American Electrical's Power over Ethernet (PoE) 3, 4, or 8-port 802.3af/at unmanaged, hardened, industrial-grade switches are designed to reliably connect PoE devices in harsh environments. The switches feature three, four, or eight 802.3af/at Gigabit PoE ports and one Gigabit LAN uplink or SPF uplink which allows it to handle cutting-edge, high-power, and high-bandwidth devices. The switches were designed with durability in mind. An IP67-rated metal case, fanless design, 6 kV surge-protected power input, and a -40°C to +65°C operating temperature range mean that these switches are extremely resistant to hardware failure and well-suited to even the most demanding operating conditions. The switches’ small form factor and unmanaged plug-and-play interface mean that they can be quickly and easily added to any network.
