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

to provide ThinNet and 10BASE-T Ethernet connectivity for local users and devices. Small independent networks built using Personal Hubs are easily expanded by adding hubs of equal or greater capacity via cascaded connections using the Up-Link switched port feature. The BNC port of the H80B provides 10BASE2 backbone connectivity if required.

The H80B's small size makes it very useful for demonstration situations in conference rooms and in exhibitions where a temporary network or network expansion is needed. It is handy as a piece of test equipment that can be easily inserted into a network to provide a test port, and then removed after the testing is done. The H80B Personal Hub takes up minimal space, uses minimal power, and is rugged enough to be carried in a coat pocket for possible emergencies.

The external power supply unit supplied with the H80B is one of two types; one version for AC input power of 115 vac 60 Hz, and one version for 230 vac 50 Hz. The 115 vac version has a small transformer integral with a convenience power outlet plug. The 230 vac version has a small transformer integral with an IEC-type power plug for a user-supplied AC power cord with a convenience power outlet plug. Both types include a lightweight DC power cord for connection to the Personal Hub's power jack.

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.
