Ethernet Access Switch MES2448B

Mass production
Key features
  • Advanced L2 features
  • Support for Multicast (IGMP Snooping, MVR)
  • Uninterruptible power supply from rechargeable battery
The Ethernet access 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
MES2448B switches 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.
