   • SFP portovi: 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. Uputstvo za upotrebu

4.1. Uključivanje

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. LED indikatori

Pratite LED diode na prednjoj ploči za radni status:

• SYS (Sistem): Indicates the overall system status. Typically solid green for normal operation.
• SPD (Brzina): Indicates the link speed of the connected port.
• ALM (Alarm): 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 (Enable): Indikator statusa.
• PoE (napajanje preko Etherneta): 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. Konfiguracija

The Juniper EX2200-C-12T-2G switch is managed using the Junos Operating System via a Command Line Interface (CLI).
