Ethernet Access Switch MES2428B

Mass production

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 access 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 can be equipped with a rechargeable battery to ensure power supply in case of the 220 V primary network connection loss. The switches are equipped with a power supply unit which allows the battery to be charged when 220 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.
