In the drive, preventive measures are taken to guard against
dust. It is unnecessary to clean the optical lens of your
drive. Using a lens cleaning cartridge may damage the
drive.

Cooling Requirements

Forced-air cooling is required throughout the drive,
preventing overheat of the drive mechanism and electrical
components. Forced-air cooling must be provided as a
system integration.

This maximum temperature is applicable to all operating
conditions specified in this manual.

Measuring Point Maximum Temperature

Disk Cartridge 55 °C (131 °F)

The temperature conditions specified in this
manual must always be met for the SMO-F561 to
function properly.

* This pin is NOT directly connected to the GND. Do not use this pin as

GND. The SMO-F561 drives the signal to GND level depending on the
functional switch setting. Otherwise, the signal is not driven to GND
level.

WARNING: Write cache is enabled as default
setting. The integrity of the buffer memory content
is not guaranteed through power cycling.

Caution: “Disable Write Cache” setting works as an “OR”
function with the optional dip switch setting.

Caution: When the Fast SCSI function is used, it is
recommended that the host system and SCSI cables should
conform to the Fast SCSI.

SCSI Terminator

The SMO-F561 features an internal SCSI bus terminator.
When the drive is connected at the end of the SCSI chain,
functional switch #11 (Enable Terminator) may be used to
terminated the SCSI connection.

For a single ended cable, 50-signal conductor flat cable or a
25-signal twisted cable can be used. The cable length shall
not exceed six meters.

Optional Switch Setting

The SMO-F561 features Optional Switch S501 and S502.
These two optional dip switches allow the user to set the
drive configurations.
