Ethernet Access Switch MES2448B

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.
