Ethernet Access Switch MES2408B

Mass production
Key features
  • Advanced L2 features
  • Support for Multicast (IGMP Snooping, MVR)
  • Advanced security functions (L2-L4 ACL, IP SourceGuard, Dynamic ARP Inspection, etc.)
MES2408B switches provide connection of end users to networks of large enterprises, small and mid-sized businesses and service providers via Gigabit Ethernet interfaces.
The switches support Virtual Local Area Networks (VLAN), multicast groups and advanced security functions. 

Uninterruptible power
MES2408B switch can be equipped with a rechargeable battery to ensure power supply in case of the 220 V primary network connection loss. The switch is also 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.
