| SX4000 EXPANSION MODULE CONNECTIONS |
|------------------------------------------------------------|
| Function | Location |
|----------------------------------------------+-------------|
| 50-pin SCSI bus 1 connector - internal | P1 |
|----------------------------------------------+-------------|
| 50-pin SCSI bus 2 connector - internal (see | P2 |
| note) | |
|----------------------------------------------+-------------|
| Proprietary connector from SX4000 module to | P15B |
| adapter | |
|----------------------------------------------+-------------|
| Proprietary connector from SX4000 module to | P16B |
| adapter | |
|------------------------------------------------------------|
| 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. |
