• Inspect the switch for any physical damage. If damage is found, contact your vendor immediately.

2.2 Стойкага орнотуу

The EX2200-24P-4G switch is designed for standard 19-inch rack mounting. Use the provided rack-mount brackets and screws to secure the switch in the rack. Ensure adequate ventilation space around the unit.

2.3 Кубат туташтыруу

1. Connect the provided AC power cord to the power inlet on the rear panel of the switch.
2. Электр шнурунун экинчи учун жерге туташтырылган электр розеткасына сайыңыз.
3. Verify that the system status LED on the front panel illuminates, indicating power is supplied.

2.4 Initial Configuration (Console Access)

For initial configuration, connect a console cable (RJ-45 to DB-9 or USB-to-serial adapter) from your management workstation to the console port on the front panel of the switch. Use a terminal emulation program (e.g., PuTTY, Tera Term) with the following settings:

• Берүү ылдамдыгы: 9600
• Маалымат биттери: 8
• Паритет: Жок
• Токтоочу биттер: 1
• Агымды башкаруу: Жок

Once connected, you can access the command-line interface (CLI) to perform basic setup, including IP address assignment, user accounts, and network settings.

3. Иштөө нускамалары

3.1 Тармактык түзүлүштөрдү туташтыруу

Connect Ethernet cables from your network devices (computers, servers, IP cameras, access points) to the RJ-45 ports (1-24) on the front panel of the switch. The switch automatically detects the speed and duplex mode of the connected device.

3.2 Ethernet Plus аркылуу кубаттоо (PoE+)

The EX2200-24P-4G supports PoE+ (802.3at) on all 24 access ports. When a PoE-compatible device is connected, the switch automatically detects its power requirements and supplies power over the Ethernet cable, eliminating the need for separate power adapters for these devices.

• Ensure the connected device is PoE/PoE+ compliant.
• Monitor the PoE status LEDs for each port to confirm power delivery.

3.3 SFP Uplink Ports

The four SFP ports (25-28) are used for high-speed uplink connections to other network devices such as core switches or routers. Insert compatible SFP transceivers (fiber or copper) into these slots and connect appropriate cables.

3.4 LED көрсөткүчтөрү

The front panel features various LEDs to indicate the operational status of the switch and its ports:

• SYS LED: Indicates overall system status (e.g., green for normal operation, amber for fault).
• ALM LED: Indicates alarm conditions.
• PoE LED: Indicates PoE status.
• Порт диоддору: Each RJ-45 and SFP port has LEDs indicating link status and activity.

Refer to the official Juniper documentation for a detailed explanation of each LED state.
