Smp Upgrade

This Field Change Order (FCO) details the requirements and procedures for upgrading a DEC 4000 system to a multiprocessor (SMP) configuration. It specifies that existing memory modules (B2002-CA/DA) must be at least revision C01; older versions will cause system crashes due to parity errors. The document covers applicability, hardware checks (using 'show fru'), safety precautions regarding ESD and power, installation steps, and system verification using memory exercisers and diagnostics. It also includes charging and reporting information for service engineers.
