Both microprocessor module sockets must be filled regardless of how many microprocessors are installed; you must use a bus termination module in the second socket if you have only one microprocessor installed. Note that both sockets on the primary module should be populated before populating the sockets on the secondary module. Table
Similarly, both of the microprocessor module connectors on the system board must be populated. For example, if you are using only one or two microprocessors on one microprocessor module (thus populating the primary connector), the second connector on the system board must also be populated with either another micro- processor module or a terminator card.
