34CHAPTER 4: CONFIGURING THE SWITCH

To determine the exact IP address that the Switch assigns to itself during auto IP configuration, check the sticker on the base of the Switch. This sticker contains the MAC address and default IP address of the Switch.

To detect its IP information using the automatic configuration process, the Switch goes through the following sequence of steps:

1The Switch tries to configure itself with the default IP address 169.254.x.y, where x and y are converted from the last two bytes of its MAC address.

For example, if the MAC address is

08004E000102, the IP address would be 169.254.1.2. This address is used if the Switch is operating in a standalone mode, or no other switches on the network have this IP address.

The Switch also assigns the subnet mask 255.255.0.0 (default class B mask) to itself.

2If this default IP address is already in use on the network, then the Switch detects this, and increments the last byte of the MAC address by one to generate its IP address.

The IP address would therefore become 169.254.1.3.

3The Switch repeats step 2 until an unused IP address is found.

3Com recommends using automatic IP configuration only for the initial setup. Once you gain access to the console, you should assign an IP address to the Switch (either by using DHCP or assigning a static IP address) to ensure successful communication between the Switch and other network devices.

IP Setup

To set the IP address for the Switch:

1Click Administration, then IP Setting on the menu. The IP Settings screen appears. Follow the IP Setup Wizard to complete the setup.

This wizard can also be used to set system name, location and contact information.

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.
