Huawei S5700-28C-SI Managed L2 Black

S5700-28C-SI Mainframe(20 GE RJ45,4 GE Combo,Dual Slots of power,Single Slot of Flexible Card,Without Flexible Card and Power Module) The S5700-SI series gigabit enterprise switches (S5700-SI) are next-generation energy-saving switches developed by Huawei to meet the demand for high-bandwidth access and Ethernet multi-service aggregation. Based on cutting-edge hardware and Huawei Versatile Routing Platform (VRP) software, the S5700-SI provides a large switching capacity and high-density GE ports to accommodate 10 Gbit/s upstream transmissions. The S5700-SI can be used 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 S5700-SI is easy to install and maintain, reducing workloads for network planning, construction, and maintenance. Featuring advanced reliability, security, and energy conservation technologies, the S5700-SI helps
enterprise customers build next-generation IT networks.

Stackable
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

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.

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.
