Ethernet Access Switches MES2428B Ethernet Access Switches MES2428B Key features Advanced L2 features Support for Multicast (IGMP Snooping, MVR) Advanced security functions (L2-L4 ACL, IP Source Guard, Dynamic ARP Inspection, etc.) Uninterruptible power supply via battery   The switches provide end users connection to networks of large enterprises, small and mid-sized businesses and service providers via Fast and Gigabit Ethernet interfaces. The switches support Virtual Local Area Networks (VLAN), multicast groups and advanced security functions. Uninterruptible power supply MES2428B switches are capable to use external power battery in order to provide uninterruptible operation in case of 220V power shutdown. The switches are equipped with power supply unit that allows charging storage battery if 220V supply line is available. The redundant power system provides monitoring for power supply line and notifies on power sources switching.  MES2428B Eltex Số lượng: 0 Cái
