3.5.2AUI Connections (Model H80P only)

The Magnum H80P is equipped with a rear DTE (male AUI) port which serves a dual purpose of supplying power to the unit and providing backbone connectivity.

NOTE: Since the H80P derives its power from this port, this connection must be completed before the unit will function, unless an optional external power supply is being used..

Before connecting the DTE port of the Magnum H80P, note that the maximum cable length of an AUI drop cable is 50m (165 ft).

The Magnum H80P DTE connector supports standard IEEE signals, summarized in Table 3.5.2.

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.
