Huawei CloudEngine S5731‑L48P4S Full English Product Description

Product Overview

Key Features

1. Port & PoE Hardware Configuration

   48×10/100/1000BASE‑T RJ45 ports comply with IEEE 802.3bt PoE++ standard, providing up to 60 W per‑port output power for high‑power PD terminals such as Wi‑Fi‑6/7 wireless APs, high‑definition IP cameras and multi‑media IP phones. 4×GE SFP slots accept FE or GE SFP transceivers for long‑distance fiber uplink interconnection to parent switch. Supports power input via external dedicated power adapter or optical‑electrical composite PoE supplied from central parent device. Fan‑less natural convection cooling achieves zero‑noise running. Supports DIN‑rail, wall‑mount and standard rack‑mount installation to adapt to diverse‑site deployment environments. Service ports integrate surge‑protection capability for stable operation in complex building access environments.
2. Layer‑2 Functions & Remote‑Unit Operation Characteristics

   Supports 4094 IEEE 802.1Q VLANs, MUX VLAN, Voice VLAN, Guest VLAN and GVRP VLAN registration protocol. Supports STP/RSTP/MSTP and Smart‑Link for link redundancy and millisecond‑level fast fail‑over. Supports LACP link aggregation, IGMP Snooping v1/v2/v3, broadcast/multicast/unicast storm suppression and port isolation. Works as SVF remote unit: zero‑configuration plug‑and‑play. All configurations are delivered centrally from parent switch. After hardware replacement, services restore automatically without manual on‑site configuration, greatly reducing O&M workload.
3. Forwarding and Service Processing Mechanism

   This remote‑unit switch only performs basic Layer‑2 data receiving and forwarding. All Layer‑3 routing, ACL, authentication, QoS and multicast service logic are processed on matched parent core‑aggregation switch. Supports large‑scale virtual port expansion for parent switches. Supports real‑time link‑fault detection and fast alarm reporting to central management node. Compatible with mainstream Huawei campus core and aggregation switches with required software version.
4. Security Capabilities

   All security policies are uniformly issued by parent switch. Supports inherited functions: 802.1X authentication, MAC‑based access authentication, DHCP Snooping, ARP anti‑attack defense, L2‑L4 ACL traffic filtering. No local independent user authentication database; all access‑control logic runs on the parent device.
5. QoS and O&M Capabilities

   QoS scheduling and remarking policies are distributed by parent switch. Provides Console debugging port for basic on‑site fault diagnosis. Device status, port statistics and alarm events are reported in real‑time to parent switch and can be managed by eSight network management system. Supports dying‑gasp power‑failure alarm function.
6. Hardware Design

   Fan‑less natural heat dissipation, eliminating fan‑relevant failure risks. Accepts external power‑adapter power supply or optical‑electrical PoE input. Supports multiple installation modes.
