Ethernet Access Switch MES2420B-24D

MES2420 series switches provide end users connection to networks of large enterprises, small and mid-sized businesses and service providers via 2.5G/10G interfaces. 

Uninterruptible power
MES2420B-24D switches can be equipped with a rechargeable battery to ensure power supply in case of the 230 V primary power supply loss. The switches are equipped with a power supply unit which allows the battery to be charged when 230 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.
