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 is a high-performance PoE + 10 Gigabit switch in the Huawei S6720 series. Its core advantage is its 'full-scenario adaptation for campus PoE access layer' – 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; total switching capacity ≥598Gbps, forwarding performance up to 216Mpps, supporting enterprise-level functions such as link aggregation, PoE intelligent management, and basic QoS, and featuring built-in 9KV surge protection + PoE power supply 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 'balance PoE power supply, bandwidth, and stability'.
S6720-56C-PWH-SI FAQ
Q1: Can the PoE power supply capability of the S6720-56C-PWH-SI meet the needs of high-definition surveillance?
A11: Fully meets the requirements. A single port provides 30W, supporting over 99% of 1080P/4K high-definition IP cameras. The total PoE power is ≥740W, and a single unit can stably power 40 high-definition cameras. PoE intelligent management helps prevent overload.
Q2: What are the core advantages compared to general PoE switches?
A2: Huawei original factory quality assurance, higher PoE power supply stability (multiple protections against overload, short circuit, and lightning), 10 Gigabit uplink without bandwidth bottlenecks, compatible with Huawei ecosystem devices, and provides original factory warranty and technical support.
Q3: Will there be insufficient power when all 48 ports are simultaneously powered on with PoE?
A3: No, the total PoE power is ≥740W, supporting 48 ports to connect to 15.4W standard PoE devices simultaneously, or 30 ports to connect to 30W PoE+ devices, meeting the needs of most campus PoE scenarios.

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.
