Ethernet access switch MES2424FB

Mass production

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 from rechargeable battery

MES2424FB switches provide end users connection to networks of large enterprises, small and mid-sized businesses and service providers via 1G/10G interfaces.

The switches support Virtual Local Area Networks (VLAN), multicast groups and advanced security functions.

Uninterruptible power
MES2424FB switches can be equipped with a rechargeable battery to ensure power supply in case of the primary network connection loss. The switch is also equipped with a power supply unit which allows the battery to be charged when AC power is available. Power supply redundancy makes it possible to monitor the state of the primary network and notify of a power type switching.
