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. Setup u Installazzjoni

2.1 Spakkjar u Spezzjoni

• Carefully unpack the switch and its accessories from the shipping carton.
• Ivverifika li l-komponenti kollha elenkati fil-lista tal-ippakkjar huma preżenti.
• Spezzjona s-swiċċ għal xi ħsara fiżika. Jekk issib ħsara, ikkuntattja lill-bejjiegħ tiegħek immedjatament.

2.2 Immuntar fuq Rack

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 Konnessjoni tal-Enerġija

1. Connect the provided AC power cord to the power inlet on the rear panel of the switch.
2. Ipplaggja t-tarf l-ieħor tal-korda tad-dawl fi żbokk elettriku ertjat.
3. Verify that the system status LED on the front panel illuminates, indicating power is supplied.

2.4 Konfigurazzjoni Inizjali (Aċċess għall-Console)

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:

• Rata Baud: 9600
• Bits tad-Data: 8
• Parità: Xejn
• Waqqaf Bits: 1
• Kontroll tal-Fluss: Xejn

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

3. Istruzzjonijiet Operattivi

3.1 Konnessjoni ta' Apparati tan-Netwerk

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 Indikaturi LED

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

• LED SYS: Indicates overall system status (e.g., green for normal operation, amber for fault).
• LED ALM: Indicates alarm conditions.
• LED PoE: Indicates PoE status.
• LEDs tal-port: 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. Manutenzjoni

4.1 Tindif

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 Aġġornamenti tal-Firmware

Iċċekkja perjodikament l-appoġġ ta' Juniper Networks 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 Konsiderazzjonijiet Ambjentali

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 Issolvi l-problemi

5.1 Ebda Qawwa

• Iċċekkja li l-korda tal-enerġija hija konnessa sew kemm mas-swiċċ kif ukoll mas-sokit tal-enerġija.
• Iċċekkja s-sokit tal-enerġija b'apparat ieħor biex tiżgura li jaħdem.
• Ensure the power supply unit (if external) is properly connected and functioning.

5.2 L-ebda Link fuq il-Port

• Check the Ethernet cable for damage and ensure it is securely plugged into both the switch port and the connected device.
• Ivverifika li l-apparat konness ikun mixgħul u jaħdem sew.
• Try a different port on the switch or a different Ethernet cable.
• Iċċekkja l-konfigurazzjoni tal-port fuq is-swiċċ (eż., il-veloċità, is-settings tad-duplex).

5.3 Apparat PoE Mhux Qed Jirċievi l-Enerġija

• Ensure the connected device is PoE/PoE+ compliant.
• Iċċekkja l-LED tal-istatus tal-PoE għall-port speċifiku.
• Verify that the switch's total PoE power budget is not exceeded.
• Ipprova qabbad l-apparat ma' port PoE differenti.

5.4 Kwistjonijiet ta' Konnettività tan-Netwerk

• Ivverifika l-konfigurazzjoni tal-indirizz IP fuq is-swiċċ u l-apparati konnessi.
