92CHAPTER 6: UPGRADING SOFTWARE

The number 1.04 will match the version number in the bootrom file, which is 01_04. If the version number of the file matches the displayed version, there is no need to download the bootrom (.btm) file.

File Distribution

The following commands enable you to distribute your downloaded files to the remaining switches in the fabric:

1To copy the new software file to each switch in the fabric, enter the following from User View:

copy unit1>flash:/s4a03_01_04s56.app unit2>flash:/

Replace unit2 with unit3 and so on for each switch in the fabric.

2To copy the new default configuration file to each switch in the fabric, enter:

copy unit1>flash:/3ComOScfg.def unit2>flash:/

Replace unit2 with unit3 and so on for each switch in the fabric.

3To copy the new Web user interface file to each switch in the fabric, enter:

copy unit1>flash:/s4e01_04.web unit2>flash:/

Replace unit2 with unit3 and so on for each switch in the fabric.

4To copy the new Bootrom firmware file to each switch in the fabric, enter: copy unit1>flash:/s4e01_04.btm unit2>flash:/

Replace unit2 with unit3 and so on for each switch in the fabric.

Command Line Interface Switch Setup

1To set the switch to boot from the new software you have downloaded, enter the following:

boot boot-loader unit1>flash:/s4a03_01_04s56.app

To set the remaining switches in the fabric to boot from the new software, replace unit1 with unit2 and so on for each switch in the fabric.

2To set the switch to load the new bootrom firmware, enter: boot bootrom unit1>flash:/s4e01_04.btm

5500G-EI, 5500-EI specifications

The 3Com 5500-EI and 5500G-EI series are advanced Ethernet switches designed for enterprise networks, catering to the growing demand for high-performance, secure, and scalable networking solutions. These switches are particularly suited for large organizations that require robust management capabilities and high-density connectivity.

One of the key features of the 5500-EI and 5500G-EI models is their modular architecture, which allows businesses to tailor the switch configuration to their specific needs. With options for various interface modules, including Gigabit Ethernet and PoE (Power over Ethernet), these switches can support diverse networking requirements and facilitate the gradual expansion of the network infrastructure.

The Series offers advanced Layer 2 and Layer 3 switching capabilities. Layer 2 features include VLAN tagging, trunking, and Spanning Tree Protocol (STP) to ensure efficient traffic management and network segmentation. On the Layer 3 front, the switches support static routing, RIP, and OSPF, enabling dynamic routing protocols for better traffic flow and load balancing. These features together enhance the performance and reliability of enterprise applications.

Security is another vital aspect of the 3Com 5500-EI and 5500G-EI series. The switches come equipped with robust security features to protect sensitive data and maintain compliance. These include MAC address filtering, access control lists (ACLs), and support for 802.1X authentication. Additionally, the devices support secure management protocols like SNMP v3, which enhances the security of management communications.

The 5500G-EI model stands out with its high-density port offerings, supporting up to 48 ports in a single switch, with an option for stacking to create a unified management platform across multiple switches. This flexibility allows organizations to leverage their existing infrastructure while scaling seamlessly in response to growing demands.

Another notable characteristic is the built-in IPv6 support, which positions the 3Com 5500-EI and 5500G-EI models favorably for future-proofing enterprise networks as the transition to IPv6 continues. This feature ensures that organizations can maintain connectivity as devices increasingly adopt the newer protocol.

In conclusion, the 3Com 5500-EI and 5500G-EI series offer a comprehensive suite of features and technologies designed for high-performance enterprise networking. With modularity, robust Layer 2 and Layer 3 capabilities, enhanced security measures, and a focus on scalability, these switches provide a solid foundation for modern corporate networks, accommodating future growth and technological advancements.
