DISTRIBUTED PROCESSING TECHNOLOGY PM3224, PM3224W, PM3224-MAC, PM3224W-MAC Data bus: 32-bit PCI Size: Three-quarter length, full-height card Hard drive supported: Up to seven SCSI-2, SCSI-3 or Fast SCSI devices (PM3224 and PM3224-MAC) Up to fifteen Wide SCSI devices (PM3224W and PM3224W-MAC) Up to 45 Wide SCSI devices with expansion board upgrades Floppy drives supported: None [Image] ADAPTER CONNECTIONS Function Location 3-pin connector - remote alarm P4 4-pin connector - drive active LED P6 Proprietary connector to SX4000 expansion P15A module Proprietary connector to SX4000 expansion P16A module 50/68-pin SCSI bus 0 connector - internal J10 50/68-pin SCSI bus 0 connector - external J11 ECC error LED - red LED2 Parity error LED - red LED3 ECC enabled LED - green LED4 LED - adapter busy DS/1 LED - computer bus transfer to adapter DS/2 LED - computer bus transfer from adapter DS/3 LED - cache hit DS/4 LED - disk read/ahead active DS/5 LED - disk read DS/6 LED - disk write DS/7 LED - adapter reset DS/8 LED - interrupt to computer pending DS/9 LED - DRQ to computer asserted DS/10 Note: 50-pin external ports are on the PM3224 models. 68-pin ports are on the PM3224/W. 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 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.

Single sided SIMMs are preferred, but low-profile double sided 2MB and 8MB increments are supported.
