Product Overview JHA-SMW0648 series L3 managed switches are designed to form highly accessible, scalable and robust networks. With an extensive suite of routing protocols, 10Gbps wired speeds, physical stacking technology, diverse management features and an optional redundant external power unit,JHA-S4806MG series provide a reliable, secure and cost-effective solution for enterprise, campus and ISP networks. JHA-SMW0648 series switches support Layer 3 routing protocols that include Static Routing, RIP, OSPF and VRRP, helping to build scalable, reliable networks. Multicast routing protocols such as PIM-SM and PIM-DM guarantee efficient routing for multicast groups.With different port forms including Gigabit Ethernet, SFP Slots, 10G SFP+ Slots,JHA-SMW0648 Series switches are capable of high switching capacity for the network. With all units identified by a simple IP address, the stack can be easily configured and monitored. JHA-S4806MG series switches provide 3 kinds of out-of-band management ports: RJ45 console ports, Micro-USB console ports and RJ45 out-of-band management ports. Micro-USB console ports are designed for those laptop computers which do not support the RS232 (DB9) interface. Customers can use a USB cable to manage switches through the CLI (command-line interface). The RJ45 out-of-band management port is used solely for web management, leaving the RJ45 ports free for data transmission. Highlights - Abundant Layer 3 routing protocols including RIP/OSPF/VRRP to support a scalable network - True physical stacking technology supports up to 8 switches for scalability and efficient redundancy -10 Gigabit Ethernet uplink ports ensure smooth data delivery for high-bandwidth applications- 2 power units minimize downtime - PIM-SM/PIM-DM/IGMP Snooping for reliably stable video quality - RJ45/Micro-USB Console ports and an out-of-band management port provide a range of management options - A USB 2.0 port makes it easy to import files and restore configurations Physical Stacking Technology With different port forms including Gigabit Ethernet, SFP Slots, 10G SFP+ Slots, JHA-MWS0424Series switches are capable of high switching capacity for the network.
