GE UR8NH Industrial Ethernet Switch

Description

GE UR8NH is a high-performance hosted industrial Ethernet switch designed specifically for critical task control systems. As a GE Proficy ™ Part of the industrial automation suite, it serves as the backbone of secure, high bandwidth industrial networks, connecting field devices, programmable logic controllers (PLCs), and enterprise level systems. This switch supports layer 2/3 routing, virtual local area network (VLAN) segmentation, and advanced quality of service (QoS) functionality, prioritizing real-time control data over non critical traffic, making it ideal for smart factories and digital transformation plans.

UR8NH

The uniqueness of GE UR8NH lies in its ability to maintain industrial grade robustness while connecting operational technology (OT) and information technology (IT). Its compact DIN rail mounting design seamlessly integrates into crowded control panels, while redundant power inputs (24 VDC/120-240 VAC) and wide temperature tolerance range (-40 ° C to 75 ° C) eliminate single point failures in harsh environments. For system integrators, the intuitive web interface and command-line interface (CLI) configuration of switches simplify the deployment of distributed sites, while built-in network security features such as IEEE 802.1X authentication and access control lists (ACLs) protect the interconnected industrial ecosystem from evolving network threats.

UR8NH

Main features and advantages:
The GE UR8NH provides unparalleled performance through the combination of hardware robustness and intelligent network functionality. Its functional advantages include supporting up to [X] Gigabit Ethernet ports (SFP slots with fiber optic expansion), enabling high-speed data transmission in applications such as high-definition video surveillance or edge real-time machine learning analysis. Advanced QoS mechanisms ensure that time sensitive protocols (such as motion control commands) receive priority processing, reducing latency variations to sub millisecond levels, which is crucial for synchronous robot operations.

In terms of hardware, the switch is designed for durability: IP30 grade protective enclosure, shock/vibration resistance (IEC 60068-2), and electromagnetic interference resistance (EN 50155) capability. Its fanless design eliminates moving parts and reduces maintenance needs in dusty or oily environments such as food processing plants or car paint shops. In terms of compatibility, GE UR8NH supports industrial protocols such as Modbus TCP, EtherNet/IP, and IEC 61850 (for power systems), making it a universal choice for cross industry applications.

Long term reliability is supported by its redundant ring network topology, such as GE Proficy RapidRing ™） Further improvement is achieved to ensure the normal operation time of the network, with a fault switching time of ≤ 20 milliseconds. The mean time between failures (MTBF) of the switch exceeds [X] hours, and its thermal design optimizes heat dissipation without the need for active cooling, ensuring consistent performance over 10 years of operation. It is very suitable for industries with high equipment replacement costs or logistics challenges.

Installation and maintenance:
Before installing GE UR8NH, please ensure that the control cabinet meets the air circulation requirements to avoid thermal throttling in high-temperature areas. Use shielded Cat6/Cat7 cables for Ethernet connections to reduce electromagnetic interference (EMI) from motors or drives, and ensure proper grounding through the switch’s dedicated grounding terminal. For ring network topology settings, please pre configure RapidRing ™ Parameters (such as priority nodes) to optimize failover performance. Avoid mixing managed and unmanaged switches in the critical path to maintain QoS integrity.

For maintenance, it is recommended to use the built-in diagnostic tools of the switch (such as port error statistics, CPU/memory usage) for a biannual health check. Monitor VLAN traffic patterns to identify anomalies that may indicate network threats or hardware degradation. Firmware updates should be tested in a testing environment and then verified for compatibility with existing devices using GE’s Proficy software. In corrosive environments such as coastal facilities or chemical plants, protective coatings should be applied to power terminals and corrosion conditions should be checked quarterly. Regularly review access control lists (ACLs) to ensure that only authorized devices communicate with switches, thereby enhancing OT network security.
