changed after saving or non-volatile memory has been corrupted.
sc_fault_fw_mismatch
▪
Fault indicating that the stack controller and power interface subsystem firmware versions are
different. Perform an upgrade to the desired battery management system firmware version.
sc_fault_clocks
▪
Fault indicating that the stack controller and power interface subsystem clocks are ticking at
different rates. This may indicate an overloaded system or malfunction in the hardware or
software. Also if one of the processors resets, this fault can trip since its clock also resets.
sc_fault_linkbus_power
▪
Fault indicating that there was an incorrect power mode in sc_linkbus.power_mode

10.2. Lost/Forgotten IP Address

If a Nuvation Energy BMS has been configured with a static IP address and it has been forgotten,
follow the steps below to recover it.
Depending on the network interface used on the PC, this process may not work due

to differing security and IP configurations. If the only IP discovered is the IP of the
PC, the network interface is not suitable and another one will need to be used. This
issue is most common with USB to Ethernet dongles.

10.2.1. Wireshark (Windows/Linux)

1. Download/install Wireshark on a PC (https://www.wireshark.org/)
2. Connect the PC directly to the Ethernet port on the Low-Voltage BMS
3. Start a Wireshark capture on the network interface connected to the Low-Voltage BMS
4. In the 'filter' field, enter in arp.isgratuitous and press enter
5. Either reboot the Low-Voltage BMS, or unplug/plug the Ethernet cable
6. The device should send a 'Gratuitous ARP' on the Ethernet network. In Wireshark the 'Info' field
looks like: Gratuitous ARP for <IP> (Request) where the <IP> is the address for the Low-Voltage
BMS
7. Once that is complete, update the PC network settings to match the Low-Voltage BMS and
connect the Operator Interface.

10.2.2. Netdiscover (Linux only)

1. Install netdiscover on a PC (on Debian based systems use: sudo apt install netdiscover)
2. Connect the PC directly to the Ethernet port on the Low-Voltage BMS
3. Run sudo netdiscover -i <interface> -p where <interface> is the network interface connected to the
