48CHAPTER 3: SETTING UP FOR MANAGEMENT

4To open a Telnet session via the DOS prompt, enter the IP address of the Switch that you wish to manage in the following format:

>telnet xxx.xxx.xxx.xxx

(where xxx.xxx.xxx.xxx is the IP address of the Switch)

If opening a Telnet session via third party software you will need to enter the IP address in the format suitable for that software.

5At the login and password prompts, enter admin as your user name and press Return at the password prompt (or the password of your choice if you have already modified the default passwords).

If the login prompt does not display immediately, press Return a few times until it starts.

6If you have logged on correctly, the top-level menu of the command line interface for the Switch you wish to manage is displayed as shown in Figure 12 on page 41.

4250T, 4226T, 4228G specifications

The 3Com 4228G, 4226T, and 4250T are professional-grade network switches designed for businesses seeking to enhance their network infrastructure. These models offer robust performance and reliability, catering to various networking needs, from small offices to large enterprise environments.

The 3Com 4228G switch is a 28-port gigabit Ethernet switch designed for high-bandwidth applications. It provides 24 Gigabit Ethernet ports with 802.3af Power over Ethernet (PoE) capability, allowing devices such as IP phones and wireless access points to be powered directly through the Ethernet cables. This feature simplifies installation and reduces additional cabling costs. The switch also supports VLAN tagging for network segmentation, improving security and performance. Its advanced traffic management lets IT administrators prioritize network traffic effectively, ensuring critical applications receive the necessary bandwidth.

On the other hand, the 3Com 4226T is a 26-port gigabit Ethernet switch, primarily designed for environments requiring a high level of connectivity without PoE. It offers similar features to the 4228G, such as VLAN support and enhanced traffic management capabilities. The 4226T is ideal for businesses that do not require power over Ethernet yet need reliable, high-speed networking capabilities. With 26 ports, this switch is an excellent choice for medium-sized enterprises looking to upgrade their network infrastructure without overwhelming their existing resources.

The 3Com 4250T is a more advanced switch, offering 48 Gigabit Ethernet ports and a robust feature set suitable for more complex networking environments. It includes Layer 2 and Layer 3 functionality, allowing for advanced routing and switching capabilities, making it highly adaptable to various network designs. The 4250T also simplifies network management through its extensive configuration options and support for IPv6. Moreover, it features an efficient cooling system and reduced power consumption, aligning with today’s growing demand for energy-efficient solutions.

All three models utilize advanced technologies such as Spanning Tree Protocol (STP) for loop prevention, QoS mechanisms to prioritize traffic, and comprehensive security features to protect the network from unauthorized access. With their different port configurations and capabilities, the 3Com 4228G, 4226T, and 4250T switches provide exceptional performance and flexibility, making them ideal for businesses aiming to enhance their networking capabilities.
