 Even though the Quantum CPU can support a maximum of 6 Network option modules, it can only have a maximum of four 140NOC78000 modules.
From User Manual page 18,  A maximum of 6 communication modules can be configured on the local rack. Therefore, you can configure only four 140 NOC 780 00 modules. (For the remaining 2 communication modules, you can install a 140 NO• 771 •• or 140 NOM 2•2 00 module.) If you configure a 140NOC78 100 control head module on the local rack to manage a control network, you can only configure four 140NOC78000 modules on the local rack.
