Huawei CloudEngine S5731‑L8T4S Full English Product Description

Product Overview

Key Features

1. Port Configuration & Hardware Installation

   8×10/100/1000BASE‑T RJ45 GE electrical ports for terminal access. 4×GE SFP slots accept FE and GE SFP transceivers for fiber uplink interconnection towards central switch. Non‑PoE design, no PoE power output. Supports power supply by external power adapter or optical‑electrical composite cable PoE input from central device. Fan‑less natural heat dissipation, zero‑noise operation. Supports DIN‑rail, wall‑mount and desktop installation to adapt to diverse on‑site deployment environments华为企业业.... Service ports are equipped with surge‑protection capability for stable running in building access environments.
2. Layer‑2 Functions & Remote‑Unit Features

   Supports 4094 IEEE 802.1Q VLANs, MUX VLAN, Voice VLAN, Guest VLAN, GVRP and VLAN mapping. Supports STP/RSTP/MSTP, Smart‑Link for link redundancy protection. Supports LACP link aggregation, IGMP Snooping v1/v2/v3, broadcast/multicast/unicast storm suppression and port isolation. Operates as remote extension unit: zero local configuration, plug‑and‑play, unified managed by central switch. After device replacement, services automatically restore without manual configuration, greatly reducing on‑site O&M workload.
3. Forwarding & Service Capability

   All forwarding and service logic are completed on paired central switch. Remote unit only undertakes Layer‑2 data receiving‑forwarding task. Supports large‑scale remote‑unit virtualized expansion for central switch port capacity. Compatible with mainstream Huawei core and aggregation switches after corresponding version upgrade. Supports link fault detection and rapid alarm reporting to central management node.
4. Security Mechanism

   Inherit complete security policy delivered from central control switch, including 802.1X authentication, MAC‑based authentication, DHCP Snooping, ARP anti‑attack, L2‑L4 ACL traffic filtering. No independent local user authentication database; all access control is implemented on central switch.
5. QoS and O&M Capabilities

   QoS policies are uniformly issued by central switch. Supports Console debugging port for basic fault inspection. Real‑time status, alarm and statistical data are reported to central switch, managed by eSight network management system. Supports Dying‑gasp power‑failure alarm function.
6. Hardware Design

   Fan‑less natural convection cooling. Powered by external dedicated power adapter or optical‑electrical PoE input. Compact small‑form‑factor housing, supports DIN‑rail and wall‑mount installation.
