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.
Fault Mode Selection
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 plug.
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 2 posts.
3. Carefully position the plug on 2 of the 3 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
backplane connector:
•
Between 2 and 4
•
Between 12 and 14
You can change the position of these keys if system redesign and
rewiring makes insertion of a different module necessary.
