Protecting Equipment and Data
ESD (Electrostatic Discharge) Precautions
To avoid damaging computer components and accessories when
installing or removing the 3ware RAID controller card, follow
standard electrostatic discharge (ESD) precautions:
„ When your computer case is open and its internal parts are
exposed, do not touch any internal part unnecessarily.
„ Always wear a grounded strap or work on an ESD-protective
mat.
„ Do not remove the 3ware SATA+SAS controller card from its
protective bag until you are properly grounded.
„ Handle the 3ware RAID controller card by its edges or by the
metal bracket.
„ Do not touch any pin, contact, lead or component on the 3ware
RAID controller card.
Heat Sink Warning. Do not replace the factory-installed
heat sink shipped with the 3ware 9750 SATA+SAS controller
cards. Replacing the heat sink will alter thermal
characteristics and cooling requirements and may cause the
controller to fail. Replacing the factory-installed heat sink will
void the warranty.
Back up your data! Creating or deleting disk arrays
destroys existing files on the member drives. If your drives
contain valuable data, back them up and save the data
elsewhere before attaching the drives to the controller.
