If a network or computer system manufacturer’s sales representative tells you the use of another manufacture’s memory/GBIC’s/GLC’s in the system manufacturer’s network or computer system will render the system manufacturer’s warranty void, this is a violation of the Magnuson-Moss Act.

Through this ploy, the sales representative attempts to coerce customers into purchasing memory/GBIC/GLC modules from the system manufacturer, usually at grossly over inflated prices. A system manufacturer may resort to this type of warranty threat to spread fear, uncertainty and doubt in the minds of consumers, rather than to compete on the basis of quality and price.

In general, “Tie-In Sales” provisions are not allowed. Such a provision requires the customer to purchase all components directly from the OEM or the warranty is rendered void.
