Option card error 

occurred at Option Port 

CN5-B

Cause

Possible Solution

Option card or hardware is damaged.

• Cycle power to the regenerative unit.
• If the problem continues, replace the control board or the entire regenerative unit. Contact

Same type of option card is currently connected

Cause

Possible Solution

An option card of the same type is already 
installed in option port CN5-A or CN5-B.

Only one of each option card type can only be installed simultaneously. Make sure only one type 
of option card is connected.
