The ControlNet adapter module requires a backplane current of 1.0A
at 5V dc. Remember to add this amount to other current
requirements for your I/O chassis.
The ControlNet adapter module must be installed in the leftmost slot
of the I/O chassis.
The I/O chassis backplane connectors are keyed to accept only one
type of module. This prevents accidental insertion of other modules
in the wrong module slot.
Position the keying bands (Figure 2.1) in the backplane connectors to
correspond to the key slots on the module. This prevents you from
inserting the wrong module in this slot. For the ControlNet adapter
module, position the keying bands:
•
between 54 and 56 on the upper connector, and
•
between 16 and 18 on the lower connector
!
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.
