3.5 Початкова конфігурація

For initial configuration, connect a console cable to the console port on the switch and to a computer. Use a terminal emulation program (e.g., PuTTY, Tera Term) with the following settings: 9600 baud, 8 data bits, no parity, 1 stop bit, no flow control. Refer to the Juniper Networks documentation for detailed CLI or web кроки налаштування інтерфейсу.

4. Керування комутатором

4.1 Увімкнення/вимкнення

To power on the switch, flip the power switch on the rear panel to the ON position. The system will initiate its boot sequence. To power off, flip the power switch to the OFF position. For controlled shutdowns, it is recommended to use the appropriate command-line interface (CLI) or web interface commands to prevent data corruption.

4.2 світлодіодні індикатори

The front panel features various LED indicators that provide status information for the system and individual ports.

• Індикатор системи: Indicates overall system status (e.g., power, boot status).
• Світлодіоди портів: Each Ethernet port has LEDs to indicate link status, activity, and PoE status. Refer to the detailed product documentation for specific LED behavior.
• SFP LEDs: Indicate link status and activity for the SFP uplink ports.

4.3 Функціональність порту

The EX2200-48P-4G provides 48 Gigabit Ethernet ports with Power over Ethernet (PoE) capabilities, allowing you to power compatible devices such as IP phones, wireless access points, and surveillance cameras directly through the network cable. The 4 SFP (Small Form-Factor Pluggable) uplink ports support fiber optic or copper connections for high-speed data transmission to other network devices or the core network.

4.4 Інтерфейси управління

The switch can be managed through several interfaces:

• Command-Line Interface (CLI): Accessible via the console port or SSH/Telnet for advanced configuration and monitoring.
• Web-Based Interface (Web інтерфейс користувача): Provides a graphical interface for easier management and monitoring, accessible via a web браузер.
• SNMP: Supports Simple Network Management Protocol for integration with network management systems.

5. Технічне обслуговування
