NOTE: The building's Internet router must have enough ports available, and the network <br />providing the Internet connectivity must allow the Ethernet gateway to be connected to it, <br />including an appropriately set up firewall and IP address. In some cases, an Ethernet switch <br />(customer supplied) rated for the operating environment and with adequate number of LAN <br />ports is required. <br />5.2.3. Master Router / Auxiliary Gateways <br />If the cellular signal is low or inexistent and there is no Internet router connectivity in <br />underground structures, a master router combined with one or more auxiliary gateways <br />may have to be installed. <br />The master router should be placed in an area where a cellular signal is available and will <br />transfer the data to the CPO backend. Its communication with the auxiliary gateways is <br />done through an Ethernet cable. The communication between the charging stations and <br />the auxiliary gateways is still done through Zigbee. <br />CPO backend <br />Cellular Signal <br />Master Router <br />Charging Ethernet Cable <br />station(s) RJ45, CATS, orCAT6 <br />•�))��_; Auxiliary <br />Zigbee Gateway <br />OPTION 3 <br />Master router - Auxiliary <br />Gateway <br />
