Maverick 270/540S

   Jumper    Setting Description                      

    A2, A1,     -    These jumpers are used in        
     A0              combination to determine the     
                     drive's SCSI ID [See table 2]    

Table 1

Termination Resistors

One of the requirements of the SCSI bus is that it be properly terminated. If more than one SCSI device is connected to the host, the last device on each end of the bus must be terminated. The Maverick disk drive utilizes two (2) Terminating Resistor packs, when installed these resistors enable termination on the SCSI bus. With the Terminating Resistor packs removed, bus termination is disabled.

At the factory, Quantum configures the Maverick 270/540S hard disk drive with termination enabled; that is, both resistor packs are installed. To disable termination, remove the Terminating Resistor packs.

SCSI-Bus Device Identification (A0 - A2) Jumpers

Used in combination, the jumper settings across pins A2, A1 and A0 determine the Maverick 270/540S hard disk drive's SCSI-bus device I.D. By default, Quantum configures the drive with a SCSI ID of 6; that is, with jumpers installed across the pins labeled A2 and A1, and no jumpers installed across pins labeled A0.

To assign a different SCSI ID, change the jumper settings as shown in Table 2.

   A2        A1        A0      SCSI ID  

   OFF       OFF       OFF        0
