When deploying multiple FortiAnalyzer units on a network, what must be configured differently on each unit?

When deploying multiple FortiAnalyzer units in a network, each unit must have a distinct management IP address. This unique identification is essential for network communication, enabling administrators to connect to each FortiAnalyzer without conflicts that would arise from duplicated IP addresses. Having different management IPs ensures that each unit can be accessed individually for management and reporting tasks without any overlap or confusion.

While it's important for devices to have secure access, sharing the same default admin password across multiple units isn't advisable, but it doesn't necessitate configuration differentiation for functionality. Similarly, the operating system version should ideally be the same across units for compatibility and functionality, meaning it doesn't need to vary between them. Network topology settings, on the other hand, relate to the physical layout and connections of the network itself rather than individual unit configuration. Therefore, ensuring that each FortiAnalyzer has its own management IP is the correct and necessary configuration step in this scenario.
