A Initial setup information The general information beginning on this page applies to all of the Elite 23 drive models. After reading the general information topics, refer to the appropriate drive-specific section listed below for additional information about configuring and installing your particular model. Drive models ST423451N ST423451W ST423451WD All drives (LED indicator connections) Page 34 38 42 General information The following general information topics are discussed: · · · · · · · · SCSI ID jumpers Drive termination Terminator power Interface drivers and data path width notes Other applicable jumper options Providing adequate cooling Mounting the drive and connecting cables Formatting the drive Elite 23 Installation Guide, Rev. A 17 SCSI ID jumpers Each device on the SCSI chain must have a unique SCSI ID. The host system's SCSI controller usually uses the ID that has the highest priority interrupt in the SCSI I/O system. The lower priority SCSI IDs are normally used for other SCSI devices such as this Elite disc drive. Other controllers do not allow this so be sure to refer to your system or controller user's manual for details about its requirements for proper SCSI device installation. This drive is a SCAM (SCSI Configured Auto Magically) compliant drive. If the system into which you are installing this drive requires SCAM compliant drives, you do not need to be concerned about the drive ID jumper settings, as the system automatically assigns your new drive the ID it wants it to have. Setting the drive ID doesn't hurt anything, but is not necessary in a SCAM compliant system. To change the SCSI ID, refer to the appropriate drive section for your model. If, after completing the installation process, the drive's LED does not show on/off activity when the host is trying to communicate with the drive, a duplicate SCSI ID may be the problem. A the case, change the ID so that each device on the SCSI chain has its own unique ID. Also check your system or controller user's manual to ensure that you have not violated its SCSI ID numbering recommendations. Drive termination If you are installing a Elite 23 drive in a system that has other SCSI devices installed, terminate only the end devices on the SCSI chain. A SCSI "device" is any disc drive, scanner, tape backup unit, or other piece of hardware connected to your system using the SCSI bus. The top example in Figure 2 shows an internal hard disc at one end of the SCSI bus with the SCSI controller at the other end (both are terminated). The bottom example shows two additional SCSI devices connected externally. This means the SCSI controller is no longer on the end of the SCSI chain and should not be terminated. Some controllers prefer to remain terminated even if they are in the middle of the chain. Also, some controllers treat the internal and external chains as separate logical buses. [. . . ] You will not normally need to change this option and can leave the drive configured as it was shipped from the factory.

J4A Pin 1 J01 J4B J4B Pin 1 Spinup Delay Option (DS) Immediate spinup (if the Start Command option jumper is disconnected) Spinup delay equal to the SCSI Bus ID multiplied by 12 seconds (if the Start Command option jumper is disconnected). Start Command Option (ME) Start spindle according to the Spinup Delay option jumper. [. . . ]
