pull out the disk tray, place the new disk on the tray, and assemble the disk and tray
with the screws that came with your unit.
Make sure that the hard disk connectors face the interior of the disk bay.
c. Slide the disk tray back into the unit and press the handle to secure the disk.
3. Turn the unit on.
4. If you are using previously formatted disks, perform a factory reboot.
For more information, see Boot Menu on page 16 and Previously Formatted Disks on
page 27.
Note: Note: This process erases all data and formats the disk as
X-RAID2TM. If you are using a previously formatted disk that contains
data you want to preserve, you must move the data to an external
drive before using the previously formatted disk in your ReadyNAS
unit.
The factory reboot process can take up to 30 minutes while your unit tests and formats
the disk, installs the operating system, and creates a volume. This process can take up to
30 minutes; you can follow the progress in RAIDar. For more information about RAIDar,
see the ReadyNAS RAIDiator 5.3 for Home Software Manual, which is available at
http://www.readynas.com/documentation.
If you are installing multiple disks at the same time, they must synchronize. This might
take several hours, depending on the disk size. You can continue to use your ReadyNAS,
although access is slower until the volume synchronization finishes.

Status Information
You can obtain information about the status of your unit by reviewing the indicators listed in
the following table.
Indicator Description
Power button and LED Press this button to turn on the ReadyNAS. The LED has these states:
• Blinking. Booting or shutting down
• On. Powered on
• Off. Powered off
Disk LEDs (1, 2) Each disk bay has an LED associated with it on the front panel of the unit. The
disk LEDs have these states:
• On. Power is on and the disk is operating normally.
• Blinking. The disk was removed, failed, or is resynchronizing.
• Off. The disk bay is empty.
Disk activity LED The disk activity LED has these states:
• Blinking. A disk is active.
• Off. No disks are active.
Rear panel Ethernet port
LEDs Two LED status indicators are built into this port, one green and one amber. They indicate port speed and activity as follows:
• Green on, amber off. 1000 Mbps connection speed, no activity
• Green blinking, amber off. 1000 Mbps connection speed, activity
• Green off, amber on. 10 Mbps or 100 Mbps connection speed, no activity
• Green off, amber blinking. 10 Mbps or 100 Mbps connection speed, no
activity
• Green off, amber off. No connection
System Shutdown
You can shut down your unit in these ways:
• Using the Power button:
• Preferred shutdown. Press the Power button twice to initiate a graceful shutdown.
• Forced shutdown. If the unit is not responding, unplug it.
• Using the ReadyNAS Dashboard. For information about using the ReadyNAS
Dashboard to shut down your Duo v2, see the ReadyNAS RAIDiator 5.3 for Home
Software Manual, which is available at http://www.readynas.com/documentation.

ReadyNAS Duo v2 and NV+ v2
Boot Menu
Use the boot menu to restart or troubleshoot your ReadyNAS unit. Your unit 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, then
begins a 10-minute time-out period waiting for RAIDar. During the 10-minute time-out
period, the system can be powered off safely without causing any data loss. After 10
minutes, or if you select the factory default option with RAIDar during the time-out period,
the factory default process begins.
WARNING!
The factory default reboot process resets the unit to factory
settings, erases all data, resets all defaults, and reformats the disk
to X-RAID2.
• 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 unit, 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 instructed to do so by a NETGEAR Technical Support representative.
• Skip volume check. After a system crash, the system tries to scan and fix the volume
using a file system check. If several problems are found on a disk, this process can stall,
causing the system not to boot. Use this option to skip the scan and let the system boot.
WARNING!
Use the skip volume check boot mode only when instructed to do
so by a NETGEAR Technical Support representative, otherwise
data loss might occur.
• Memory test. Performs a memory test. The pass or fail result is reported using the unit’s
LEDs. Contact a NETGEAR technical support representative to interpret memory test
results.
• Disk test. Performs an offline full disk test. This can take 4 hours or more, depending on
the size of your disks. Any problems are reported in the RAIDar discovery tool.
