We are not able to add more than one rack and BMXNOM0200 module with BMXP342020 in the configuration.

How can we help you today?

With BMXP342020 CPU version 1.0 it will supports only one rack in the topology and also NOM module also not supported with this version.
For BMX P34 20X0 with OS version 2.0 or higher supports 4 Racks maximum.
To use NOM module with BMX P34 20X0 cpu then maintain the minimum version of CPU OS to 2.10.
