DEC 4000 AXP

This document serves as a comprehensive guide for Digital Equipment Corporation's DEC 4000 AXP systems, providing reference, configuration, and maintenance information for supported options. It is intended for service representatives and qualified self-maintenance customers.

The guide is organized alphabetically by option, detailing:

• System-Bus Modules: Includes CPU modules (B2001, B2012) based on the DECchip 21064 Alpha AXP microprocessor with varying cache sizes (1MB to 4MB) and support for symmetric multiprocessing (SMP); Memory modules (B2002) offering 64MB-128MB capacity; and a 2-MB NVRAM module (B2013) acting as an NFS server accelerator/write cache.
• I/O Modules (B2101): Features a complete I/O subsystem with Futurebus+, Ethernet, and multiple SCSI/DSSI channels (standard or Fast SCSI).
• Futurebus+ Modules: Covers the B2006 FDDI Futurebus+ Controller, an adapter with single (SAS) or dual (DAS) attachment station capabilities for fiber optic connections.
• Storage Options:
  • Fixed Disks (RF-Series, RZ-Series): Ranges from 852MB to 42.0GB in 3 1/2-inch and 5 1/4-inch form factors, with DSSI, SCSI, or Fast SCSI interfaces.
  • Optical Disc Drives (RRD42): A 600MB half-height optical compact disc (ROM) drive with audio features and a SCSI interface.
  • Tape Drives (TKZ09, TLZ06, TLZ6L, TSZ07, TZ30, TZ8x, TZ8x7): Includes various cassette tape drives (DAT, CompacTape III) and a reel-to-reel magnetic tape drive (TSZ07), offering capacities from 95MB to 42.0GB, with SCSI interfaces, and auto loader options (TLZ6L, TZ8x7).

Each option section includes an overview, part numbers, indicator light summaries, illustrations, configuration, and handling information. The document also provides a quick reference table of all supported options and storage tray information, including details on blank bezels, media selection, and termination. A critical caution about static electricity is highlighted for internal work.
