This is a Layer 3 Stackable Managed Gigabit Switch that provides high-density performance, Layer 3 static routing, RIP (Routing Information Protocol) and OSPF (Open Shortest Path First) with 10Gbps uplink and multiple SFP fiber interfaces delivered in a rugged, strong case. The administrator can flexibly choose the suitable SFP/SFP+ transceiver according to the transmission distance or the transmission speed required to extend the 10G network efficiently. Besides, with 128Gbps switching fabric, the SGS-6341-16S8C4XR can handle extremely large amounts of data in a secure topology linking to backbone or high capacity servers for ISP and enterprise VoIP, video streaming, and multicast applications. 24 x 100/1000BASE-X mini-GBIC/SFP slots. 8 x 10/100/1000BASE-T RJ45 copper ports, shared with Port-1 to Port-8. 4 x 10GBASE-SR/LR SFP+ slots, compatible with 1000BASE-SX/LX/BX SFP. RJ45 to DB9 console interface for switch basic management and setup. 1 x USB2.0 interface for configuration and firmware storage.
