CONFIGURATION AND INSTALLATION
Page 2-2
To better explain how to configure your MMAC, refer to the following
examples. Figure 2-1 illustrates how the combined load of two
FDCMIMs exceeds the available power of an MMAC-3FNB.

Figure 2-2 represents an MMAC-5FNB equipped with dual power
supplies and three FDCMIMs. The MMAC has enough power to
support the configuration. However, the combined load of the modules
exceeds the output of a single power supply. This means that the hub
does not have redundant power (the ability of one power supply to
assume the entire load if one supply fails).

Figure 2-3 represents an MMAC-M8FNB equipped with a full
complement of power supplies and three FDCMIMs. The MMAC
power supplies can produce up to 80 amps of power, providing more
than double the power necessary for operation. This configuration
provides redundant power to the hub.
