Eltex ETHERNET ACCESS SWITCH MES2424B

ETHERNET ACCESS SWITCH MES2424B

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

MES2424B 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.
