Modifying RCU options (Change RCU Option)

Use the RCU Options pane to modify RCU options set when you registered the RCU. When the RCU

Option pane is opened with the Change RCU Option command, all fields are blank. You must fill in the

fields you need to modify; it is not necessary to fill in all fields. Fields left blank keep settings made for the

registering RCU operation.

RCU options apply to all CU images of the current MCU and all RCUs connected to the MCU.
