5. Drive activity LED

A drive activity LED is designed into the INI-9100U/9100UW 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. The INI- 9100U/9100UW host adapter has a four pin connector located at J3 (refer to figure 3-1) to accommodate an 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 theses circumstances, it is possible to have one of the two computer systems turned off. Under theses conditions, the INI-9100U/9100UW has a jumper JP1, 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.
