ATTENTION:
Users of Series 300 Computer Systems
Please read this notice berore installing card.
The HP 98640A has one application which may pose serious usage problems:
In Series 300 machines, the right angle posts which connect the ADC card to its Wire Termination
Assembly can short out on the RFI suppression shield of the processor or other card if the cards are in
adjacent slots. Since the HP 98640A must be installed in the lower of paired slots, this occurance is likely.
There are two possible solutions.
The recommended solution is to apply an insulating material (such as electricial tape) to the upper surface
of the RFI shield on the processor or other ca rd.
The second, while more difficult. is equally effective: Always place the ADC card in a slot where the
contacts are cl4early not touching any conductor. This is not always possible due to the installation
constraint mentioned above.
