(2) Insert the other end of the same cable into the lower RJ45
connection socket on the energy storage module above.
(3) Repeat the process until all the energy storage modules are
connected with each other via RJ45 cables.
(4) Insert the RJ45 terminating resistor into the lowest free
RJ45 connection socket on the bottom energy storage
module.
