5.1.1 HEU Main and Auxiliary Configurations
In a configuration with more than one HEU chassis, one HEU (Main) is installed with an HCM module whereas, the additional
HEU units (Auxiliary) are installed with ACM modules, enabling single source management of the ONE™ Wireless Platform
from a single HCM. Figure 5-1 provides an example of the management and RF connections between the Main and Auxiliary
HEU chassis and connected OIUs.
Each OIU is connected to its host HEU through two connections: MGMT (ETH to INTERNAL port) and RF (RIX/OIX ports). For
standalone configurations, up to four OIU chassis can be connected to an HEU.
Note: The maximum configuration is a 4x4 configuration including four HEU connected to four OIU (see section 5.1.2.6 for
RIX-OIX connections; see 0 for management connections).
