SEAGATE  ST39140/36530/34520N/W/WC  JUMPER SETTING

 Jumper Settings
 ===============

 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 in the SCSI I/O system. This is always ID7.
 ID0 is lowest priority in an 8-bit I/O system. ID8 is lowest priority
 in a 16-bit I/O system. The lower priority SCSI IDs are normally
 used for other SCSI devices such as this Medalist disc drive.
 Note. Most SCSI controllers (host adapters) allow you to skip a
 SCSI ID. For example, you can have ID0, ID1, and ID3 (skipping ID2).
 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.

 Note. 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. The system may or
 may not use the existing drive ID jumper settings. Setting the drive
 ID doesn't hurt anything, but is not necessary in a SCAM compliant
 system.

 The Medalist disc drives are factory set with the SCSI ID set at 0.
 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. If this is
 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 Medalist 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.

 Note. 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. This
 means you may need to terminate both the first and last devices on
 both logical buses to achieve proper termination. If necessary, refer
 to your system or controller documentation to see how this is handled
 in your particular system.


 Terminator power
 ----------------
 You usually will not need to change this option and can normally
 leave the drive configured as it was shipped from the factory. For
 information about how to change the terminator power option on
 your drive, refer to the appropriate drive-specific section.
 I/O circuits and data path widths W and WC models have a wide
 (16-bit) SCSI data bus rather than the standard (non-wide) 8-bit SCSI
 data bus; however, you can use these wide drives on a standard
 (non-wide) 8-bit data bus using a terminated 68-pin to 50-pin SCSI
 cable.

 For devices having differential I/O circuits, a maximum cable
 length of 25 meters (82 feet) is allowed. A maximum of 8 devices
 can be connected on an 8-bit wide data bus, and a maximum of 16
 devices can be connected on a 16-bit wide data bus.

 N drives
 ---------
 Terminating the drive
 N model drives are terminated with permanently mounted IC active
 terminators. If you install one of these drives and it is not
 on the end of the SCSI bus, disable the terminators by removing
 the jumper TE from pins 15 and 16 of connector J2. If you install
 the drive on the end of the SCSI bus, enable termination by
 installing a jumper on pins 15 and 16 of connector J2.


 Terminator power
 ----------------
 There are four possible terminator power (TP) configurations for
 N model drives. You will not normally need to change this option and
 can leave the drive configured as it was shipped from the factory.


 W/WD drives section Setting the SCSI ID jumpers
 -----------------------------------------------
 Use the J6 jumper block to set the SCSI ID. To change the SCSI ID,
 install jumpers on the appropriate pins. Optional connections to
 switching circuits in host equipment are provided on J1 auxiliary to
 set the SCSI ID.


 Terminating the drive
 ---------------------
 W model drives are terminated with permanently mounted IC active
 terminators. If you install one of these drives and it is not
 on the end of the SCSI bus, disable the terminators by removing
 the jumper TE from pins 15 and 16 of connector J2. If you install the
 drive on the end of the SCSI bus, enable termination by installing a
 jumper on pins 15 and 16 of connector J2.

 Note. Use active (ANSI SCSI-2 Alternative 2) terminators when
 terminating the bus.


 Terminator power
 ----------------
 There are four possible terminator power (TP) configurations for
 W model drives. You will not normally need to change this option and
 can leave the drive configured as it was shipped from the factory.


 WC drives
 ----------
 WC/DC drives section Setting the SCSI ID jumpers
 The SCSI ID for WC model drives is normally set over the SCSI
 bus by the host system using connector contacts 39 (ID0), 40
 (ID2), 79 (ID1), and 80 (ID3). Users need not install jumpers to
 select SCSI ID.


 Terminating the drive
 ---------------------
 WC model drives do not have internal terminators or any other
 way of adding internal termination to the drive. External
 termination for these drives is normally supplied by the host
 equipment when termination is required.
