3.4 Connexion réseau initiale
Connect an Ethernet cable from your computer to one of the Gigabit Ethernet ports (e.g., ge-0/0/0) on the SRX220H-POE for initial configuration. Alternatively, use the console port with a console cable and terminal emulation software.
4. Utilisation de l'appareil
4.1 Mise sous et hors tension
To power on the device, connect the power cord. The device will automatically start. To power off, disconnect the power cord from the electrical outlet. It is recommended to gracefully shut down the system via the command-line interface (CLI) before disconnecting power, if possible.
4.2 Configuration de base
Access the device's CLI via the console port or an Ethernet management interface. Default login credentials are typically racine with no password (for initial setup). Refer to the Juniper Networks documentation for detailed configuration guides for Junos OS.
- Setting IP Address: Configure the management interface with a static IP address.
- Comptes utilisateurs : Create new user accounts with strong passwords and delete or disable default accounts.
- Politiques de sécurité : Implement appropriate security policies for your network environment.
4.3 Alimentation par Ethernet (PoE)
The SRX220H-POE ports support Power over Ethernet, allowing compatible devices (e.g., IP phones, wireless access points) to receive power and data over a single Ethernet cable. Ensure connected devices are PoE-compatible and do not exceed the total power budget of the SRX220H-POE.
