Setup guide

Establishing Ideal Environmental Conditions
The following guidelines describe the ideal environmental conditions for your disk array to function properly.
Ensure these conditions are met:
■ Room temperature and ambient humidity are at acceptable levels.
■ The disk array is at room temperature before operating.
■ The environment is clean and dust-free.
■ Disk array fans are not obstructed. Do not drape anything, such as a jacket or blanket, over any part of
the system.
■ There is good air circulation.
■ The environment has minimal vibration and humidity.
■ Electromagnetic noise is minimal by separating digital data and power cables from analog audio cables
and running them in different cable ducts.
■ The power requirements of the system are met by your electrical installation.
■ Any cable ties you use to bundle cables together are slack enough to prevent damage to the wires inside
the cables, and any loops in optical cables are relaxed enough to prevent damage to the optical fibres
inside the cables (for example, no smaller than two centimeters in diameter). Damage to wires or optical
fibres can render cables unstable or completely unusable.
Avoiding Electrostatic Discharge
By eliminating the possibility of electrostatic discharge, you ensure a safe work environment. As well, disk
array components are less likely to be damaged. The following safety guidelines minimize the possibility of
electrostatic discharge.
■ Power your system on and off according to the procedures in the section Powering Up and Down on
page 12.
■ Using a grounded static wrist strap, attach the strap's alligator clip to any grounded metal surface on the
disk array enclosure and place the wristband on your wrist.
■ Stand on a conductive rubber mat.
■ Do not handle the boards for the disk arrays or workstations unnecessarily.
■ Read and observe warning labels on enclosures and drives.
■ Call Customer Support for repair/replacement of disk drives or circuitry within the enclosure by using
one of the methods listed in Contacting Customer Support on page 3.
NOTE The power supplies for all Stone Direct disk arrays are universal, and therefore automatically detect the
correct voltage for your country.
Powering Up and Down
Powering your system up or down should be done in a proper sequence. This will ensure that the system
functions properly.
