DVAS Series | Instruction Manual | Product Introduction
1PRODUCT INTRODUCTION
DVAS Series Digital Video Array is a high speed, fault
tolerant RAID subsystem design. It uses a mid-plane
design to eliminate the problems associated with cable
interconnects. Unlike conventional RAID products, the
DVAS Series disk array uses ATA disk drives to store
RAID data, rather than high cost SCSI or Fiber Channel
disks. Its advanced electronic soft-start technology makes
hot-swappable ATA drives very reliable.

2UNPACKING
2.1 Safety Concerns
•Computer components and disk drives are
sensitive to static charge. Take precautions to
divert any electrostatic charge from your person
before and while handling the components with
your hands or any tools.
•Before removing Controllers or Power Supplies,
ensure that the system is powered down and
disconnected from the main socket.
• Ensure correct lifting methods are used when
handling the DVAS Series disk array. Special
care should be taken when removing the
DVAS Series disk array from its packaging and
positioning it in the required location.
• When installing DVAS Series disk array as a
rack-mounted component, ensure that all
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
dropping out of rack or falling onto other rack
components.
•EMC Regulations require that all data and
network cables be the shielded type. Special
care should be taken to ensure that the network
cable is shielded and that the shield is connected
at both ends.
CAUTION: Lithium Battery
Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type
recommended by the manufacturer. Dispose of used
batteries according to the battery manufacturer’s
instructions.
WARNING:
Electrostatic-sensitive device. Use
proper CMOS/MOSFET handling
precautions to avoid electrostatic
discharge.
NOTE: Grounded wrist straps must be worn and proper ESD
safety precautions observed when handling the electrostatic-
sensitive printed circuit boards.
