When not in use, keep the module in a static-shielded bag.
In this section we tell you how to set the fault mode selection plug,
key your I/O chassis, install your module and make your wiring
connections.
Setting the Fault Mode
You may select one of two input-failure configurations (last state or
reset) by positioning a configuration plug on the top edge of the
printed circuit board. This configuration plug is independent of the
last state switch on the I/O chassis backplane during a module fault.
During a chassis fault, the I/O chassis backplane last state switch
setting overrides the module fault mode selection.
To set the fault mode selection, proceed as follows:
1. Locate the fault mode selection plug at the top edge of the
module circuit board.

2. Using your finger, slide the plug off the two posts.
3. Carefully position the plug on two of the three posts that
correspond to your requirement.
Keying Your I/O Chassis
Use the plastic keying bands, shipped with each I/O chassis, to key
the I/O slots to accept only this type of module.
The module circuit board is slotted in two places on the rear edge.
The position of the keying bands on the backplane connector must
correspond to these slots to allow insertion of the module. You can
key any connector in an I/O chassis to receive this module except for
the left-most connector reserved for adapter or processor modules.
Place keying bands between the following numbers labeled on the
upper backplane connector:
•
Between 10 and 12
•
Between 18 and 20
