Using the LSIU40SE

TERMPWR through a blocking diode and a self-resetting 1.5 A short
circuit protection device. The on-board LED lights when TERMPWR is
shorted. Separate switches for each channel allow user override of
termination.

A 40 MHz oscillator is installed on the LSIU40SE to provide the clock
frequency to the LSI53C876 that is necessary to support Wide Ultra
SCSI transfers of up to 40 Mbytes/s.

1.3.3

Ultra SCSI

The LSIU40SE fully supports Ultra SCSI as well as Fast SCSI
simultaneously. Ultra SCSI is an extension of the SCSI-3 family of
standards that expands the bandwidth of the SCSI bus, allowing faster
synchronous data transfers.

Special SCSI cables are specified for operation with Ultra SCSI devices.
You must consider the total number of devices and the length of the SCSI
bus when setting up your system. See

Chapter 2, “Installing the

for a more detailed explanation of SCSI bus connections.
