It features Power over Ethernet Plus (PoE+) capabilities on all 24 access ports, providing power to connected devices such as IP phones, wireless access points, and video surveillance cameras. 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. Konfigurazioa eta instalazioa

2.1 Desontziratzea eta ikuskatzea

• Carefully unpack the switch and its accessories from the shipping carton.
• Egiaztatu ontziratze-zerrendan zerrendatutako osagai guztiak daudela.
• Inspect the switch for any physical damage. If damage is found, contact your vendor immediately.

2.2 Rack-en muntaketa

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 Energia-konexioa

1. Connect the provided AC power cord to the power inlet on the rear panel of the switch.
2. Entxufatu korronte-kablearen beste muturra lurreko hartune elektriko batean.
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:

• Baud-tasa: 9600
• Datu-bitak: 8
• Parekidetasuna: bat ere ez
• Stop Bits: 1
• Emaria kontrola: bat ere ez

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

3. Funtzionamendu-argibideak

3.1 Sareko gailuak konektatzea

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 bidezko energia (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 adierazleak

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

• SYS LED: Sistemaren egoera orokorra adierazten du (adibidez, berdea funtzionamendu normala bada, anbarra matxura bada).
• ALM LED: Indicates alarm conditions.
• PoE LED: Indicates PoE status.
• Portuko LEDak: 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.

4. Mantentzea

4.1 Garbiketa

Regularly clean the exterior of the switch with a soft, dry, lint-free cloth. Do not use liquid or aerosol cleaners directly on the unit. Ensure ventilation openings are free from dust and obstructions.

4.2 Firmware eguneraketak

Periodically check the Juniper Networks support website for the latest firmware updates. Keeping the firmware up-to-date ensures optimal performance, security, and access to new features. Follow the instructions provided with the firmware update package carefully.

4.3 Ingurumen-gogoetak

Ensure the switch operates within its specified environmental limits (temperature, humidity). Maintain proper airflow around the device to prevent overheating. Avoid placing the switch in direct sunlight or near heat sources.

5. Arazoak

5.1 Potentziarik gabe

• Egiaztatu elikatze-kablea ondo konektatuta dagoela bai etengailura bai entxufera.
• Egiaztatu entxufea beste gailu batekin funtzionatzen duela ziurtatzeko.
• Ensure the power supply unit (if external) is properly connected and functioning.

5.2 Ez dago loturarik portuan

• Check the Ethernet cable for damage and ensure it is securely plugged into both the switch port and the connected device.
• Ziurtatu konektatutako gailua piztuta dagoela eta behar bezala funtzionatzen duela.
• Try a different port on the switch or a different Ethernet cable.
• Check the port configuration on the switch (e.g., speed, duplex settings).

5.3 PoE gailuak ez du energia jasotzen

• Ensure the connected device is PoE/PoE+ compliant.
• Egiaztatu ataka zehatzaren PoE egoeraren LEDa.
• Verify that the switch's total PoE power budget is not exceeded.
• Saiatu gailua beste PoE ataka batera konektatzen.

5.4 Sarearen konexio arazoak

• Egiaztatu IP helbidearen konfigurazioa switch-ean eta konektatutako gailuetan.
• Egiaztatu sarean IP helbideen gatazkak dauden.
• Ensure proper routing is configured if devices are on different subnets.
• Consult the Juniper Networks documentation for advanced troubleshooting steps.
