FUNCTIONAL DESCRIPTION:

IS420ESWBH3AE is a 16-Port 10/100 Base Ethernet IONet Switch manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Gas Turbine Control Systems. The ESWx Industrial Ethernet Switch is designed for industrial applications, ensuring reliable and high-speed Ethernet communication in harsh environments. It plays a crucial role in turbine control systems by enabling seamless data exchange between control, monitoring, and safety devices. Featuring 8 ports with 10/100BASE-TX, the ESWB Ethernet switches are optimized for real-time industrial control and are essential for all IONet switches in Mark VIe & VIeS safety control systems. This DIN-Rail mounting module is engineered for speed and functionality, offering key features to meet industrial networking demands.

ETHERNET SWITCH FLOW CONTROL:

The switch supports flow control between devices, utilizing IEEE-defined pause packets to manage data transmission. It only sends pause packets when necessary for flow regulation on a port. Designed for high reliability, it exceeds 4 million hours of Mean Time Between Failures (MTBF) at 35°C (95°F) in a ground-fixed, controlled environment.

CONFORMANCE CRITERIA FOR ETHERNET SWITCH:

The packet traffic can be synchronized by IEEE 1588 timing and triggered to initiate within a 1-microsecond packet start window. The switch’s capability and conformance are tested to meet the following four criteria:

• Multicast packet load initiated on one port without IEEE 802.3x flow control.
• Multicast packet load initiated on one port with IEEE 802.3x flow control.
• Multicast packet load distributed across all ports, with the packet count per port averaging the required amount based on the total number of switch ports, without IEEE 802.3x flow control.
• Multicast packet load distributed across all ports, with the packet count per port averaging 200, and IEEE 802.3x flow control negotiated on half the ports.

FREQUENTLY ASKED QUESTIONS:

How does the switch support flow control?

The switch uses IEEE 802.3x flow control mechanisms to regulate data transmission. It can receive and honor pause packets sent by connected devices, helping to prevent packet loss due to network congestion. The switch only sends pause packets when necessary to manage traffic efficiently on a port. This ensures stable communication in high-demand industrial control networks.

What is the Mean Time Between Failures (MTBF) of this switch?

The switch is engineered for high reliability, exceeding 4 million hours of MTBF at an ambient temperature of 35°C (95°F) in a ground-fixed, controlled environment. This extended operational lifespan makes it suitable for mission-critical applications where network downtime must be minimized.

How does the switch handle multicast traffic?

The switch is optimized for industrial control networks that rely on multicast traffic. It can initiate multicast packet loads on a single port or distribute them across multiple ports, depending on the network configuration. When flow control is not enabled, the packet count per port is averaged based on the total number of ports.
