Configuration of a Redundancy Communications Module

Asdescribed previously, one Redundancy Communications Module (the Local unit) must be configured in rack 0 (can be in slots 2 to 9). There must not be an empty slot between the CPU 780 module and the RCM module. If there is an empty slot, the configuration will be invalid. The following example screens show an RCM configured in slot 2 in rack 0. While in the I/O Configuration rack screen, cursor to slot 2 (currently empty) as shown below.

Select the bem softkey (f3) from the I/O Configuration rack screen, the following screen will be displayed:
