The S series fixed Ethernet switches integrate the access and transmission functions to provide reliable access/aggregation and high-quality transmission of services on enterprise networks. The switches are built on an integrated hardware platform, and their hardware system consists of the chassis, power module, fan module, extended cards, and Switch Control Unit (SCU).
The S series fixed Ethernet switches are available in a variety of models for you to choose based on your network requirements.
S6700 Series Switches Characteristics The S6700 series Ethernet switches are next-generation 10G fixed switches. The S6700 can function as a core switch on a campus network. The S6700 has industry-leading performance and provides line-speed 10GE access ports and line-speed 40GE even 100GE uplink ports. It can function as a core switch on a campus network to provide 40 Gbit/s even 100 Gbit/s traffic aggregation.
The Huawei S6720-56C-PWH-SI-AC is a high-performance PoE + 10 Gigabit AC-powered switch from the Huawei S6720 series. Its core advantage is 'full compatibility with PoE access layer in AC-powered scenarios'—48 Gigabit Ethernet ports support PoE + power supply (maximum power of 30W per port, total PoE power ≥740W), 4 10 Gigabit optical ports + 4 Gigabit optical ports for flexible uplink and expansion, adapting to 3000-5000 terminals; AC input voltage supports a wide range of 100-240V, total switching capacity ≥598Gbps, forwarding performance up to 216Mpps; it supports PoE intelligent power allocation, link aggregation, basic QoS and other functions, and features built-in 9KV surge protection + PoE/AC dual protection design, with an annual failure rate of <0.03%. It is the preferred choice for office APs, IP monitoring, and campus access layers that rely on AC power, 'balancing power supply stability, bandwidth and practicality'.
S6720-56C-PWH-SI-AC FAQ
Q1: What are the advantages of AC power supply compared to DC power supply?
A1: AC power supply is directly compatible with ordinary AC mains power and office park power grids, eliminating the need for additional DC power modules. This results in lower deployment costs, stronger compatibility, and suitability for environments without dedicated DC power supply.
Q2: Is stability guaranteed when 48 ports are simultaneously operating with PoE power supply and wide AC voltage input?
A2: Yes, it features built-in AC power supply voltage regulation and dual overload/short circuit protection for PoE. The wide voltage range adapts to grid fluctuations, and the total PoE power is ≥740W, stably supporting multiple devices operating simultaneously without the risk of power outages.
Q3: Can this device meet the PoE power supply and bandwidth requirements of 4K high-definition surveillance cameras?
A3: Fully compatible. A single port's 30W power supply meets the power requirements of a 4K camera, and the 10 Gigabit uplink provides ample bandwidth. Combined with QoS traffic scheduling, it ensures smooth real-time video transmission from multiple 4K cameras.

3 m and 10 m SFP+ AOC cables
0.5 m and 1.5 m SFP+ dedicated stack copper cables (used for zero-configuration stacking, supported in V200R011C10 and later versions)
NOTE:
The four 10GE SFP+ ports on the front panel cannot be used simultaneously with ports on the rear card (except the 4-port 10GE rear card).
If a rear card other than a 4-port 10GE rear card is installed in the switch, only the ports on the front panel can be used by default.
V200R011 version: To use the port on the rear card, run the set device port-on-card enable command. Then the four 10GE SFP+ ports on the front panel cannot be used.
V200R012 and later versions: To use the port on the rear card, run the undo set device port-config-mode port-on-board enable command. Then the four 10GE SFP+ ports on the front panel cannot be used.
