Install the ControlNet Module
To install the module, perform this procedure.
1. Align the circuit board with top and bottom guides in the
chassis.
2. Slide the module into the chassis.
WARNING
When you insert or remove the module while backplane power is on, an
electrical arc can occur. This could cause an explosion in hazardous location
installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
Repeated electrical arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contacts may create electrical
resistance that can affect module operation.
