External cable connection
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
included 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.
