EKI-2528PAI is a rugged, eight-port, and unmanaged Power-over-Ethernet (PoE) Ethernet switch. It features eight 10/100Base-TX Ethernet ports, four of which can supply power to PoE-compliant devices. Unlike most PoE switches, EKI-2528PAI does not require a separate 48 VDC power source. It's ruggedized with redundant power inputs, 4000 VDC Ethernet ESD protection, power line surge (EFT) protection, and is certified by CUL (UL/CSA), UL508, CE, FCC and RoHS/WEE.
