- Connect the console cable (RJ-45 end) to the CONSOLE port on the front panel of the SRX300.
- Connect the other end (DB-9 or USB adapter) to your management workstation.
- Configurez votre logiciel d'émulation de terminal (par exemple, PuTTY, Tera Term) avec les paramètres suivants : 9 600 bauds, 8 bits de données, pas de parité, 1 bit d'arrêt, pas de contrôle de flux.
- Power on the device. You should see boot messages in your terminal window.
- Follow the on-screen prompts for initial configuration, including setting the root password and basic network parameters.
- Connectez les câbles réseau : Connect your network devices (e.g., modem, switches, computers) to the appropriate Ethernet (ge-0/0/0 to ge-0/0/5) or SFP (ge-0/0/6, ge-0/0/7) ports as required by your network design.
- Vérifiez la connectivité : Once initial configuration is complete, verify network connectivity and access to the device.
6. Operating the SRX300
The SRX300 Services Gateway operates on Juniper's Junos OS. Configuration and management are primarily performed via the command-line interface (CLI) through the console port or SSH, or via the J-Web graphical user interface (GUI).
- Accessing the CLI: Use a terminal emulator connected to the console port or an SSH client to connect to the device's IP address.
- J-Web Interface utilisateur graphique : If enabled, access the J-Web interface by entering the device's IP address into a web navigateur.
- État de la surveillance : Regularly check the front panel LEDs (PWR, ALARM, STAT, HA) for operational status. Consult the Junos OS documentation for detailed LED behavior.
- Basic Commands (CLI examples) :
show interfaces terse: Displays a summary of network interface status.show system alarm: Shows current system alarms.show security flow session: Displays active network sessions.
For detailed configuration and advanced features, refer to the official Juniper Networks Junos OS documentation.
