S6720-56C-PWH-SI

The Huawei S6720-56C-PWH-SI is a high-performance 10 Gigabit Ethernet (GE) fixed switch, part of Huawei’s S6720-SI series. This model is designed for demanding network environments, offering a mix of port speeds and Power over Ethernet (PoE++) capabilities, making it highly versatile.

Here’s a detailed breakdown of its features and applications:

Key Features and Specifications:

• Port Configuration:
  • 32 x 10/100/1000Base-T Ethernet ports: These are standard Gigabit Ethernet ports, suitable for connecting a wide range of network devices.
  • 16 x 100M/1G/2.5G/5G/10G Base-T Ethernet ports (Multi-Gigabit): These ports are a standout feature, automatically negotiating speeds from 100 Mbps up to 10 Gbps over existing copper cabling (Cat5e or Cat6 for multi-gigabit speeds, Cat6A/7 for full 10Gbps). This is ideal for supporting next-generation Wi-Fi 6/6E access points and other high-bandwidth devices.
  • All 48 copper ports (32 x 1G and 16 x multi-gig) support PoE++ (802.3bt). This means they can deliver substantial power (up to 90W per port, depending on the power supply configuration) to connected devices, eliminating the need for separate power sources. This is crucial for powering advanced Wi-Fi APs, IP cameras, video phones, and thin clients.
  • 4 x 10GE SFP+ Fixed Ports: These ports provide high-speed fiber uplinks to connect to the aggregation or core layer of the network, or to 10GE servers and storage.
• One Extended Slot: This slot provides flexibility for future expansion. It can accommodate various interface cards, such as:
  • 2-port 40GE QSFP+ interface card (e.g., ES5D21Q02Q00), for extremely high-bandwidth uplinks.
  • 4-port 10GE SFP+ interface card (e.g., ES5D21X04S01), for additional 10GE fiber connectivity.
• Dual Pluggable Power Supply Slots: The “PWH” in the model name indicates that it supports pluggable power modules with high PoE output. The “SI” implies it does not come with a pre-installed power supply. You would need to order specific AC or DC power modules separately (e.g., 580W AC PoE power module, 650W DC PoE power module, 1000W AC PoE power module, or 1150W AC PoE power module). The dual slots allow for 1+1 power redundancy, ensuring high availability and continuous operation even if one power supply fails.
• Performance:
  • Switching Capacity: 2.56 Tbit/s (Terabits per second). This ensures non-blocking, wire-speed forwarding across all ports.
  • Packet Forwarding Rate: 240 Mpps (Million packets per second). This indicates its robust ability to process a high volume of network packets efficiently.
• Reliability:
  • Supports 1+1 power redundancy and hot-swappable power modules and fan modules.
  • Features a wide range of reliability technologies including STP/RSTP/MSTP, RRPP, Smart Link, SEP, and G.8032 ERPS for millisecond-level link protection switchover.
  • Supports BFD for rapid fault detection.
  • Enhanced Trunk (E-trunk) for inter-device link aggregation.
• Security:
  • Comprehensive security features including defense against DoS, ARP, and ICMP attacks.
  • DHCP snooping, IP source check, and strict ARP learning.
  • 802.1X, MAC address authentication, and portal authentication for stringent user and device access control.
  • CPU defense mechanisms.
  • MACsec support for secure LAN communication.
• QoS (Quality of Service):
  • Advanced QoS capabilities for traffic classification, policing, shaping, and queue scheduling (WRR, DRR, PQ, WRR+PQ, DRR+PQ) to prioritize critical services like voice and video.
• Management and Operation:
  • Supports iStack technology, allowing multiple physical switches to be virtualized into a single logical switch for simplified management, enhanced scalability, and improved network resilience. MultiGE, 10GE SFP+, or 40GE QSFP+ (via extended slot) ports can be used as stack ports.
  • Managed via CLI, Web-based NMS, and SNMPv1/v2c/v3.
  • Features like automatic configuration, plug-and-play, and USB-based deployment for simplified operations.
• Layer 3 Routing Capabilities (Standard Version – SI):
  • IPv4: Static routing, RIPv1/v2, OSPF, IS-IS, BGP, ECMP, VRRP, policy-based routing.
  • IPv6: Static routing, RIPng, OSPFv3, IS-ISv6, BGP4+, VRRP6.

Typical Applications:

• High-Speed Wireless Device Access: Its abundant multi-gigabit ports with PoE++ are perfectly suited for deploying and powering a large number of Wi-Fi 6/6E access points, eliminating network bottlenecks and simplifying cabling.
• Campus Network Access/Aggregation: Can function as a high-performance access or aggregation layer switch in large enterprise or educational campus networks, supporting a mix of traditional and next-generation devices.
• 10GE Data Center Server Access: Capable of providing high-density 10GE access for servers in data centers, with the added benefit of PoE for server management or other powered devices within the rack.
• Converged Networks: Ideal for environments where high bandwidth, significant PoE power, and robust Layer 2/3 features are all required for a unified network infrastructure.

In summary, the Huawei S6720-56C-PWH-SI is a versatile and powerful switch designed to meet the growing demands of modern, high-density networks, particularly those leveraging multi-gigabit speeds and extensive PoE capabilities for advanced wireless deployments and converged services.
