indicates when the termination power was subjected to an over current
condition causing the self-resetting current limiting device (circuit
breaker) to trip.
A 40 MHz oscillator is installed on the A5150A card to provide the clock
frequency necessary to support Wide Ultra2 SCSI transfers of up to 80
MBytes per second.
The Wide Ultra2 SCSI Interface
The adapter card has full support for Wide Ultra2 SCSI. This interface is
an extension of the SCSI-3 family of standards that expands the
bandwidth of the SCSI bus to allow faster synchronous data transfers,
up to 80 MBytes per second. Wide Ultra2 SCSI provides a doubling of the
data rate over the Ultra2 SCSI interface, increases the possible cable
lengths, and also allows a larger number of devices on the cable than
Ultra2 SCSI interfaces.
Special SCSI cables are specified for operation with Wide Ultra and
Ultra2 SCSI devices. You must consider the total number of devices and
the length of your SCSI bus when setting up your system. The section
“Connecting the SCSI Peripherals” on page 27 provides a more detailed
explanation of SCSI bus connections.
