Personal Safety When Installing the 9750 Card in
Your Computer
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.
Warning. We recommend you plug your system into a surge
suppressor or UPS (uninterruptible power supply) and during
an electrical storm, we recommend disconnecting all phone,
network, and power cables.
Warning! High voltages may be found inside computer
equipment.
Before installing any of the hardware in this package or
removing the protective covers of any computer equipment,
turn off power switches and disconnect power cords. Do not
reconnect the power cords until the hardware is installed and
the system cover is closed.
Heat Sink Warning. Do not replace the factory-installed
heat sink shipped with the 3ware 9750 SATA+SAS controller
cards. Replacing the heat sink alters the thermal
characteristics and cooling requirements and may cause the
controller to fail. Replacing the factory-installed heat sink
voids 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.
