Switch Juniper EX4100-F-12P là thiết bị chuyển mạch nhỏ gọn, không quạt cung cấp 12 x 1GbE cổng truy cập Ethernet, có khả năng cấp nguồn PoE + lên đến 30 W cho mỗi cổng với tổng số ngân sách nguồn PoE 180 W khi sử dụng nguồn DC. EX4100-F-12P cũng có thể được cấp nguồn từ thiết bị bên ngoài (PSE) kết nối thông qua cổng Uplink PD, có thêm 90 W ngân sách PoE bổ sung nếu cổng Uplink PD thứ hai được kết nối với thiết bị PSE. Khi kết hợp cả nguồn DC và hai cổng Uplink PD được kết nối với với PSE bên ngoài, tổng ngân sách nguồn PoE được hỗ trợ lên đến 300 W.
