5 Getting Started Host Adapter and the SCSI Bus I/OHIGHWAY is a bus mastering host adapter which works with the host computer to provide control for the SCSI bus. By daisy chaining peripheral devices together, up to seven devices can be linked with I/OHIGHWAY. The host adapter can be placed in any 2 standard PCI slot on the bus. SCSI bus preparation Each peripheral device attached to the SCSI bus can either be an internal or external device. Each peripheral has a specific device ID, commonly

6 Getting Started I/OHIGHWAYs SCSI termination can be set to auto-termination or programmable mode via the SmartSCSI Setup Utility. This feature allows the operator to switch the auto- termination On or Off. If auto-termination is switched off, the operator can manually program termination for the host adapter. There are three ways to manually control terminating the host adapter on the SCSI bus (see TABLE 1). SCSI Devices Configuration SCSI Channel Termination 1 Internal Devices Only ON 1 Ex

7 Hardware Installation Installation Basics The internal cable permits connection of multiple internal devices. SCSI devices that are connected to the internal connector are installed inside the host computer enclosure. The external connector is accesible through the D-shell connector at the back of the 3 host system and is designed to connect devices outside the host system enclosure. The following table has connector details of I/OHIGHWAY. Internal External Maximum SCSI Product Connector Conne

8 Hardware Installation 3 Inserting the host adapter Orient the host adapter for installation so that the external connector is facing the back of the system unit and align the card with the PCI connector on the system unit (see FIGURE 3). Holding the adapter by the mounting bracket and the card edge, match up the card edge connector with the PCI host computer socket and insert the card into the socket. Once the connector is in the PCI expansion slot socket tighten the mounting bracket screw to

9 Hardware Installation When attaching FastSCSI devices, use the 50-pin FastSCSI cable connector on the host adapter. Align the internal cable into the host adapter and the other cable connectors in a similar fashion into the other SCSI device connectors as described in the appropriate manufacturers instructions. FIGURE 4 Connecting the 50-pin internal flat ribbon cable 4b Installation of external SCSI cables Installation of external SCSI cables can be performed after the cover has been close

10 Hardware Installation 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 adapters 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

11 Hardware Installation 9 System startup The newly installed SCSI bus is now ready to power up. Switch on peripheral and host computer system power. The system monitor should display the following information, but may vary, based on the system BIOS manufacturer. The normal Power-On Self Test and memory test procedure. The host adapter sign on message including a list of attached SCSI devices. The list should match the peripheral devices attached to the bus. In most cases the host computer

13 Host Adapter Setup Running the SmartSCSI Setup Utility To start the SmartSCSI Setup Utility, verify that all devices attached to the SCSI bus are powered up when the host computer system is turned on. Once the power switch has been turned on and the system begins its on screen power up sequence, the Initio banner 4 will be displayed for a brief period. During this time the Initio SmartSCSI Setup Utility is accessible by pressing the key and the key at the same time. When displaye

14 Host Adapter Setup DOS Space > 1 GB. Using this option allows for single disk capacities to be extended up to 8 GBytes (yes). Please refer to the Appendix titled DOS Space > 1 GB for further information on this feature. (NO) DOS limits the number of cylinders per drive to 1024. The host adapter defines head and sector usage to 64 heads and 32 sectors. This format allows for maximum capacity of 1 gigabyte per disk storage. (YES) The upper limit can be extended from 1 GByte to 8 GBytes b
