ATTENTION: Observe the following precautions
when inserting or removing keys:
•
insert or remove keys with your fingers
•
make sure that key placement is correct
Incorrect keying or the use of a tool can result in
damage to the backplane connector and possible
system faults.
Position the keying bands in the backplane connectors to
correspond to the key slots on the CFM module.
keying bands

Place the keying bands:
between 2 and 4
between 6 and 8
The CFM module is slotted in two places on the rear edge of
the circuit board. These slots are intended to mate with the
plastic keying bands supplied with the I/O chassis.
You can change the position of these bands if subsequent system design
and rewiring makes insertion of a different type of module necessary.
