DISTRIBUTED PROCESSING TECHNOLOGY PM3222, PM3222W Data bus: 32-bit EISA Size: Three-fourths length, full-height card Hard drive supported: Up to seven SCSI-2, SCSI-3 or Fast SCSI devices(PM3222) Up to fifteen Wide SCSI devices (PM3222W) Up to 45 Wide SCSI devices with expansion board upgrades Floppy drives None supported: [Image] ADAPTER CONNECTIONS Function Location 3-pin connector - remote alarm P4 4-pin connector - drive active LED P6 50-pin SCSI bus 0 connector - internal P10 Proprietary connector to SX4000 expansion P15A module Proprietary connector to SX4000 expansion P16A module 50/68-pin SCSI bus 0 connector - external J11 Note: 50-pin external ports are on the PM3222 models. 68-pin ports are on the PM3222W. ADAPTER CONNECTIONS (CONTINUED) Function Location LED - adapter busy LED1/1 LED - computer bus transfer to adapter LED1/2 LED - computer bus transfer from adapter LED1/3 LED - cache hit LED1/4 LED - disk read/ahead active LED1/5 LED - disk read LED1/6 LED - disk write LED1/7 LED - adapter reset LED1/8 LED - interrupt to computer pending LED1/9 LED - DRQ to computer asserted LED1/10 ECC enabled LED - green LED2 Parity error LED - red LED3 ECC error LED - red LED4 Note: The configuration of the 10-segment LED1 is unidentified. 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.
