Basic Operational Set-Up

Following is a description of a sample operational set-up:
PCI-Ultra2 SCSI
RAID Controller
Only use Ultra2 (LVD) twisted SCSI cables and Ultra2 (LVD) SCSI
terminators.
Drives connected to channel 0 and/or 1.
SCSI nodes on the same channel have unique ID number. The
SCSI ID 7 is reserved for the ASUS PCI-DA2200 adapter and thus
no drives should use ID 7.
Both ends of all SCSI cables are properly terminated. Terminate
the SCSI cable by installing an external terminator on the end
connector. The terminators embedded in ASUS PCI-DA2200
should be enabled. The default state of terminators embedded on
ASUS PCI-DA2200 controller are enabled and can be changed by
running RAIDMAN.EXE or configured in the ASUS PCI-DA2200
BIOS settings
Both SCSI drive channels on ASUS PCI-DA2200 are Ultra2 Wide
SCSI LVD channels, only connect Ultra2 Wide LVD devices to the
drive channels.
Ultra2 Wide SCSI (LVD) is backward compatible with Ultra Wide
SCSI devices (Single-ended). However, any Singled-ended devices
connecting to an LVD bus will cause all the other LVD devices on
the same bus switch back to Single-ended mode. The cable length
will also be limited to Single-ended standard instead of LVD
standard, if any Single-ended devices connecting to an LVD SCSI
bus.
