The IQS-402XSM-4PH is a compact, industrial-grade managed Ethernet switch designed for demanding environments. It features 4 2.5G RJ45 ports, each supporting PoE+ with a total power budget of 120W, along with 2 versatile 1G/2.5G/10G SFP+ slots for high-bandwidth connectivity. This fanless switch offers exceptional reliability with a high mean time between failures (MTBF) and supports a wide operating temperature range, making it ideal for use in harsh industrial, transportation, military, and utility applications. Key features include advanced network management with support for multiple VLAN types, dynamic LACP link aggregation, IGMP snooping, QoS, and flexible security options like IEEE 802.1X, RADIUS, ACL, and more. It also offers multiple ring topologies (μ-Ring, μ-Chain, Sub-Ring) for reliable, redundant networking and includes full IPv6 support, CLI, web-based, and SNMP management. With redundant 48VDC power inputs and software upgrade capabilities via TFTP and HTTP, this switch is engineered for high-performance and high-availability in mission-critical systems.
