5. Pengaturan

5.1. Pemasangan Rak

1. Attach the provided rack-mount brackets to the sides of the switch using the screws supplied in the rack-mount kit.
2. Align the switch with the rack posts and secure it using appropriate rack screws. Ensure the switch is level and firmly seated.

5.2. Menghubungkan Daya

1. Hubungkan salah satu ujung kabel daya ke soket daya AC di panel belakang sakelar.
2. Hubungkan ujung kabel daya lainnya ke stopkontak AC yang memiliki ground.
3. The switch features a redundant internal power supply for enhanced reliability.

5.3. Connecting Network Devices

1. Connect Ethernet cables from your network devices (computers, IP phones, wireless access points) to the 48 Gigabit Ethernet ports on the front panel.
2. For devices requiring Power over Ethernet (PoE+), ensure they are compatible and connect them to any of the 48 ports. The switch will automatically detect and provide power.
3. For uplink connections to other switches or routers, use appropriate Ethernet cables.

5.4. Konfigurasi Awal (Opsional)

For initial configuration or advanced management, connect a console cable (not typically included) to the console port (usually RJ-45) on the front or rear panel and connect it to a computer. Use a terminal emulation program to access the command-line interface (CLI).

6. Mengoperasikan Sakelar

6.1. Menghidupkan/Mematikan

• Nyalakan: Once the power cord is connected, the switch will typically power on automatically. Observe the system LEDs.
• Matikan: To power off, disconnect the power cord from the AC outlet. For controlled shutdown, it is recommended to gracefully shut down the operating system via the CLI if possible, before disconnecting power.

6.2. Memahami Indikator LED

The front panel LEDs provide critical status information:

• ALM (Alarm): Indicates system alarms or critical errors. Refer to the CLI or system logs for details.
• SYS (Sistem): Menunjukkan status sistem secara keseluruhan. Biasanya berwarna hijau solid untuk pengoperasian normal.
• MST (Guru): Indicates if the switch is operating as the master in a Virtual Chassis configuration.
• LED Pelabuhan: Setiap port Ethernet memiliki LED yang menunjukkan status dan aktivitas tautan.

7. Pemeliharaan

• Pembersihan: Periodically clean the exterior of the switch with a soft, dry cloth. Do not use liquid or aerosol cleaners. Ensure ventilation openings are free of dust and debris.
• Pembaruan Firmware: Regularly check the Juniper Networks support website for firmware updates. Applying updates can improve performance, add features, and address security vulnerabilities. Follow the manufacturer's instructions for firmware upgrade procedures.
• Pemantauan Lingkungan: Pastikan lingkungan pengoperasian tetap berada dalam kisaran suhu dan kelembapan yang ditentukan untuk memperpanjang umur perangkat.
