Key features

Advanced L2 functions Stacking support Multicast support (IGMP Snooping, MVR) Advanced security features (L2-L4 ACL, IP Source Guard, Dynamic ARP Inspection, etc.) Battery backup power supply Surge protection MES access switches connect end users to large enterprise networks, small and medium-sized business networks, and service provider networks using Fast and Gigabit Ethernet interfaces. The access switches support physical stacking, VLANs, and multicast groups, as well as advanced security features.

Battery backup power supply MES1124MB switches can use external battery power to keep working in case of a 220V power outage.

The switches have a power supply unit that can charge the battery when the 220V power line is available. The power system monitors the power line and notifies of power source switching. Surge protection

MES switches have effective protection technology against voltage surges (up to 6 kV) caused by lightning strikes.
