CHAPTER 3: Installation
3. Installation
3.1 AC Line Voltage
The SCSI Fiber Optic Extender can be externally connected to any AC input
voltage between 100 and 240 volts. In the USA, your Extender will be shipped with
a 110-volt power cord. Black Box offers offers a complete source of replacement
power cords for most countries. Call Technical Support at 724-746-5500 for details.
3.2 Positioning the Extender
Place the Extender in a convenient location near the host computer and/or
peripherals. Make sure that the ventilation slots on the sides of the unit have
adequate airflow. Do not place the Extender on any devices that generate excessive
heat.
3.3 Cable Recommendations
High-quality shielded SCSI cables will provide a connection with the greatest noise
immunity and distance from the Extender to your peripherals. But in any case, no
cables connected to the Extender may exceed 6 meters (19.7 ft.) for single-ended
units and 25 meters (82 ft.) for LVD and differential units.
NOTE
Peripherals operating at Ultra SCSI data rates require shorter cable
lengths for proper operation. The total cable length for a single-ended
Ultra SCSI bus should be no longer than 1 meter (3.3 ft.) and differential
cables 12 meters (39.4 ft.).
3.4 Connecting the Extender to the SCSI Bus
NOTE
Before you connect the Extender, switch off power to all computers and
peripherals attached to the SCSI bus.
You may install the Extender at any point on the SCSI bus. The Extender has a
SCSI connector with screw lock for secure connections.
NOTE
The SCSI Fiber Optic Extender can be operated with another differential
SCSI Fiber Optic Extender to convert from one bus type to the other.
