Key benefits

MES2308P access switches - managed L2+ switches which have 24 ports of 10/100/1000BASE-T with PoE/PoE+ support and 4 ports of 10GBASE-R (SFP+)/1000BASE-X (SFP).

The switches are designed to connect end users to a largescale corporate network, small and medium business networks and to a service provider networks using 1G/10G Ethernet interfaces.

The switches support physical stacking, VLANs, multicast groups and advanced security functions.
