Dual SCSI Module (PMAZB-AA)

This owner's guide provides general information for the Dual SCSI TURBOchannel module (PMAZB-AA), a single-ended TURBOchannel-to-SCSI controller offering two additional 8-bit, 5-MB/sec SCSI ports and occupying one system slot. It is designed for AXP-based systems, compatible with OpenVMS AXP (V1.5 and later) and DEC OSF/1 AXP operating systems, but not supported on MIPS-based systems or in the TURBOchannel Extender.

The guide covers:

• Module Description: Details its function and specifications.
• Jumper Settings: Explains the correct placement of terminator jumpers and the flash memory write jumper (which should generally be removed unless updating ROM code or using the setid utility).
• Installation: Emphasizes wearing an antistatic wrist strap, proper grounding, and potential need to trim rear panel plastic for cable connection.
• Confirming Installation: Describes how to verify installation through system configuration display and notes on startup testing.
• Running Self-Tests: Provides command formats and details various diagnostic tests (asic, reg, int, trans) and test scripts (pst-q, pst-t, pst-m) to diagnose issues in console mode.
• The setid Utility: Explains how to set SCSI IDs (addresses) for the two ports, noting default IDs are 7 and providing command formats for current settings and modifications.
• Boot Command: Briefly outlines how to use the boot command to specify a boot device.
• SCSI Port Designations: An appendix lists pinout details for the SCSI ports.
