S5972 High-Density 100G/400G Data Center Spine Switch – Technical Specifications

Parameter Category	Specification Details
Model Number	S5972 (Series Name, e.g., H3C S5972-32CQ)
Switch Type	Fully Managed Layer 3 Data Center Spine / Super-Spine Switch
Hardware Ports	Common configurations include: • 32 x 400G QSFP-DD ports (Super-Spine role) • 64 x 100G QSFP28 ports (via breakout, Spine role) (The “72” often signifies a flexible, ultra-high-density design for core fabric roles)
Port Breakout	Extensive breakout support is a key feature: • A 400G QSFP-DD port can break out into 2x 200G, 4x 100G, or 8x 50G ports. • This allows the switch to be adapted for various spine or super-spine roles.
Switching Capacity	~12.8 Tbps (Terabits per second) or higher (non-blocking) e.g., 32x400G = 12.8 Tbps full duplex.
Forwarding Rate	~9,600 Mpps (Million packets per second)
MAC Address Table	512K – 1M entries
Packet Buffer Memory	64 MB – 128 MB (Massive deep buffers for AI/ML and large-scale data center traffic)
Jumbo Frame Support	12KB
Layer 2/3 Features	Designed for massive-scale leaf-spine fabric: • BGP (Border Gateway Protocol) for EVPN control plane • OSPF/IS-IS for underlay routing • VXLAN/EVPN (Hardware-based VTEP) • ECMP with 32+ paths • Basic VLAN, LACP, etc.
Data Center Features	• VXLAN/EVPN (Full hardware-based support) • RDMA over Converged Ethernet (RoCE) support with explicit congestion notification (ECN) • In-band Network Telemetry (INT) support • GPUDirect® Support for AI/ML workloads • Advanced Traffic Engineering
Quality of Service (QoS)	• 8-16 priority queues per port • Advanced congestion management (ECN, WRED) • Precision timing protocol (PTP) for synchronization
Security Features	• Hardware-accelerated ACLs (IPv4/IPv6) • Micro-segmentation support within the fabric • Management security (TACACS+, RADIUS, SSH, etc.)
Management & Automation	API-First Design. • RESTful API • NETCONF/YANG data models • Python SDK • Ansible, Chef, Puppet integration Traditional CLI and Web GUI are available but not the primary method.
Hardware Details	Power Supply: Dual or Quad, hot-swappable, high-wattage (2000W+ each) power supplies (AC/DC/HVDC). Power Consumption: 500W – 1000W+ (highly dependent on optic modules used). Cooling: Redundant, hot-swappable, variable-speed fans with advanced cooling designs. Dimensions (W x D x H): Standard 19-inch rack-mountable; typically 1U or 2U height.
Operating Temperature	0°C to 40°C (32°F to 104°F)
Operating Humidity	10% to 90% non-condensing
Certifications	CE, FCC, RoHS
