2. Ethernet Network Ports: You can connect your computer to any standard Ethernet port on the switch. If your computer is set to obtain an IP address automatically (DHCP), it will often self-assign a link-local address in the 169.254.x.x range. The default IP for these ports is usually 169.254.100.100. Alternatively, you can configure your computer with a static IP address within the 169.254.0.0/16 subnet, such as 169.254.100.201.
3. Console Port (CLI): For those who prefer command-line interfaces, the M4250 also offers a console port (either USB-C or RJ-45 RS232). You’ll need a console cable and a terminal emulation program (like PuTTY) on your computer.

Accessing the AV GUI

Once connected, launch a web browser and enter the appropriate default IP address (e.g., http://192.168.0.239 for the OOB port). You’ll be presented with a login page offering options for the “AV UI” or “Main UI.” For simplified AV configuration, always choose the AV UI.

For your first login:

• Username: admin
• Password: Leave it blank (you’ll be prompted to create a new password immediately for security).

After setting your new password, you’ll enter the intuitive AV GUI.

Applying AV Profiles: Instant Configuration

The true power of the Netgear M4250’s AV GUI lies in its pre-configured profiles.
