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.
