case the upgrade process fails for any reason (for example, the connection between the computer and the Switch is lost while the new firmware is being copied to the Switch).

A progress screen displays while the upgrade is taking place.

The upgrade procedure can take a few minutes, and is complete when the progress bar has finished running and the Power LED has stopped flashing and is permanently green.

CAUTION: Do not interrupt power to the Switch during the upgrade procedure. If you do, the firmware may be corrupted and the Switch may not start up properly afterwards.

Initialize

To reset the Switch to factory default settings:

1Click Administration, then Initialize on the menu.

Administration Settings

You will lose all your configuration changes. The Switch LAN IP address will revert to the default IP address 169.254.x.y. (see “Automatic IP Configuration” on page 33). You may need to restart your computer to re-establish communication with the Switch.

Reboot

Clicking on Administration, then Reboot on the menu has the same effect as power cycling the unit. No configuration information will be lost. Reboot the Switch if you are experiencing problems and you want to re-establish your Internet connection.

Any network users that are currently accessing the Internet will have their access interrupted while the reboot takes place, and they may need to restart their computers when the reboot has completed and the Switch is operational again.

2226 PLUS specifications

The 3Com 2226 PLUS is a robust network switch designed to meet the increasing demands of modern networking environments. Its ability to provide reliable connectivity and support for various technologies makes it an ideal choice for small to medium-sized businesses. This switch features 24 10/100 Mbps Ethernet ports, which allow for fast and efficient data transfer, enabling businesses to enhance their network performance significantly.

One of the standout technologies employed in the 3Com 2226 PLUS is its support for auto-negotiation. This feature automatically detects the speed and duplex capabilities of connected devices, ensuring optimal performance and minimizing configuration errors. This capability simplifies network management, allowing IT professionals to focus on other critical tasks rather than troubleshooting connectivity issues.

In addition to its impressive port offerings, the 3Com 2226 PLUS incorporates a range of Layer 2 switching features. These include support for Virtual LANs (VLANs), which enable businesses to segment their networks for improved security and efficiency. By implementing VLANs, organizations can isolate sensitive data traffic from less secure networks, enhancing overall data protection.

The switch also supports Spanning Tree Protocol (STP), which helps prevent loops in network topology. This is crucial in environments with multiple switches, as it maintains a stable network while ensuring redundancy. If a primary link fails, STP allows for a backup path to be automatically activated, ensuring minimal disruption in connectivity.

Power over Ethernet (PoE) capabilities are another significant feature of the 3Com 2226 PLUS. This technology allows the switch to deliver power to connected devices, such as IP cameras and VoIP phones, eliminating the need for additional power supplies and reducing cable clutter.

In terms of management, the 3Com 2226 PLUS supports both simple web-based configuration and SNMP (Simple Network Management Protocol), providing network administrators with flexibility in how they manage their network infrastructure.

Built with reliability in mind, the switch comes equipped with features like store-and-forward switching, error checking, and a sturdy design suitable for deployment in various environments.

Overall, the 3Com 2226 PLUS combines essential features and advanced networking technologies, making it a versatile and dependable solution for businesses looking to upgrade or establish their network infrastructure.
