Huawei CloudEngine S5735I‑48S4X Industrial‑Grade Layer 3 All‑Fiber Switch

Product Overview

Key Features

• High‑density all‑fiber port design: 48 × Gigabit SFP downlink slots, compatible with single‑mode / multi‑mode optical modules for long‑distance field terminal access; 4 × 10GE SFP+ uplink slots for high‑bandwidth interconnection to aggregation or core devices. Equipped with DI/DO hardware alarm terminal and RS‑485 industrial serial interface for on‑site signal interaction.
• Fan‑less rugged industrial hardware: Adopts passive natural convection cooling with no fans, IP40 enclosure, excellent shock‑vibration resistance, suitable for long‑term continuous running in unattended outdoor cabinets and industrial equipment rooms.
• Complete Layer 2 / Layer 3 protocol stack: Supports IPv4/IPv6 dual‑stack, static routing, OSPF, BGP, VRRP; abundant Layer‑2 functions including 802.1Q VLAN, STP/RSTP/MSTP, LACP link aggregation, IGMP Snooping, REP resilient ethernet protocol, IEEE 1588v2 PTP precision time synchronization for time‑sensitive industrial services.
• Multi‑dimensional security defense: Supports 802.1X / MAC authentication, DHCP Snooping, ARP anti‑spoofing, ACL filtering and DoS attack prevention, meeting strict access security requirements for OT‑IT converged industrial networks.
• Industrial‑grade electromagnetic compatibility: Complies with IEC 61000 series EMC standards, high port surge protection to resist lightning surges and voltage fluctuations under complex on‑site power supply conditions.
• High‑reliability power architecture: Hot‑swappable power modules with 1+1 redundancy; supports multiple input modes including AC, HVDC and wide‑range DC. DI/DO alarm terminal outputs hardware fault signals for remote monitoring of unmanned sites.
• Intelligent O&M capabilities: Supports iStack stacking, SVF super virtual fabric, Zero‑Touch Provisioning and Telemetry real‑time telemetry collection. Multiple management approaches: Console CLI, SSH, SNMP v1/v2c/v3, Syslog; compatible with Huawei iMaster NCE‑Campus for centralized management of mass distributed industrial devices.
