1. Does the Lumina charger support Gigabit Ethernet (1000 Mbps)?

No, the Lumina charger supports Ethernet speeds up to 100 Mbps (Fast Ethernet). It does not support Gigabit Ethernet. Attempting to connect it to a network that strictly enforces 1 Gbps connections may result in a failure to establish a link.

2. How does the Auto-Negotiation function work in Lumina?

The Auto-Negotiation feature allows the Lumina charger to automatically determine the optimal link speed and duplex mode (10/100 Mbps, full/half duplex) based on the capabilities of the connected network device. This eliminates the need for manual configuration and ensures compatibility in most network environments.

3. What should I do if my switch or router only supports 1 Gbps?

If your network infrastructure does not support 10/100 Mbps, you have several options:

• Use a switch or media converter that supports Auto-Negotiation and 10/100 Mbps fallback.

• Check if the switch can be manually configured to allow connections at lower speeds.

• Insert a 10/100 Mbps unmanaged switch between the Lumina charger and the gigabit-only network.

4. Is 100 Mbps enough for EV charger communication?

Yes. For the Lumina charger’s typical communication needs — such as data logging, remote status monitoring, firmware updates, and system integration — 100 Mbps is more than sufficient. These operations require minimal bandwidth.

5. Can I manually configure the Ethernet speed on Lumina?

No. Lumina relies on Auto-Negotiation to establish the best connection. Manual Ethernet speed configuration is not supported on the device side.

6. Will using a 100 Mbps connection limit the performance of the charger?

No. Network speed does not affect the actual charging performance of the Lumina device. The Ethernet connection is used strictly for data communication, which requires significantly less bandwidth than the power delivery system.

7. Is Lumina compatible with industrial network environments?

Yes. Lumina is fully compatible with most industrial networks, which often operate at 10/100 Mbps. Its robust design and auto-negotiation support make it ideal for deployment in demanding or legacy network infrastructures.
