Frequently Asked Questions

Does the ER-X-SFP support 802.3af/at PoE?

No — the PoE passthrough on ETH4 is passive 24V only, not 802.3af or 802.3at. It is compatible with Ubiquiti airMAX devices and other 24V passive PoE equipment.

What is the difference between ER-X and ER-X-SFP?

The ER-X-SFP adds a 1GbE SFP port compared to the standard ER-X, enabling fiber WAN or additional uplink connectivity.

Does it support hardware-accelerated routing?

Yes — the ER-X-SFP uses Cavium hardware offloading to achieve up to 1 Gbps routing throughput with offload enabled in EdgeOS.
