Safety noticesThis guide covers the Nexsan E32XV™/Nexsan E18X™/E18XV™digital storage expansion units only. Referto the relevant product manuals for information on other Nexsan storage or expansion units and other Nexsanproducts mentioned in this guide.Always observe the following precautions to reduce the risk of injury and equipment damage:

WARNING: There is a risk of ELECTRIC SHOCK if Nexsan E-Series™ components are removedor tampered with when unit power is on. Only a trained operator may remove certain customer-replaceable units (CRUs). The Nexsan E-Series™ storage units include the following CRUs:

Power Supply modules

RAID Controller and Expansionmodules

Disk drives

Fanmodules

Computer components and disk drives are sensitive to static discharge. Take precautions to dischargeany electrostatic charge from your person before and while handling components with your hands or anytools. Use an anti-static wrist-strap.

Ensure correct liftingmethods are used when removing the unit from its packaging and positioning it into itsrequired location. When lifting the system, two people at either end should lift slowly with their feet spreadout to distribute the weight. Always keep your back straight and lift with your legs.

When removing the unit from the packaging, DONOT lift the unit by any plastic parts or module handles onthe chassis. Doing somay cause damage to the chassis or to internal components, or both. Lift the unitONLY by the bottom edges of the chassis, using safe lifting practices.

The unit should only be installed in a clean, dry environment. The operating temperature is 5º to 30º C (41ºto 86º F), with operating relative humidity at 20 to 80%, non-condensing.

Do not install the unit in an enclosed cabinet or other small area without ventilation.

When installing the unit as a rack-mounted component, ensure that all Nexsan-suppliedmounting fixturesare secure. All bolts and screws should be fully tightened. Failure to comply with this may result in the unitnot being fully supported in the rack and could lead to the product falling from the rack, causing personalinjury or damage to other rack components.

Ensure that the rack is sufficiently stable by having wall anchors and/or stabilizing legs, and that the floorsupporting the rack has sufficient strength for the overall weight loading.

The cordset specification for the Nexsan E32XV™/Nexsan E18X™/E18XV™ in North America is USAIEC C13 to IEC C14, rated 125V/15A. When applying power to the unit, use ONLY the IEC power cordsoriginally supplied with it. Do NOT use other power cords, even if they appear identical to the suppliedcords.

Only a fully-trained Service Engineer is authorized to disassemble any other part of the unit, and then onlywhen the unit is powered off.

All Nexsan E-Series™Storage Systems havemultiple power connections; as a result, youmust removeall power leads to completely remove power from the unit.

Nexsan E-Series™Storage Systems do not have power switches. Do NOT attach the power cords untilthe unit is fully installed, with all disk drives in place.

RAIDRedundant Array of Independent Disks. Asystem usingmultiple hard drives organized intoa single logical unit for the sharing or replicationof data in order to increase data integrity, fault-tolerance, and throughput. Also referred to as aRAID set. RAIDs are organized intoRAID levels, which describe their architectureand configuration.

RAID ControllerA hardware device, software program, orcombination of the two whichmanages thephysical disk drives in a RAID and presentsthem as a single logical unit to attacheddevices. The RAID Controllers in Nexsanstorage units are hardwaremodules. NexsanRAID Controllers also provide connections forsystem administration and configuration.

RAID levelA numeric indicator of the architecture used by aRAID. RAIDs can be built using anycombination of striping, mirroring, and parity.The levels are numbered from 0 through 6.SomeRAID levels can also be combined, andthese configurations are usually referred to witha two-digit number. For example, RAID 10 =RAID 1 + RAID 0.
