Hardware Installation

5Drive 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.

6Multiple 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.

7Close 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.

8Host 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.
