Note: There are four versions of the SX4030 expansion module: SX4030W/1, SX4030UW/1, SX4030W/2 and SX4030UW/2. The first two modules have a single SCSI connector (J5). This adds one bus, supporting fifteen additional devices. Expansion modules SX4030W/2 and SX4030UW/2 have two SCSI connectors (J5 and J6), supporting an 30 additional devices.

Notes: Although not shown above, 1MB, 4MB and 16MB SIMMs can be combined and DPT ECC SIMMs can replace parity SIMMs of 4MB or 16MB. Single sided SIMMs are preferred, but low-profile double sided 2MB and 8MB increments are supported.
