Ethernet Access Switch MES2420B-24D

Mass production

Bandwidth up to 200 Gbps
Up to 24 ports of 2.5GBASE-T
Advanced L2 features
L3 switches
Support for Multicast (IGMP Snooping, MVR)
Advanced security functions (L2-L4 ACL, IP Source Guard, Dynamic ARP Inspection and etc.)

MES2420 series switches provide end users connection to networks of large enterprises, small and mid-sized businesses and service providers via 2.5G/10G interfaces.

Uninterruptible power
MES2420B-24D switches can be equipped with a rechargeable battery to ensure power supply in case of the 230 V primary power supply loss. The switches are equipped with a power supply unit which allows the battery to be charged when 230 V power is available. Power supply redundancy system makes it possible to monitor the state of the primary network and notify of a power type switching.
