Nexsan Unity Storage Expansion Reference Guide v. 7.0 Unity 4

About this document
This Unity Storage Expansion Reference Guide provides information and steps for installing and
connecting the following Nexsan Unity Storage Systems:
Nexsan UNITY3300™ Storage System
Nexsan UNITY7900™ Storage System
Nexsan Unity NV10000™ Storage System
Nexsan Unity Storage US224™ Expansion
Nexsan Unity Storage US316™ Expansion
Nexsan Unity Storage U2G460™ Expansion
This Reference Guide assumes that you are familiar with Serial Attached SCSI (SAS) technology, computer
hardware, data storage and network administration terminology and tasks.
Because this guide provides information that can be used to manage one or more Nexsan Unity Storage
Expansions, the generic term “storage system” is used to refer to the controller, disk drives, and expansions
being used together for data storage.
Many of the terms and concepts referred to in this Reference Guide are known to computer users by
multiple names. This terminology is used:
I/O Controller (also known as an I/O module, controller or controller node)
Disk drive (also known as hard disk drive (HDD) or hard disk, and solid state disk drive (SSD)
HBA (also known as Host Bus Adapter or SAS Adapter)
Audience
This guide has been prepared for the following audience:
IT system administrators
Engineers
Technicians
Any qualified NST/Unityadministrator.

Safety notices
Always observe the following precautions to reduce the risk of injury and equipment damage:
Computer components and disk drives are sensitive to static discharge. Take precautions to discharge
any electrostatic charge from your person before and while handling components with your hands or any
tools. Use an anti-static wrist-strap.
The system only be installed in a clean, dry environment. The operating temperature is 10º to 35º C (50º
to 95º F), with operating relative humidity at 20 to 95%, non-condensing.
Do not install hardware in an enclosed cabinet or other small area without ventilation.
Ensure correct lifting methods are used when handling hardware. Special care should be taken when
removing hardware from its packaging and positioning it into its required location. When lifting hardware,
two people at either end should lift slowly with their feet spread out to distribute the weight. Always keep
your back straight and lift with your legs.
When installing the system as a rack-mounted component, ensure that all Nexsan-supplied mounting
fixtures are secure. All bolts and screws should be fully tightened. Failure to comply with this may result
in the unit not being fully supported in the rack and could lead to the product falling from the rack causing
personal injury or falling onto other rack components.
Ensure that the rack is sufficiently stable by having wall anchors and/or stabilizing legs, and that the floor
supporting the rack has sufficient strength for the overall weight loading.
Only a fully-trained Service Engineer is authorized to disassemble any other part of the hardware, and
then only when the hardware is powered off.
The system has multiple power connections; as a result, you must remove all power leads to completely
isolate the power and always use the IEC power cords which are supplied with the system.
CAUTION: All NexsanUnity Storage Systems are hot-pluggable. However, new expansions must
be powered on AFTER you connect it to the existing system.
