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

5.0TROUBLESHOOTING

All Magnum Ethernet products are designed to provide reliability and consistently high performance in all network environments. The installation of Personal Hubs is a simple procedure (see Section 3.0, INSTALLATION); operation is very simple and is described in Section 4.0, OPERATION.

Should problems develop during installation or operation, this section should help to locate, identify and correct such problems. Please follow the suggestions listed below prior to contacting your supplier. However, if you are unsure of any procedure described in this section, or if the Magnum Personal Hub is not operating as expected, do not attempt to repair or alter the unit. Contact your supplier (or if unknown, contact Garrett Communications) for assistance.

5.1Before Calling for Assistance

1.If difficulty is encountered when installing or operating the Personal Hub, refer back to Section 3.0, Installation and Section 4.0, Operation. Check to make sure that the various other components of the network are operable.

2.Check the cables and connectors to ensure that they are of the RJ-45 type (not RJ-11 “telephone” type), have been properly connected, and the cables/wires have not been crimped or in some way impaired during installation.

3.Make sure that the DC power cord is properly attached to the unit, and that the external power supply unit is plugged into a functioning electrical outlet. Use the PWR LEDs to verify the unit is receiving proper power.

4.If the problem is isolated to a network device other than the Magnum Personal Hub, it is recommended that the problem device be replaced with a known good device. Verify whether or not the problem is corrected. If not, go to Step 5 below. If the problem is corrected, the Personal Hub and its associated cables are functioning properly.

5.If the problem continues after completing Step 4 above, contact your supplier of the Personal Hub unit (or if unknown, contact Garrett Communications) by fax, phone or email for assistance.

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.
