Overview
HF-IES-2528M series of Ethernet switches are 28-port industrial Ethernet switches, supporting HF-RING redundancy technology, it can be configured flexibly according to your actual needs(e.g. 4 Gigabit Combo + 24 10/100/1000M Base-TX etc.), all ports support auto negotiation, 10/100/1000M, full/half duplex, auto MDI/MDIX, flow control; Offering advanced management functions by  Web management such as HF-RING, VLAN, Qos, Trunking, IGMP Snooping, Rate Control, Port Mirroring, Static MAC address transmitting, SNMP, diagnostic tools, failure warning etc. It’s plug and play, no needing field regulation. HF-IES-2528M switches are designed in wide operating temperature from -40ºC to 85ºC, with performance of dust/salt fog proof, make it completely suitable for harsh environments.
