Attention

The IF8IU module does not receive power from the backplane. +24V

dc power must be applied to your module before operation. If power

is not applied, the module position will appear to the adapter as an

empty slot in your chassis. If the adapter does not recognize your

module after installation is completed, cycle power to the adapter.

Attention

Use supply wire for 10˚C above surrounding ambient.
