FCC & DOC COMPLIANCE
FederalCommunications CommissionStatement
This device complies with FCC Rules Part 15. Operation is subject to the following
two conditions:
• This device may not cause harmful interference, and
• This device must accept any interference received, including interference that
may cause undesired operation.
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential installa-
tion. This equipment generates, uses and can radiate radio frequency energy and, if
not installed and used in accordance with manufacturer's instructions, may cause
harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the interfer-
ence by one or more of the following measures:
• Re-orient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment to an outlet on a circuit different from that to which the
receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
WARNING: The use of shielded cables for connection of the monitor to the graph-
ics card is required to assure compliance with FCC regulations. Changes or modifi-
cations to this unit not expressly approved by the party responsible for compliance
could void the user's authority to operate this equipment.

1. Introduction
1. Introduction
The ASUS PCI-DA2100 is a PCI to SCSI RAID controller specifically designed to
provide RAID 0, 1, 3 or 5 capability to any host system equipped with Little Endian
PCI Local Bus interface. All the RAID functions of ASUS PCI-DA2100 are per-
formed by a 486 CPU coupled with high-speed DRAMs and firmware in Flash
Memory. In effect, it endows the host system with the high performance and fault-
tolerant disk storage operation of RAID technology. It is also an ideal solution for
weaving several hard disks into one contiguous volume.
TheASUS PCI-DA2100 has a comprehensive drive failure management that allows
automatic bad block reassignment when a bad sector is encountered during a write.
Hot-swapping is supported through automatic detection of failed drives, followed
by either automatic background rebuilding onto a spare if a spare is assigned or
manual replacement of failed drive and manually initiated background rebuilding.
And all these failure recovery operations are performed in a way transparent to the
host.
The controller has been designed with the ease of integration and maintenance in
mind. The major features are described in the following section. The ASUS PCI-
DA2100 already includes all the major operational requirements for a RAID sub-
system. The final features of a fully-built RAID subsystem will, however, depend
on the actual components used and the creativity of the integrator.
