Huawei CloudEngine S5751‑L48P4S Full English Product Description

Product Overview

Key Features

1. Port, PoE and Hardware Configuration

   48×10/100/1000BASE‑T auto‑negotiation RJ45 ports comply with IEEE 802.3at PoE+ standard, supplying power for PD devices including Wi‑Fi‑6/7 wireless APs, IP surveillance cameras and multimedia IP phones. 4×GE SFP slots support FE/GE optical transceivers for long‑reach fiber uplink interconnection. Built‑in fixed AC power supply provides total PoE budget for PoE‑powered terminals. Intelligent variable‑speed fan dynamically adjusts rotation speed to balance heat dissipation and acoustic noise. Service ports deliver surge‑protection capability to guarantee stable running under complex building‑site environments. Adopts standard 19‑inch 1U rack‑mount chassis for cabinet installation.
2. Rich Layer‑2 Functions

   Supports 4094 IEEE 802.1Q VLANs, MUX VLAN, Voice VLAN, Guest VLAN, GVRP and VLAN mapping. Implements STP/RSTP/MSTP, Smart‑Link and RRPP ring‑protection protocols for millisecond‑level link fail‑over recovery. Supports LACP link aggregation, IGMP Snooping v1/v2/v3, MLD Snooping, broadcast‑multicast‑unicast storm suppression and port isolation. Works with central switch to realize SVF super virtual fabric, simplifying campus network architecture and lowering deployment and O&M workloads.
3. Forwarding & Virtualization Functions

   As remote‑unit device, service data traffic is centrally forwarded by paired central switch. Supports VBST compatible with PVST+ protocol, LNP link negotiation and VCMP VLAN centralized management. All service configurations, access authentication and QoS policies are issued by central switch to implement lean‑mode two‑tier campus networking. MAC‑address‑table capacity is managed uniformly by central switch.
4. Comprehensive Security Mechanism

   Supports 802.1X authentication, MAC‑based authentication, Portal authentication, AAA / RADIUS / HWTACACS access control, managed by central switch. Provides DHCP Snooping, ARP anti‑attack, DoS‑attack defense and port‑security functions. L2‑L4 ACL realizes flexible traffic filtering. Supports SSHv2 and HTTPS for secure encrypted management access.
5. Powerful QoS and Intelligent O&M Capabilities

   Multiple priority queues per port, supporting SP / WRR / WFQ queue‑scheduling algorithms. Supports port‑based rate‑limiting, two‑rate three‑color CAR, 802.1p / DSCP remarking. Provides Console port, Mini‑USB console, Web‑GUI, Telnet, SSH, SNMP v1/v2c/v3 and RMON. Compatible with eSight and iMaster NCE‑Campus network‑management platforms, supporting PNP zero‑touch deployment. Supports EEE energy‑efficient Ethernet for low‑power‑consumption operation.
6. Hardware Design

   Intelligent variable‑speed fan cooling; built‑in AC power supply. Standard 19‑inch 1U rack‑mountable chassis.
