SCSI #1 Configuration
Note: Correct SCSI bus selection: The Base-520(G) provides 1 SCSI
bus, SCSI #1. A further SCSI controller, SCSI #2, is available with
the I/O-52x(G). Its termination is described in the I/O-52x(G)
installation section.
SCSI #1
termination
The Base-520(G)’s SCSI #1 bus is accessible via the Base-520(G)’s
front-panel SCSI #1 connector (8-bit SCSI) and via the Base-520(G)’s J5
connector (Wide SCSI). Therefore, the Base-520(G) holds 2 distinct
SCSI bus terminations to enable correct termination of the SCSI #1 bus.
Associated to the 2 terminations there are 2 switches – SW5-1 and
SW5-2 – which allow easy selection of a valid SCSI #1 bus configura-
tion.
There are 4 valid Base-520(G) switch settings corresponding to valid
SCSI #1 bus configurations. The following factors differentiate the valid
SCSI #1 bus configurations:
•
the Base-520(G)’s location within the SCSI #1 bus: Is the
Base-520(G) located at an endpoint of the SCSI #1 bus?
•
the connector(s) being used from the SCSI #1 bus:
– Is a SCSI cable plugged into the Base-520(G)’s front-panel SCSI
connector?
– Is the Base-520(G)’s CompactPCI J5 connector used by the
SCSI #1 bus?
– Are both Base-520(G) connectors used by the SCSI #1 bus?
•
the SCSI device type being connected to the SCSI #1 bus: Is a Wide-
SCSI device connected to the J5 connector?
Each of the following configuration descriptions starts with identifying
the SCSI #1 bus configuration being covered and ends with defining the
correct switch setting corresponding to the configuration under consider-
ation.
