SX4000 EXPANSION MODULE CONNECTIONS

Function

Location

50-pin SCSI bus 1 connector - internal

P1

50-pin SCSI bus 2 connector - internal (see note)

P2

Proprietary connector from SX4000 module to adapter

P15B

Proprietary connector from SX4000 module to adapter

P16B

Note: There are four versions of the SX4000 expansion module: SX4000/1, SX4000W/1, SX4000/2

and SX4000W/2. The first two modules have a single SCSI connector (P1). This adds one bus,

supporting seven additional devices on the PM3222 and an additional fifteen on the PM3222W.

Expansion modules SX4000/2 and SX4000W/2 each have two SCSI connectors (P1 and P2).

This adds two buses, permitting the PM3222 to support an additional 14 devices, and the

PM3222W to support an additional 30.

Proprietary connectors P15B and P16B are on the reverse side of the expansion module.

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 2M and 8MB increments are supported.
