4.0OPERATION

This section details the various operational features of Magnum Personal Hubs, including a description of the LED indicators. All Personal Hubs are fully compliant with the Ethernet Version 2/IEEE 802.3 Repeater Specification for CSMA/CD 10 Mbps operation and will function accordingly.

4.1Functional Operation, Use of LED Indicators

Power On (PWR) LED: Illuminates GREEN to show functional DC power.

Link Status (LINK) LED (per port): Illuminates GREEN when

there is proper connectivity on the port's 10BASE-T network segment. Each LINK LED will turn off independently in the event that connectivity is lost between the ends of that segment or a loss of power occurs in the segment at either end.

Note: When the switchable port is wired for up-link to another hub, the LINK LED will normally be on when the up-link switch is set to the X position. With the up-link switch off (= position), the LINK LED is off as the up-link is disabled. This permits local operation of the Personal Hub with full bandwidth.

Receive Packets (RX) LED (per port): Illuminates GREEN

intermittently to indicate that data is being received from the segment. This provides a visual indication of network activity for re- assurance of normal operation, and is helpful in troubleshooting.

Partitioning and Re-connection: Personal Hubs will automatically

partition any port where 32 consecutive collisions occur or after 6.5 ms of continuous transmissions. Network integrity is checked every 800 ms and segment re-connection occurs after one 512-bit packet is transmitted without an error.

H80B, H80P specifications

GarrettCom's H80P and H80B series switches are robust networking solutions designed for demanding environments, such as industrial automation and telecommunications. Engineered to provide reliability, flexibility, and performance, these switches are ideal for applications that require durable and high-speed network connectivity.

One of the key features of the H80P and H80B models is their Layer 2 and Layer 3 capabilities, enabling seamless integration into existing networks. Both models support advanced routing protocols, including RIP, OSPF, and PIM, which enhance network efficiency and reliability. The switches also offer support for VLAN tagging, allowing for efficient traffic management and network segmentation, which enhances security and performance.

Another standout characteristic is their port configuration. The H80P model typically offers more ports than the H80B, accommodating a larger number of devices. Both models feature a mix of copper and fiber optic ports, providing versatility in connections and enabling long-distance data transmission without degradation of signal quality.

In terms of performance, the H80P and H80B support Gigabit Ethernet speeds, ensuring high bandwidth for data-rich applications. This feature is critical in industrial settings where real-time data transfer and low latency are essential. Furthermore, these switches incorporate Quality of Service (QoS) features to prioritize critical traffic and maintain optimal performance levels during peak usage times.

The construction of the H80P and H80B models is another important aspect that sets them apart. They are designed to withstand harsh environments, with rugged enclosures that provide protection against dust, moisture, and extreme temperatures. This durability makes them suitable for deployment in outdoor installations and factory floors, where operating conditions can be challenging.

Security is a significant aspect of network management, and GarrettCom addresses this need by integrating various security features into the H80P and H80B switches. They support authentication protocols such as RADIUS and TACACS+, ensuring that only authorized users can access the network. Additionally, features like port security and DHCP snooping further enhance protection against potential threats.

In conclusion, GarrettCom's H80P and H80B switches combine advanced features, robust technology, and specialized characteristics to offer reliable network solutions. Their versatility, performance, and durability make them an excellent choice for organizations seeking to improve their industrial networking infrastructure while ensuring security and efficiency.
