FAQ
Q: Can CP461-51-S2 modules be used in a mixed redundant pair with CP471?
A: No, redundant pairs must consist of two identical modules, either CP461 or CP471.
Q: How many processor modules can be installed in a single FCU?
A: Up to two modules per dual-redundant pair, with a maximum of eight modules depending on system configuration.
Q: Are all communication modules compatible with dual-redundant operation?
A: ESB bus couplers, N-ESB couplers, and Optical ESB modules require dual-redundant configuration. Other communication modules can operate in single or dual-redundant mode.
