5.19.2 Configuring an FE-100TX Interface

In normal operation, a port with an FE-100TX interface automatically establishes a link with the device at the other end of the segment and no user setup is required. Section 5.19.3 and Section 5.19.4 provide instructions for manually configuring the port with an FE-100TX installed.

5.19.3 Setting the FE-100TX Operational Mode

Use this field to set the active technology. This field steps between Auto-Negotiation, 10BASE-T, 10BASE-TFD (full duplex), 100BASE-TX, and 100BASE-TXFD (full duplex). If Auto-Negotiation is selected, the FE-100TX automatically sets the active technology. To manually set the active technology through Local Management, proceed as follows:

1.Use the arrow keys to highlight the Desired Oper. Mode field.

2.Use the SPACE bar to select the desired mode. Press ENTER. If any mode other than Auto-Negotiation is selected, the port only operates in the chosen mode and auto-negotiation is disabled.

3.Use the arrow keys to highlight the SAVE command. Press ENTER. The message “SAVED OK” displays and Local Management saves the changes to memory. The selected mode is displayed in both the Desired Operational Mode field and the Current Operational Mode field.

5.19.4 Setting the FE-100TX Advertised Ability

During normal operation, a port (7 or 8) with an FE-100TX auto-negotiates to the highest speed possible. Under some circumstances, the Network Administrator may want the port to advertise only some of the available modes and not operate in other modes. This field steps between 10BASE-T, 10BASE-TFD (full duplex), 100BASE-TX, and 100BASE-TXFD (full duplex). To set the advertised ability, proceed as follows:

1.Use the arrow keys to highlight the Advertised Ability field.

2.Use the SPACE bar to select the desired mode.

3.Use the RIGHT-ARROW key to move across to the Enabled/Disabled field to the right of the selection.

6H129-08, 6H128-08 specifications

Cabletron Systems was a notable provider of networking hardware in the 1990s, specializing in solutions that enabled enterprises to build robust and scalable networks. Among their product offerings were the models 6H128-08 and 6H129-08, which were designed to meet the needs of demanding networking environments.

The 6H128-08 is an Ethernet hub that supports up to 128 ports. This model is particularly recognized for its reliability and performance in connecting numerous devices within a local area network. One of the main features of the 6H128-08 is its support for both 10BASE-T and 100BASE-TX Ethernet standards, allowing it to handle varying data transmission speeds and ensuring compatibility with older and newer devices. This dual support features made it particularly appealing for businesses transitioning from older network technologies to faster Ethernet connections.

In terms of technology, the 6H128-08 leverages a centralized architecture which reduces network collision domains. This design contributes to improved network performance by allowing simultaneous data transmission from multiple devices. The hub features a range of LEDs that provide real-time status updates on port connectivity and data transmission activity. This allows network administrators to easily monitor and troubleshoot connectivity issues.

The 6H129-08 is often paired with the 6H128-08, functioning effectively as an additional port expander or in cascading configurations. This model also supports 128 ports and offers identical compatibility with the Ethernet standards mentioned, ensuring seamless integration in larger network setups. An important characteristic of the 6H129-08 is its enhanced fault tolerance, which is vital in mission-critical environments where network downtime must be minimized.

Both models are equipped with various management features, enabling network administrators to configure settings and optimize performance easily. The ability to use SNMP for network management supports monitoring and managing the entire network from centralized software applications.

Overall, the Cabletron Systems 6H128-08 and 6H129-08 stand out for their robust performance, extensive port capabilities, and compatibility with multiple Ethernet standards, making them suitable for enterprises looking to build or expand their networking infrastructure. These products reflect Cabletron's commitment to reliability and innovation in the field of networking hardware.
