Figure 9. Dip Switch Default Settings

If you need to change any of the factory-default settings, you must first power-cycle
the drive by turning it off and then on again, or a SCSI Bus Reset command must be
received for the new switch settings to take effect.
If the default settings are correct for your system,
go to: "Mounting the Drive" on page 27.
Otherwise, refer to the appropriate following section, make the changes, then go to:
"Mounting the Drive" on page 27.
The three switches S1, S2 and S3 correspond to the SCSI device address
identification bits 0 (LSB) through 2 (MSB), respectively.
The default setting is SCSI device address 0 (S1 through S3 = OFF).
Be sure that no other device on the SCSI bus has the same SCSI address.
S4 = ON disables the MRS check
S4 = OFF enables the MRS check
The default is MRS disabled (S4 = ON).
If S4 is ON, the drive writes or reads both MRS and non-MRS 4-mm media. If S4 is
OFF, the drive only writes to MRS media. The drive reports a check condition if the
media is nondata grade. The Sense Key is 07, Data Protect. The additional Sense
Code and qualifier is 30/00, incompatible media installed.
