ANSI committee X3T9 2 defined the SCSI 1 spec as Document X3 131 1986 SCSI is now an acknowledged and very well standardized multipurpose interface in all its flavors SCSI supports a wide variety of devices including hard disks removable disks magneto optical devices tape drives printers processors WORMs CD ROMs scanners medium changers jukeboxes and communications devices Q What is SCSI 1 A SCSI 1 defined a universal 8 bit I O bus that allows connection of up to 8 devices including the host adapter Every device must have a unique ID in the range of 0 7 SCSI 1 was a high speed bus system compared to the era s existing peripheral devices Q What is SCSI 2 A Although SCSI 1 was the first approved standard it lacked various parameters and definitions This led to SCSI 2 s development and approval before SCSI 1 was even officially approved In 1986 when SCSI 1 was officially approved SCSI 2 already was far along in the development process The official SCSI 2 designation is X3 131 1994 SCSI 2 provided a better formal definition removed some oddities and obsolete items added some extensions and most importantly added the ability to double and even quadruple data transfer speed on the SCSI bus with its Fast SCSI and Wide SCSI options Q What is Fast SCSI A Fast SCSI was defined as an option with SCSI 2 Despite the tendency of the market to define Fast SCSI as different but faster SCSI Fast SCSI is

D 7 cannot be used as this is the host adapter The FFD uses DIP switches to set the ID in a 4 2 1 configuration The sum of the switch values determines the ID For example if you want a hard disk with ID 0 set all three switches to OFF 45 SR 001 01 7L REV 4 0 16 of 22 rn M Systems mua Flash Disk Pioneers FFD 3 5 SCSI Flash Disk User Manual 8 2 4 Solving Installation Problems The problems that arise in most installations are described below Unstable Termination This occurs when there is a passive termination with Fast SCSI devices on the bus Incorrect Termination This occurs when there are too many devices terminated or when the SCSI bus cable ends are not terminated Cables Avoid using homemade short flat ribbon cables with bad contacts or cheap cables Do not mix round cables with flat cables Cable Length Ensure that the cable length is within the limit specified in the standard and avoid using cables that are too long to support the transfer rate Device ID Conflict This occurs when a new device is added with a SCSI ID identical to an existing device on the bus Missing TRMPWR This occurs when the host adapter or at least one of the devices on the SCSI bus does not supply termination power Missing Software Device Driver Some host adapters do not install support for SCSI drives as an expansion BIOS In this case load an additional driver for your operating system after the system boots Note that

13. ermination Configuration When configuring termination the basic rule to remember is termination is required at both ends of the SCSI chain e To install a new device as the last device on one of the sides of the complete cable you must enable termination on the device e When replacing another device that was previously at the end of the cable and is now installed on another connector on the bus you must disable termination on the device e When installing an external SCSI device in a system that has only internal devices you must disable the host adapter s termination using one of the following methods e Using software as with the newer Adaptec e By removing the terminator packs typically three near the host adapter s SCSI connector e By setting a jumper on the host adapter The situation is the same if you previously had only external devices 8 2 3 SCSI ID Configuration When configuring the SCSI ID first locate a free SCSI ID The most effective method is to look at the host adapter boot up message and check for free IDs Adaptec AHA 1540CF 1542CF BIOS 2 01s c 1993 Adaptec Inc All Rights reserved Press lt Ctrl gt lt A gt for SCSISelect TM Utility Target DEC DSP3085S B SD16 Drive C 80h Target UANTUM LP425S 606_ Drive D 81h Q Target TOSHIBA CD ROM XM 3301T S DI ASERSTOR E5 Target In this example ID 2 5 and 6 are free for new devices I
