Functional Description
IS420ESWH1A is an Ethernet Switch developed by GE. It is part of Mark VIe control system. The switch facilitates flow control among switches by adhering to IEEE standards for pause packets, both receiving and respecting them. It selectively transmits pause packets only when flow control is necessary on a particular port.
Product Features
- 802.3, 802.3u, and 802.3x Compatibility: The switch supports industry-standard Ethernet protocols, including 802.3 (Ethernet), 802.3u (Fast Ethernet), and 802.3x (Flow Control), ensuring smooth communication and compatibility with a wide range of Ethernet devices and networks. These standards facilitate communication over both 10 Mbps and 100 Mbps networks, making it ideal for integration into existing control systems.
- 10/100 Base Copper with Auto Negotiation: Supports both 10 Mbps and 100 Mbps Ethernet connections over copper cabling. The auto-negotiation feature allows the switch to automatically detect and establish the best possible connection speed based on the network’s capabilities. This feature ensures seamless operation, whether the devices are operating at 10 Mbps or 100 Mbps.
- Full/Half Duplex Auto-Negotiation: The switch can automatically negotiate between full and half-duplex modes, optimizing data transfer for network conditions. Full-duplex mode allows simultaneous sending and receiving of data, while half-duplex allows one-way communication at a time. This flexibility ensures optimal throughput depending on the network setup and device requirements.
- 100 Mbps FX Uplink Port: For high-speed connections to other network devices or switches, includes a 100 Mbps fiber uplink port. This feature is ideal for longer-distance communication within industrial environments, as fiber optics offer faster transmission rates and better protection against interference.
- HP-MDIX Auto Sensing: The HP-MDIX (Automatic Medium-Dependent Interface Crossover) technology eliminates the need for crossover cables by automatically detecting the required cable type (straight-through or crossover) and adjusting the connection. This feature simplifies installation and ensures reliable connections, even if cabling errors occur.
- LED indicators for Easy Monitoring:
- Link Presence: Verifies whether a network connection is established.
- Activity: Monitors data transmission and reception activity on the port.
- Duplex Mode: Indicates whether the port is operating in full or half-duplex mode.
- Connection Speed: Shows whether the port is connected at 10 Mbps or 100 Mbps.
- Additionally, the switch has a Power LED to indicate that the device is powered and operational.
- 256 KB Buffer with 4K MAC Address Support: Equipped with a minimum 256 KB buffer, which allows for efficient management of data packets during periods of heavy network traffic, reducing packet loss and ensuring smooth communication. The switch also supports up to 4,000 MAC addresses, enabling it to handle a large number of network devices and facilitating complex network setups.
- Flow Control with Pause Packets: The switch supports flow control by using pause packets to prevent data congestion. According to IEEE standards, it can both receive and transmit pause packets when necessary, ensuring that data flow between devices remains smooth and avoiding potential bottlenecks. This selective transmission of pause packets is only triggered when flow control is required on a specific port, allowing for more efficient network traffic management.
Conformance Criteria
- Initiation of Multicast Packet Load (Without Flow Control): The switch must demonstrate the ability to initiate the required Multicast packet load on one port, without IEEE 802.3x flow control being negotiated. This test assesses the switch's performance under standard operating conditions without flow control mechanisms in place.
- Initiation of Multicast Packet Load (With Flow Control): Similar to the first criterion, this test evaluates the switch's capability to initiate the required Multicast packet load on one port, but with IEEE 802.3x flow control negotiated. It assesses the switch's performance under conditions where flow control mechanisms are actively engaged.
- Initiation of Distributed Multicast Packet Load (No Flow Control): In this test scenario, the switch must initiate the required Multicast packet load distributed across all ports, ensuring that the packet count per port averages the required value per the number of switch ports. This test is conducted without IEEE 802.3x flow control enabled.
- Initiation of Distributed Multicast Packet Load (With Flow Control on Half Ports): Lastly, the switch's performance is evaluated when initiating the required packet Multicast load distributed across all ports, with the packet count per port averaging 200 per the number of switch ports. Notably, IEEE 802.3x flow control is negotiated on half of the switch ports in this scenario, providing a comprehensive assessment of the switch's performance under varied flow control configurations.
Attributes
- 100Base-FX Multi-mode Fiber Ports: This switch is equipped with two 100Base-FX multi-mode fiber ports, offering high-speed data transfer capabilities. These ports feature LC-type connections, ensuring reliable and secure connections for enhanced data transmission.
- Seamless Integration: As part of the Mark VIeS system, seamlessly integrates with other components and devices, enabling smooth communication and coordination across the entire system.
- Enhanced Data Transfer: The inclusion of multi-mode fiber ports facilitates fast and efficient data transfer, essential for real-time monitoring, control, and analysis within industrial environments.
- Reliability and Durability: Built to withstand the rigors of industrial settings, exhibits robust construction and reliability, ensuring uninterrupted operation even in demanding conditions.
- Scalability: The Mark VIeS system, offers scalability to accommodate evolving operational needs and system expansions, providing flexibility and adaptability over time.
