H3C S5570S-54S-PWR-EI-A L2+ Ethernet PoE+ Switch
 
S5570S-54S-PWR-EI-A: 48x10/100/1000BASE-T Ethernet ports (PoE+), 6x1G/10G BASE-X SFP+ ports.
 
Product OverviewH3C S5570S-EI is a new generation of high-performance, high-port density, high-security and easy-to-install intelligent managed Gigabit Ethernet switches developed by H3C using industry-leading ASIC technology, supporting IPv4/IPv6 dual-stack management and forwarding, supports static routing protocols and routing protocols such as RIP, OSPF, IS-IS, BGP, etc., and supports rich management and security features.
 
H3C Intelligent Resilient Framework 2 (IRF2)
H3C Intelligent Resilient Framework 2 (IRF 2) virtualizes multiple S5570S-EI switches into one virtual switch and provides the following benefits:
Scalability: IRF 2 allows you to add devices to the IRF 2 system easily. It provides a single point of management, enables switch plug-and-play, and supports software auto-update for software synchronization from the master to the new member devices. It brings business agility with lower total cost of ownership by allowing new switches to be added to the fabric without network topology change as business grows.
High availability: The H3C proprietary routing hot backup technology ensures redundancy and backup of all information on the control and data planes and non-stop Layer 3 data forwarding in an IRF 2 fabric. It also eliminates single point of failure and ensures service continuity.
Redundancy and load balancing: The distributed link aggregation technology supports load sharing and mutual backup among multiple uplinks, which enhances the network redundancy and improves link resources usage.
Flexibility and resiliency: The switch use standard GE ports instead of specialized ports for IRF links between IRF member devices. This allows customers to assign bandwidth as needed between uplink, downlink, and IRF system connections. In addition, an S5570S-EI IRF fabric can span a rack, multiple racks, or multiple campuses.
