3.6 Akses Konfigurasi Awal

For initial configuration, connect a console cable from your management workstation to the console port on the switch. Use a terminal emulation program (e.g., PuTTY, Tera Term) with appropriate settings (typically 9600 baud, 8 data bits, no parity, 1 stop bit, no flow control) to access the command-line interface (CLI).

4. Operasi

4.1 Hidupkan/Mati Kuasa

Once connected to a power source, the switch will automatically power on. There is no physical power button. To power off, disconnect the power cord. For proper shutdown, it is recommended to save configurations before disconnecting power.

4.2 Penunjuk LED

The front panel of the switch features various LEDs to indicate system status and port activity:

• LED sistem: Indicates overall system health (e.g., green for normal operation, amber for issues).
• LED RPS: Indicates the status of the Redundant Power System (if installed).
• Stack LED: Indicates the status of the FlexStack connection.
• LED Status Pelabuhan: Each Ethernet port has an LED to indicate link status (on/off) and activity (blinking). Green typically indicates a 1000 Mbps link, amber for 10/100 Mbps.
• LED PoE: Indicates Power over Ethernet status for the respective port.

4.3 Power over Ethernet Plus (PoE+)

The switch supports PoE+ (802.3at) on all 48 Ethernet ports, providing up to 30W of power per port to compatible devices such as IP phones, wireless access points, and surveillance cameras. Ensure connected devices are PoE+ compliant for optimal performance.
