3.Use the arrow keys to highlight the SAVE command at the bottom of the screen. Then press ENTER. The warning screen shown back in Figure 5-19displays.

4.Use the arrow keys to highlight the YES command and press ENTER. The changes are saved to memory, and the module reboots.

5.15.11 Configuring the COM Port

Before altering the COM port settings, ensure that a valid IP

Section 5.15.1.) Read this entire COM port configuration

 

 

section before changing the settings of the COM port.

The 6H12X-08 COM port supports the following applications:

NOTE

Refer to the Release Notes included with the 6H12X-08 to verify which COM Port applications are currently supported.

Local Management connections

American Power Conversion Uninterruptible Power Supply (UPS) connections

To configure the COM port, proceed as follows:

1.Use the arrow keys to highlight the COM field.

!

CAUTION

Do NOT disable or alter the settings of the COM port while operating the current Local Management connection through a terminal. Altering the COM port settings disconnects the Local Management terminal from the port, and ends the Local Management session.

2.Press the SPACE bar to choose either ENABLED or DISABLED. The COM port must be ENABLED if it will be used for Local Management or UPS applications. Select DISABLED if you wish to disable the COM port for additional module security.

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.
