Key Specifications

IQS-402XSM is an 1G/2.5G/10G managed Layer 2 Ethernet switch. It provides 4 port of electrical 10M/100M/1G/2.5GBase-T via RJ-45s plus 2 ports SFP slots of 100M/1G/2.5G/10GBase-X which provide stable and reliable long-distance Ethernet transmission over optical fiber. Built to Industrial grade standards, the FANLESS design provides high MTBF in indoor environments of operating temperature from -10 to 60°C (14 to 160°F), and incorporates redundant 12/24/48VDC power input. With Din-Rail or wall mounting metal housings, these switches are perfect choices for heavy duty use in harsh environments, such as Industrial Factory Automation, Data Center Networking, Intelligent Transportation Systems (ITS) and are also suitable for many military and utility market applications where environmental conditions exceed commercial product specifications.

These managed switches also support a wide variety of Ethernet Layer 2 functions, including CTC Union proprietary μ-Ring, ERPS, MSTP, RSTP and STP. They also support Layer 2 IGMP, VLAN, QoS, ACL, Security, IPv6, bandwidth control, and port mirroring. Additionally, these switches can also be managed by CTC Union's SmartView™ Element Management System, which offers a user-friendly and centralized device management platform and provides administrators the ability to monitor and configure these connected switches remotely.
