User manual MAXTOR ATLAS III JUMPERS

[. . . ] Atlas III 50-Pin Jumper Settings 50-Pin Jumper Settings The following describes the jumper options and settings available on the Maxtor® AtlasTM III disk drive. For more detail on jumper definitions; please refer to the jumper definition section. [. . . ] Refer to your system or SCSI controller documentation regarding recommendations on SCSI bus termination. * Indicates default jumper setting Jumper LocationsThe Atlas III wide disk drive has two locations where user configurable jumpers are found. The primary jumper block (Front option connector J3) for the Atlas III wide drive is found on the front edge of the disk drive printed circuit board. Using these jumper pins you can establish the various drive configuration options. The secondary option jumper block provides an alternate method for setting primary drive features. The alternate jumper block is located at the 2 of 5 Atlas III rear of the drive and is incorporated into the SCSI cable connector. 68-Pin Jumper Settings Pin 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 35 Signal A3 A2 A1 A0 Key (blank) Spin Up logic_gnd Reserved Busy LED Write Protect Stagger Spin Enable Narrow Disable SyncNeg Disable Parity Disable Attention Customize No pins Term Power Pin 2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 Signal logic_gnd logic_gnd logic_gnd logic_gnd Fault LED logic_gnd Reserved Reserved +5 volts logic_gnd logic_gnd logic_gnd logic_gnd logic_gnd logic_gnd logic_gnd No pins Term Power 3 of 5 Atlas III 68-Pin Jumper Settings Pin 1 3 5 7 9 11 Signal A0 A1 A2 A3 Reserved +5VDC out Pin 2 4 6 8 10 12 Signal Fault LED logic_gnd logic_gnd Busy LED logic_gnd No connect SCSI ID Settings The following table identifies the various SCSI ID values and the jumper positions required to set them.

Maxtor Atlas III was developed by Quantum Corporation prior to its merger with Maxtor. LVD Disable (SE) Enable Single Ended operation SE jumper on Enable auto switch between Single Ended or LVD operation SE jumper off* * Indicates default jumper setting The Atlas III SCA drive does not provide support for any additional options through the use of physical jumper settings. Additional feature options are set through the SCA interface, contact your system manufacturer for details on how to set optional features. The Atlas III SCA provides support for: Stagger Spin, Spin Delay and SCSI ID selection. The Atlas III SCA does not provide support for: Active Termination enable, Termination Power and Write Protect. 1 of 4 Atlas III 80-Pin Jumper Settings Jumper Locations The Atlas III SCA disk drive has only one location where user configurable jumpers are found. The jumper block for the Atlas III SCA drive is found on the disk drive printed circuit board near the SCA cable connector. SCSI ID Settings The Atlas III SCA drive does not provide for physical configuration of the SCSI ID. Maxtor, formerly Quantum, disk drives that utilize the 80-pin SCA connector do not require any jumper configuration for SCSI ID. Systems that use SCA connections, typically, autoconfigure the SCA device. [. . . ] This jumper block is found on the printed circuit board at the rear of the drive and is near the SCSI cable connector. 28-Pin Secondary Option Connector Pin 1 3 5 7 9 11 13 15 17 19 Signal A0 A1 A2 Fault LED Busy LED +5VDC out Delay Spin Stagger Spin Write Protect Spindle Sync Pin 2 4 6 8 10 12 14 16 18 20 Signal logic_gnd logic_gnd logic_gnd key (blank) Spindle Sync unused logic_gnd logic_gnd logic_gnd logic_gn The drawing above displays the jumper block physical location and pin definitions.
