Connecting Power - ADIC Scalar 100 User Manual

Connecting Power

The ADIC Gateway must be connected to AC Power with a voltage of 100 to 127
or 200 to 240 volts, at a frequency of 50 to 60 Hz. A power switch is located next
to the power connector on the rear panel of the ADIC Gateway.
The ADIC Gateway uses two 250 V, 4 amp Time Lag fuses. They are located in
the fuse holder next to the power switch on the rear panel. If the ADIC Gateway
Main Power LED does not light when the ADIC Gateway power cord is connected
to the power source and is turned on, then check these fuses. Replace only with
F4AL-type fuses.
ADIC Gateway Setup
devices have termination disabled.
• Multiple devices at the same ID: If two or more devices are
configured at the same SCSI ID, only one of those devices will
be seen by the ADIC Gateway, and data transfers to that device
will be unreliable. Check that only one device is set to each ID.
• Target device set to initiator's ID: If a target device is set to the
same ID as the ADIC Gateway (ID 7), the bus will be unstable
and targets will not be identified. Check that no target devices
are set to ID 7, or if one must be set to 7, change the ADIC Gate-
way Initiator ID.
• Bent pins in a SCSI connector: The pins in the SCSI connectors
are somewhat fragile. Inspect each connector to find pins that
were bent when the connector was attached. Replace any cables
with bent pins.
• Improper device type: A DE device on an SE bus or an SE
device on a DE bus will cause the bus to be unusable.
• Improper terminator type: A DE terminator on an SE bus or an
SE terminator on a DE bus will cause the bus to be unusable.
• Inadequate cables: Older cables may not be suitable for running
at Ultra speeds. Be sure all cables are rated for Ultra.
• Mixed cable types: If a SCSI bus has both round cables and flat
ribbon cables, it may suffer problems when running at Ultra
speeds. Use the same cable type consistently for all segments of
the SCSI bus.
• Unshielded cables: An unshielded SCSI cable used external to a
cabinet may cause reliability problems, due to interference from
other electrical devices. Use only shielded cables.
Note: A proper power cable is provided with each ADIC Gateway.
