The Huawei S57EI series gigabit enterprise switches (S57EI) are next-generation energy-saving switches developed by Huawei to meet the demand for high-bandwidth access and Ethernet multi-service aggregation. Based on the cutting-edge hardware and Huawei Versatile Routing Platform (VRP) software, the S57EI provides a large switching capacity and high-density GE ports to implement 10 Gbit/s upstream transmissions. The S57EI is for use in various enterprise network scenarios. For example, it can function as an access or aggregation switch on a campus network, a gigabit access switch in an Internet data center (IDC), or a desktop switch to provide 1000 Mbit/s access for terminals. The S57EI is easy to install and maintain, reducing workloads for network planning, construction, and
maintenance. The S57EI uses advanced reliability, security, and energy conservation technologies, helping enterprise customers build a next generation IT network.
Dual hot swappable power supplies
The two power supplies works 1:1, backup power module will start to work when master fails. Dual power supplies design increases system reliability and service availability.
iStack is a technology that enables multiple devices supporting the stacking feature to function as a logical device. iStack has the following advantages:
1)Protecting investments during network capacity expansion
2)Simplifying configuration and management during capacity expansion: multiple physical switches form a logical switch
3)Improving system reliability by using the redundancy backup mechanism
4)Supporting link aggregation between member switches
5)Providing more ports and higher bandwidth
Flexible extended slots:
The switch provide two extended slots, one for an uplink subcard and the
other for for a stack card.
Uplink subcards: 4 * GE, 2 * 10GE, 4 * 10GE.
The extended slots provide flexible expansion for the switch.
Maintenance-free, easy deployment and effortless management
The product supports automatic configuration and plug-and-play, which dramatically reduces maintenance costs.
The product supports GARP VLAN Registration Protocol (GVRP), which dynamically distributes, registers, and propagates VLAN attributes to ensure correct VLAN configuration and reduce network administrator workloads.
Powerful surge protection capability
The product uses a Huawei-patented surge protection technique to prevent lightning-induced overvoltage.
All ports on the product have 6 kV of surge protection, making them eight times more lightning-proof than 4 kV switches. The Huawei patented surge protection technique greatly reduces the possibility of equipment being damaged by lightning, even in extreme situations or in scenarios where grounding is not feasible.
