48 Port gigabit +4 Port 10G SFP L3 Managed Industrial Switch

YH6448GST4-SFP switch is a high performance 48 Port gigabit + 10G SFP+ L3 core switch. It provides Static routing and dynamic routing with advanced hardware processing capacity. The machine adopts modular design, which supports up to 4 Port 10G SFP+, and retains the expansion ability to further support 10GE when realizing gigabit convergence or access. It supports IPv4/IPv6 hardware double stack and line speed forwarding, so that customers can easily cope with the coming IPv6 era, which provides high capacity exchange capacity. YH6448GST4-SFP switch has the operating temperature of -40℃ ~ 80℃, has the super firmness to adapt to all kinds of harsh environment, can also be very convenient to install in the machine room cabinet. The rack-mounted characteristics and wide temperature operation make the switch a plug and play industrial-grade device, providing a reliable and convenient solution for users to network their Ethernet devices
