    Switch. 1.1 Introduction The GS2200-48 is a stand-alone layer 2 Gigabit Ethernet (GbE) switch. It comes with 44 100/1000 Mbps Ethernet ports, 4 Dual Personality interfaces (each consisting of one RJ-45 Gigabit port and one slot for a mini-GBIC transceiver (SFP module) with one port active at a time) and two mini-GBIC transceivers for fiber- optic uplink connections.
