Memory Option Installation Card

This document provides a quick reference guide for installing 3X-MS310-XX memory options (DIMMs) in Compaq AlphaServer DS10 or AlphaStation XP900 systems.

Key Information & Steps:

1. Purpose: To guide users through the process of installing or replacing memory modules.
2. Safety Warnings:
   • Access is restricted to technically trained and experienced personnel.
   • CPU and memory modules can be hot; wait 2 minutes after power-off before touching.
   • Always wear an antistatic wrist strap.
3. Installation Overview:
   • Shut down the operating system and power down the system.
   • Open the system cabinet.
   • Access memory slots (requires removing the floppy disk drive).
   • Install the memory option (two DIMMs per option).
   • Restart the system.
   • Verify the installation.
4. Important Configuration Rules:
   • A memory option consists of two DIMMs.
   • DIMMs within the same memory bank must be of the same capacity (though different banks can have mixed capacities).
   • It is recommended that DIMMs in a bank be from the same manufacturer.
   • At least one memory bank (Bank 0 or 1) must be filled.
5. Installation Process Highlights:
   • Unplug the power cord before opening the cabinet.
   • Unlock and remove the system covers.
   • Remove the floppy disk drive by pulling its cylinder pins inward and pulling the unit back/up.
   • Open the memory connector levers by pushing them down and outward.
   • Align and press the DIMM into the connector until the levers close.
6. Verification:
   • Tru64 UNIX and OpenVMS: At the SRM console prompt, issue the show memory command.
   • Windows NT: During boot, press F2 to enter AlphaBIOS, then navigate to "Display System" -> "Memory Configuration."
