ICS-G24S4X & ICS-G24S2X Industrial Core Switches

Industrial Core Switches

The ICS-G24S4X & ICS-G24S2X are Ethernet Core Switches that are equipped with 24 Gigabit SFP ports with 4 combo ports plus 2 or 4 10G SFP+ ports. ICS series models are all fanless with redundant isolated power supplies (2 AC, 2 DC, AC + DC) and can be mounted in 19 inch standard rack. They not only offer various layer 2 management functions (IGMP, VLAN, QoS , Security, IPv6, bandwidth control, port mirroring, cable diagnostic and Green Ethernet) but also support u-Ring redundancy protocol that can establish 14 independent rings for flexible applications, especially employed in backbone infrastructure. Housed in rugged rack mountable enclosures, ICS Series complies with many industrial-grade standards and are ideal for deployments in harsh environments to deliver mission-critical network services. Additionally, with high port density and Gigabit or 10 Gigabit high-speed feature on each port, ICS-G24S4X & ICS-G24S2X are a reliable and scalable solution for core layer or backbone applications.
