SCSI Controller
The SCSI version of the server board includes an embedded Adaptec
AIC-7899W / 7902W controller providing dual Ultra160/Ultra 320* Low
Voltage Differential (LVD) SCSI channels.
The SCSI bus is terminated on the server board with active terminators
that cannot be disabled. The onboard device must always be at one
end of the bus. The device at the other end of the cable must also be
terminated. LVD devices generally do not have termination built-in and
need to have a termination source provided. Non-LVDs devices
generally are terminated through a jumper or resistor pack on the
device itself..
Note: Ultra 320 only for AIC-7902W
