Switch Module

2Verify that at least one interface card of any type is installed in the CoreBuilder chassis in any interface card slots 3-6. Data is transferred between switch modules via a communications chip on an interface card.

3Verify that the Ethernet management ports in both switches are connected to the NMS station. They can either be connected through a hub to the NMS station or through an Ethernet interface card in the same chassis, such as the CoreBuilder 7400 High Density Ethernet/ATM interface card, to the NMS station.

During the procedure you will need to verify connectivity between the NMS station and the switch by pinging the switch module from the NMS station.

Connectivity between the switch module and its attached devices is established by a coldStart trap transmitted by the switch module when it boots. The coldStart trap causes a device to learn the MAC address of the switch module. However, there are certain devices, for example, a Solaris station, which will not learn a new MAC address for an IP when one already exists. If you are using one of these devices as an NMS station, and you are unable to ping the switch module, try erasing the switch module’s MAC address from the device’s ARP table and ping again.

4Verify that the RS-232 terminal line is connected to the console port on the main switch module.

Procedure Execution

1Reset the configuration of both switch modules by executing the CFGFRMAT.BAT file supplied with your software.

To execute the CFGFRMAT.BAT file proceed as follows:

a Perform the LMA command (1) SYS / (3) LOA / (3) LCL / 1 to put the system in Load Mode: Load.

b Reboot the switch using the LMA menu command: (1) SYS / (7) RBO. The switch will reboot in debug mode.

c Transfer the RS-232 cable to the service port of the main switch module.

dFrom a DOS window on the LMA terminal execute > cfgfrmat com speed

where “com” is the communications port you are using and “speed” is 115200 for a CoreBuilder 7000HD switch module and 57600 for a CoreBuilder 7000 switch module.

The 3Com 7000 also incorporates advanced Layer 3 routing capabilities. This feature enhances the efficiency of data transmission and bolsters the overall responsiveness of the network. By allowing routing functions to occur directly on the switch, it reduces latency and optimizes traffic flow, which is critical for applications requiring high availability, such as VoIP and video conferencing.

Security is another core characteristic of the 3Com 7000. It comes equipped with built-in security protocols and features such as Access Control Lists (ACLs) and VLAN support, which segregate network resources and protect sensitive data. These security measures ensure that only authorized devices can access specific segments of the network, thus fortifying the organization's information security posture.

In terms of management, the 3Com 7000 offers an intuitive interface for monitoring and controlling network operations. It supports various management protocols and software, which facilitate streamlined administration and configuration. This ease of management can significantly reduce the operational burden on IT staff, allowing them to focus on strategic initiatives.

Additionally, the 3Com 7000 is designed for high performance. It supports extensive bandwidth and low-latency communications, making it ideal for high-demand applications. The ability to handle multiple simultaneous connections without compromising speed makes it an excellent choice for enterprises that rely on real-time data processing.

In summary, the 3Com 7000 is a sophisticated networking solution characterized by its modularity, advanced routing capabilities, robust security features, user-friendly management, and high performance. These attributes make it a compelling choice for enterprises looking to enhance their networking infrastructure for a competitive edge.
