Huawei IE4000‑8P4S Industrial Managed PoE Ethernet Switch

Product Overview

Key Features

• Industrial‑grade fanless hardware design: Compact metal enclosure, DIN‑rail mounting support, fanless passive cooling. Wide operating temperature range from ‑40 °C to +75 °C. Dual‑redundant DC power input prevents single‑point power failure. Built‑in alarm relay output for fault alert. 8 PoE+ ports comply with IEEE 802.3af/at standard, supplying power to remote powered devices.
• Complete Layer‑2 & advanced Layer‑2+ feature set: Supports 802.1Q VLAN, Voice VLAN, port‑based VLAN, STP/RSTP/MSTP, LACP link aggregation, IGMP Snooping, static multicast. IPv4/IPv6 static routing, DHCP server/client/relay, port isolation, QinQ for industrial multi‑service access.
• PoE intelligent management: PoE power budget management, per‑port PoE enable/disable, PoE priority, power‑over‑limit protection, PoE watchdog for automatic device recovery.
• Multi‑dimensional security capabilities: 802.1X port authentication, MAC address filtering, port security, ACL filtering, storm suppression for broadcast/multicast/unknown‑unicast traffic, SSH, SNMPv3 to secure management access.
• Reliability for industrial scenarios: Supports ERPS ring protection, MRP, LLDP, fault alarm output. High EMC performance against surge, electrostatic and electromagnetic interference to adapt to noisy industrial sites.
• Flexible operation & maintenance: Supports CLI, Web‑GUI, SNMP, RMON, log output. Compatible with Huawei eSight network management system for batch device deployment, status monitoring and fault diagnosis.
