Safety Considerations
■ Power supply
• Be sure to use +5 V, +12 V DC.
Damage Prevention
■ Do not subject the drive to shock or vibration
■ Location requirements
Careful consideration should be given to the following in
selecting a site to install or store your drive.
Avoid the following conditions:
• High humidity
• High temperatures
• Direct sunlight
• Dust
• Strong vibration
• Wide temperature fluctuations
■ Moving the drive
Be sure to remove the disk cartridge when the drive is not
being used. Also never move or transport the drive with the
disk cartridge still inserted.
■ If problems occur
If any problems occur, turn off the power and unplug the
drive, contact your dealer.
Warning about Cleaning
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-F551 to
function properly.

SCSI and DC Power Connector
The SCSI and DC Power Connector is located at the upper
rear of the drive. The drive uses a Molex 53450-5431
combination 50 pin SCSI and 4 pin DC Power male header.
Recommended female connectors:
SCSI connector: 3M type number 7950-6500

* This pin is NOT directly connected to the GND. Do not use this pin as
GND. SMO-F551 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
SMO-F551 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
SMO-F551 features Optional Switch S501 and S502.
These two optional dip switches allow the user to set the
drive configurations.
