Magnum H80B and H80P Personal Hubs User Guide (07/95)

Consistent with IEEE 802.3 specifications, Personal Hubs will detect collisions, extend collision fragments, and automatically partition and re-connect individual ports in order to keep problems on one segment from causing downtime elsewhere on the network.

Personal Hubs include LINK and RX LEDs, located on top of the unit above each RJ-45 port, and one LED for DC power located at the rear near the external power supply connection. For observing operational information from the LEDs, it is easy to associate the status LEDs for each of the ports with the appropriate port plug.

2.2.1Magnum H80B Product Description

Magnum H80B Personal Hubs provide a simple and inexpensive solution for networking a personal multi-system office using 10BASE-T twisted pair cabling. They are perfect for sites that have ThinNet installed and need to wire additional office space for twisted pair.

Magnum H80Bs are also well suited for small- to-medium- size office or lab environments (up to eight persons) that need an independent Ethernet network. They operate as self-sufficient units

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.
