3.2.2 Height-Restricted Scenarios

This section describes the height-restricted scenarios for installing the DBS3900 on an ICR.
Height-Restricted Scenarios (-48 V DC)
This section describes the height-restricted scenarios with external -48 V DC power supply. In
these scenarios, DC RRUs can be installed together with an IMB03 on an IFS06 or independently
on an IFS06.
DC RRUs and IMB03 Installed Together (IFS06+IMB03+DC RRUs)
In this scenario, a single IFS06 supports a maximum of six DC RRUs, and a single site supports
a maximum of 12 DC RRUs. When only three DC RRUs need to be installed, they are installed
at the lower layer.
