In the scenario with battery cabinets, the CIM is installed inside a smart module battery
cabinet and the CIM communications cable connects to a smart ETH gateway. Figure 3-37
shows the CIM and BIM networking in the scenario with battery cabinets.

When a battery system needs to be managed by multiple CIMs, the CIMs can be connected to
northbound devices using straight-through cables (the ECC supports four CIMs in parallel
through the smart ETH gateway) without cascading. Figure 3-38 shows the system
networking.
