Монтажа на сто:

Place the switch on a flat, stable surface, ensuring adequate ventilation around the device.

5.2 Повезивање напајања

1. Connect the power cord to the AC power connector on the rear of the switch.
2. Укључите други крај кабла за напајање у уземљену утичницу са наизменичном струјом.
3. The system will power on automatically. Observe the System LED for status.

5.3 Повезивање мрежних каблова

• Data Ports (RJ-45): Connect Ethernet cables from your network devices (computers, access points, IP phones) to the 48 UPoE ports on the front panel. These ports provide both data and power.
• Уплинк портови: Install appropriate uplink modules (if not pre-installed) into the modular uplink slots. Connect fiber or copper cables from these uplink ports to your core network or other switches.
• Порт за управљање: For out-of-band management, connect an Ethernet cable from your management workstation to the dedicated management port on the rear panel.

5.4 Приступ почетној конфигурацији

To perform initial configuration, connect a console cable from your computer's serial port (or USB-to-serial adapter) to the USB Mini-B console port on the switch's front panel. Use a terminal emulation program (e.g., PuTTY, Tera Term) with the following settings:

• Брзина преноса: 9600
• Битови података: 8
• Паритет: Нема
• Стоп битови: 1
• Контрола протока: нема

6. Руковање прекидачем

6.1 Укључивање/искључивање

The switch powers on automatically when connected to a power source. To power off, disconnect the power cord. For graceful shutdown, it is recommended to use the command-line interface (CLI) to save configurations before disconnecting power.

6.2 ЛЕД индикатори

The front panel LEDs provide visual status of the switch operation:

• Системска ЛЕД диода: Indicates overall system status (Green: Normal, Amber: Fault).
• RPS LED: Redundant Power System status.
• Статус ЛЕД: General port status.
• Duplex LED: Indicates port duplex mode (e.g., Full, Half).
• ЛЕД за брзину: Indicates port speed (e.g., 1G, 5G).
• ПоЕ ЛЕД: Indicates Power over Ethernet status for UPoE ports.
• Stack LED: Indicates stacking status when multiple switches are connected in a stack.

6.3 Основна конфигурација мреже
