Ultra320 SCSI Storage Enclosures
The Module Fault LED is yellow, and illuminates when there is an
I/O module fault.
Joiner Module
Use a Joiner module to create a joined bus, where the enclosure’s
two SCSI busses are joined into one SCSI bus. With a joined bus,
the enclosure has a single bus backplane with up to 12 disk drives
on the bus.
Without a Joiner module inserted, the bus will be split. (See
for installation instructions.)
Note:
If you are not using a Joiner module, you must install an
I/O blank to maintain adequate airflow and cooling inside
the enclosure.
Drive Carrier LEDs
Each drive carrier has three LEDs that are visible from the front of
the Storage Enclosure. See
detailed information about LED functions.
Cables and Termination
The Adaptec Ultra320 Storage Enclosure is self-terminated for
single- and dual-bus configurations and does not need external
termination.
You can use cables up to 5 meters (16.4 feet) long to connect the
enclosure to hosts.
To connect the enclosure to a host, use interconnect cables with
these connectors:
■
To connect to the enclosure
—68-pin VHDCI connector.
■
To connect to the host
—Either a high-density 68-pin connector
or a 68-pin VHDCI connector (depending on the type of host
bus adapter.)
