Precautions

Static electricity can damage the components inside a system base unit or a RAID disk array
cabinet. To minimize the possibility of electrostatic discharge, observe the following
precautions when working with the internal components of a system or a cabinet.
u
Touch the bare metal of the base unit or cabinet to discharge any accumulated static
charge.
u
Avoid servicing the system in areas known to have electrostatic problems, such as on
rugs and carpets.
u
Handle all printed circuit boards as little as possible and by the edges only. Leave the
boards in their protective packaging until you install them.
u
Do not drop, jar, or bump the disk drives. Handle all disk drives by the edges, and avoid
touching connector pins or printed circuit board components.
u
Always turn off power to the system base unit before turning off power to the cabinet,
and leave the power cord connected to maintain ground.
If you do not heed these precautions, your system or replacement parts could be damaged and
your warranty voided.
