vi. Unplug the battery harness from the PCB to manually
power cycle it. Replug it into the PCB to reboot the node - if
there is a yellow XT-90 connector on the battery harness, you
may unplug and replug that instead.
Issue 3: When the node is turned on, it cannot get past boot
(yellow) mode.
i. Ensure that the yellow LED indicators turn on during
booting. The node should be turned on through the mobile
app, with the switch staying in the “on” position for longer
than 10 seconds.
ii. If the node shows yellow LED indicators but then continually
restarts, verify that it has at least 20% of battery remaining.
Nodes in a low-battery state will not turn on until roughly
20% to protect the cells.
iii. The batteries may be in a failure state due to its protection
circuitry. Charge the node for at least 1 hour to attempt to
override this state; ideally, use the solar panel to charge the
node, but a USB-C charger (60W or higher) can also be used
so long that the node is verified to be charging.
iv. The Bluetooth firmware may need to be updated - for
instruction, please visit section 11.b - Mobile App Diagnostics .

Charging Issues
Issue 4: Charging the node via USB-C power delivery is not
working. USB-C charging is not supported on active or passive
Power over Ethernet injector (PoE PSE) configurations.
i. Ensure that the node can be turned on with at least 20%
battery and can enter normal states (its LED indicators are
lighting up).
ii. If the USB-C charging cable is being directly connected to
the node, make sure that it is fully inserted. Attempt to
