5 Drive activity LED
A drive activity LED is designed into the host adapter to indicate when a data
transfer is being made. Connection to the LED is optional and cabling is not in-
cluded with this kit. Each host adapter has one four-pin connector. Please refer to
the host adapter’s illustration ( FIGURE 1) for the LED connector that will accomodate
the LED cable.
6 Multiple Initiators
Under some circumstances multiple initiators can be used on a single SCSI bus. The
bus is configured to have more than one host adapter inserted into at least two
distinctly different computer systems sharing peripheral devices. In these circum-
stances, it is possible to have one of the two computer systems turned off. Under
these conditions, the host adapter has a jumper that can be enabled (closed) to set
the active on-board termination on all the time, regardless of whether power is
applied or not. The host adapter is shipped without the jumper installed and need
not be changed in most cases.
7 Close the cover on the host computer
Visually inspect the configuration you have installed to verify that all cables have
been inserted correctly. Close the cover on the host computer. The hardware
installation for the host adapter is now complete.
8 Host computer configuration
Most computer manufacturers with a PCI bus automatically configure the add on-
card or host adapter I/O Port address, IRQ Channel and BIOS address. If this is not
the case with your computer system, you will need to manually configure your
system.
There are two means of configuring the PCI bus from the host computer system:
1. Setting jumpers on the host system motherboard.
2. Setting CMOS BIOS incorporated into the host system.
You will need to refer to the host computer system documentation to complete PCI
bus activation and setup.
If the host system will be using a SCSI device to provide system boot capability, then
the system CMOS drive type settings may need to be changed. Under some condi-
tions the system will expect the boot disk to be an IDE drive. This must be changed
in order to boot from a SCSI device.
