Repair Strategy
The repair strategy for this preprocessor interface is board replacement.
However, the following table lists some mechanical parts that may be
replaced if they are damaged or lost. Contact your nearest Hewlett-Packard
Sales Office for further information on servicing the board.
Exchange assemblies are available when a repairable assembly is returned to
Hewlett-Packard. These assemblies have been set up on the "Exchange
Assembly" program. This allows you to exchange a faulty assembly with one
that has been repaired, calibrated, and performance verified by the factory.
The cost is significantly less than that of a new assembly.
