IS421ESWAH1A is an ESW Series Ethernet Switch manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic Gas Turbine Control Systems. The Ethernet switch operates by using the MAC (Media Access Control) addresses of connected devices to forward data packets between them. When a device wants to send data to another device on the network, it addresses the data packet with the recipient's MAC address. The switch then examines this information and efficiently forwards the packet only to the appropriate port where the destination device is connected, rather than broadcasting it to all ports like a hub would do. This process improves network efficiency and reduces unnecessary traffic. An 8-Port Ethernet Switch is a popular choice for small to medium-sized networks or home networks where multiple devices need to be connected and require seamless communication. It provides a straightforward and effective way to expand the number of devices connected to the network when more ports are needed than what a router typically offers.


Eight Ethernet Ports: As the name suggests, the switch will have eight ports that allow you to connect up to eight network-enabled devices. These devices can include computers, printers, gaming consoles, smart TVs, IP cameras, and more.

Fast Ethernet or Gigabit Ethernet: Depending on the model, the switch might support either Fast Ethernet (10/100 Mbps) or Gigabit Ethernet (10/100/1000 Mbps) speeds. Gigabit Ethernet provides faster data transfer rates and is more suitable for high-bandwidth applications, such as video streaming or large file transfers.

Auto-Negotiation: The switch will likely have auto-negotiation capabilities, allowing it to automatically determine the best possible speed for each connected device based on its capabilities.

LED Indicators: Each port on the switch will have LED indicators that show the link status and activity, making it easier to identify which ports are currently in use.

Flow Control: The switch may support flow control mechanisms (such as IEEE 802.3x) to manage network traffic and prevent data loss during periods of congestion.

VLAN Support: Depending on the model and intended use, some switches may offer Virtual LAN (VLAN) support, which allows for the segmentation of the network into multiple logical subnetworks, enhancing security and network management.

What is an 8-port Ethernet Switch?

An 8-Port Ethernet Switch is a network device that allows you to connect up to eight Ethernet-enabled devices in a local area network (LAN). It facilitates communication between these devices by intelligently forwarding data packets based on their MAC addresses.

What do the LED indicators on the switch mean?

The LED indicators on the switch's ports show the link status and activity of each port. A steady green light indicates a successful link while flashing lights indicate data transmission or reception.
