The S5720I-SI series switches (S5720I-SI for short) are next-generation standard gigabit Layer 3 Ethernet switches that provide flexible full gigabit access and cost-effective fixed GE ports and 10GE uplink ports. The S5720I-SI was developed based on next-generation high-performing hardware and the Huawei Versatile Routing Platform (VRP). The S5720I-SI supports simplified operations and maintenance (O&M), intelligent stack (iStack) and flexible Ethernet networking. It also provides enhanced Layer 3 features and mature IPv6 features. The S5720I-SI supports high range of operating temperature, so the switch can be working in the outdoor cabinet in the very cold and very hot environments. S5720I-SI can be widely used in safe city, ETTx and other scenarios.

Q: Does Huawei S5720I-SI Switches support POE++ large power supply?
A: Yes, S5720I-12X-PWH-SI-DC and S5720I-28X-PWH-SI-AC both support PoE++, which provides up to 60 W power supply per port.
Q: Can S5720I-28X-PWH-SI-AC supports Super Virtual Fabric (SVF) function?
A: Yes, S5720I-28X-PWH-SI-AC switch with SVF function can virtualize the "Core/aggregation + Access switch + AP" structure into a logical device.
Q: Do I need to buy SFP Modules forS5720I-28X-PWH-SI-AC switch?
A:Yes, as S5720I-28X-PWH-SI-AC is an optical switch, the optical ports will not able to work without SFP module, if you don't have SFP module, you will need to purchase additional SFP Module.
Q: Can I get technical support from Thunder-link.com if we purchase Huawei CloudEngine S5720I-28X-PWH-SI-AC switch from you?
A: Yes, Thunder-link.com has experienced technical team on Huawei switches, however, you may need to purchase technical support service from us as by default we only provide one year hardware warranty.
