48 port Gigabit Managed Layer 3 switch with 10GB and IP stacking | MSRP: $4,307


Gigabit L3 switch series with44 copper gigabit ports 4 ports combo gigabit copper / SFP ports, 2 X 10Gb stacking ports 2 open slots for 10Gb modules

The SS3GR50i is designed to operate at the core of an Enterprise network. These full featured switches are ideal for aggregating servers in the distribution layer of three tier networks, with high performance wire speed L2 switching and IPv4 and IPv6 L3 routing. 2 x 10Gb expansion ports using optional modules allow you to future proof your network. 8 units can be hardware stacked via an optional 10GB stacking cable offering up to 384 Gigabit ports per stack. IP stacking allows you to manage up to 36 units across your network with 1 IP address to form a solid backbone solution.
