Use the slot assignment charts for systems with the 501-1138
or 501-1217 SCSI Assembly if there is no SCSI Host Adapter
installed in a Sun-3/180, Sun-3/280, or Sun-4/280.
Sun 3x2 Adapter, 501-1269, Option 160A, is connected to J2
Rows A and C. There is no external connector.
Sun 3x2 Adapter, 501-1191, Option 160B, is not connected to
J2 Rows A and C. There is no external connector.
Sun 3x2 Adapter, 501-1220, has no connection to J2 Rows A
and C and has an external 50-pin connector.
Sun 3x2 Adapter, 501-1666, is connected to J2 Rows A and C
and has an external 50-pin connector. This adapter connects
the Sun 4300 CPU to the internal SCSI subsystem of the Sun-4/360.
Sun-2 SCSI Host Adapter, 501-1167, has P2 bus connections
and an external cable assembly. Do not substitute a 501-1236
Sun-3 SCSI for a 501-1045 Sun-2 SCSI in this adapter assembly.
Sun-3 SCSI Host Adapter, 501-1217, does not function with the
SCSI subsystem in the Sun-3/160, Sun-3/260, or Sun-4/260.
The SCSI subsystem interfaces through J2, Rows A and B, of
the VMEbus connector. These signals are not connected on the
501-1217 assembly.
