Additionally, it includes four SFP (Small Form-Factor Pluggable) Gigabit Ethernet uplink ports for flexible network connectivity.

This switch is engineered to deliver reliable, secure, and energy-efficient network access, making it suitable for various business environments requiring robust connectivity and power delivery over Ethernet.

This image displays the front panel of the Juniper EX2200-24P-4G switch. It features 24 Gigabit Ethernet ports with PoE+ capabilities, arranged in two rows of twelve. To the right, there are four SFP (Small Form-Factor Pluggable) Gigabit Ethernet uplink ports, along with LED indicators for system status and port activity.

2. सेटअप आणि स्थापना

2.1 अनपॅकिंग आणि तपासणी

• Carefully unpack the switch and its accessories from the shipping carton.
• पॅकिंग यादीमध्ये सूचीबद्ध केलेले सर्व घटक उपस्थित आहेत याची पडताळणी करा.
• Inspect the switch for any physical damage. If damage is found, contact your vendor immediately.

2.2 रॅक माउंटिंग

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 वीज जोडणी

1. Connect the provided AC power cord to the power inlet on the rear panel of the switch.
2. पॉवर कॉर्डचे दुसरे टोक ग्राउंड केलेल्या इलेक्ट्रिकल आउटलेटमध्ये प्लग करा.
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:

• बॉड दर: 9600
• डेटा बिट्स: 8
• समता: काहीही नाही
• बिट्स थांबवा: 1
• प्रवाह नियंत्रण: काहीही नाही

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

3. ऑपरेटिंग सूचना

3.1 Connecting Network Devices

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 Power over Ethernet Plus (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 एलईडी निर्देशक

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).
• एएलएम एलईडी: Indicates alarm conditions.
• PoE LED: Indicates PoE status.
• पोर्ट LEDs: 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.
