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, consideration should be given to
installing the equipment in an environment compatible with the maximum rated ambient
temperature. See Appendix 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.
•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 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 Add a Disk on page 19.
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 http://www.netgear.com/readynas-hcl.
If you are adding a previously formatted disk to your storage system, see the instructions in
Previously Formatted Disks on page 17.
