Multia MultiClient Desktop Service Information

This document, "Multia MultiClient Desktop Service Information (EK-MULTS-IN.C01)", published in October 1995, serves as a comprehensive guide for Digital service personnel and qualified self-maintenance customers on how to troubleshoot and service the Multia MultiClient Desktop, covering both Alpha- and Intel-based models.

The guide is structured into several key sections:

• System Description: Provides a detailed overview of the Multia MultiClient Desktop, including its hardware features (e.g., CPU types, memory, graphics, storage, ports for Alpha-based VX40/41/42 and Intel-based VX51 models), software features (preinstalled Windows NT Workstation and Multia Base Software, administrative tools, communication protocols), physical layout (front and rear views with labeled connectors), technical specifications (system board, memory, power supply, mechanical, environment), and configuration options (system box layout, memory SIMM configurations, available hardware options).

• Troubleshooting: Offers extensive guidance for diagnosing and resolving issues for both Alpha-based and Intel-based models. It covers a wide range of problems, including:

  • Power system and initialization/POST errors (e.g., SROM LED codes for Alpha models, beep codes for Intel).
  • Boot problems (e.g., identifying boot devices, environment variables).
  • Component-specific issues related to memory, network interfaces, disk drives (floppy, IDE, SCSI), monitors, and audio.
  • Instructions on accessing Windows NT Event Logs for further diagnostics.

• Console Commands & Setup Utilities:

  • For Alpha-based models, it details the ARC Console commands (for Windows NT system management, including boot menu options, setup, and environment variables) and SRM Console commands (Multia diagnostics console, with specific commands like Deposit, Examine, HD, and Show). It also explains how to switch between these consoles.
  • For Intel-based models, it covers the BIOS Setup Utility, outlining how to run it, navigate its menus, and configure various system settings such as IDE hard disk options, memory cache, boot sequence, security, and power options. Procedures for resetting boot configurations are provided for both Alpha and Intel systems.

• Hardware Service (FRU Replacement): Describes procedures for removing and replacing Field Replaceable Units (FRUs). This section covers memory modules (SIMMs), cache memory, processor upgrades (Alpha and Intel), PCI options, power supply, various disk drives, backplanes, system boards, batteries, speakers, and cables. A static electricity caution is emphasized.

• Software Restoration: Explains how to restore Multia software to its initial factory state using the Multia CD-ROM and RMF diskette (for Intel models), including necessary MOP or BOOTP and TFTP server setup for remote maintenance.

• Reference Information: Includes comprehensive part numbers for recommended spares, FRUs, various system box configurations, memory, disk drives, keyboards, monitors, and cables. Detailed pinout diagrams are provided for all major ports (parallel, serial, SCSI, floppy, keyboard, mouse, network, power, video) and system board jumper settings for both Alpha- and Intel-based models.
