Description
The new generation of access switches MES2300B-48 connects end users to the network of large enterprises, small and medium businesses and telecommunications operator networks using 1G/10G.
The switch functionality provides physical stacking, support for VLANs, multicast groups and advanced security features.
The MES2300B-48 switch has the ability to connect a rechargeable battery supply to ensure guaranteed power supply in case of 230 V primary power network failure. The switch is equipped with a power module that allows charging the battery when 230 V is available. The backup power system makes it possible to monitor the state of the primary network and notify of a power type switching.
