   • Cổng SFP: Insert SFP transceivers (if required) into the two SFP ports and connect fiber optic cables for uplink or high-speed connections.
3. Console Connection (Initial Configuration): For initial configuration and management, connect a serial cable from your management workstation to the CON (console) port on the switch. Alternatively, a Mini-USB console port is also available.

4. Hướng dẫn vận hành

4.1. Bật nguồn

Once the power cable is connected, the switch will automatically power on. The boot process for the Junos OS may take several minutes.

4.2. Đèn báo LED

Monitor the front panel LEDs for operational status:

• SYS (Hệ thống): Indicates the overall system status. Typically solid green for normal operation.
• Tốc độ (SPD): Indicates the link speed of the connected port.
• ALM (Báo động): Indicates an alarm condition. Refer to the Junos OS documentation for specific alarm codes and troubleshooting.
• DX (Duplex): Indicates the duplex mode of the connected port.
• CON (Console): Indicates activity on the console port.
• EN (Kích hoạt): Chỉ báo trạng thái.
• PoE (Cấp nguồn qua Ethernet): If applicable, indicates PoE status for ports. (Note: This model does not explicitly list PoE as a feature, but the LED is present).

4.3. Cấu hình

The Juniper EX2200-C-12T-2G switch is managed using the Junos Operating System via a Command Line Interface (CLI). Access the CLI through the console port or via SSH after initial network configuration. Refer to the official Juniper Networks Junos OS documentation for detailed configuration procedures, including VLAN setup, routing protocols, and security settings.
