speeds. Any Cat5e-rated or higher Ethernet cable of suitable length may be used to connect to this
RJ45 jack.

Connecting both ports 7 & 8 at the same time will create a loop and will cause
interference with the operation of the external network.
No connection should be made to the IPMI port, unless directed by Nuvation Energy.
Refer to the network port connection map
Below is a diagram of the installation of the Multi-Stack Controller with the Stack Switchgear. In case
the external controller does not support 1 Gbps (shown below), and only supports 10/100 Mbps, an
Ethernet switch must be added.

4.2.4. Step 3: Verify Grounding

The Multi-Stack Controller must be mounted to an Earth bonded metal structure to maintain a reliable
ground. This references all components internal to the Multi-Stack Controller to earth ground, as the
negative input of the DC power connector is also connected to the chassis. Earth ground is also
passed along to shielded connectors (e.g. Ethernet and USB).

The external supply has its negative input connected to earth ground through the
Multi-Stack Controller module's chassis.
These instructions assume that attention is paid to proper grounding instructions and best practices
for any and all Stack Switchgear units and Cell Interface modules. Please refer to the stack-level
Product Manual for this information.
It is also assumed that similar measures are taken for other components of the battery energy
storage system such as the batteries and the power conversion system.
