In this section we tell you how to set the module fault mode, key

your I/O chassis, install your module and make your wiring

connections.

You may select one of two output-failure configurations (last state or

reset) by positioning a selection jumper on the bottom edge of the

printed circuit board. The setting of this selection jumper determines

how the module presents its outputs in the event of an internal

module fault. With processor-to-I/O module communication faults,

the position of the last state switch on the I/O chassis backplane

controls the outputs.

To set the fault mode selection, proceed as follows:

13.Locate the fault mode selection jumper at the bottom edge of the

module circuit board.

14.Using your finger, slide the jumper off the 2 posts.

15.Carefully position the jumper on 2 of the 3 posts that correspond

to your requirement.
