4. Opstelling

4.1. Uitpak en inspeksie

Carefully remove the switch from its packaging. Inspect the device for any signs of physical damage. Report any damage to your supplier immediately.

4.2. Rakmontering

The EX3400-48P is designed for standard 19-inch rack installation. Use the provided rack-mount brackets and screws to secure the switch in the rack. Ensure adequate space for airflow around the unit.

4.3. Kragverbinding

1. Maak seker dat die kragskakelaar op die agterpaneel in die AF-posisie is.
2. Connect the power cord to the power supply unit on the rear of the switch.
3. Steek die ander kant van die kragkabel in 'n geaarde WS-kragaansluiting.
4. Flip the power switch to the ON position. The system status LED should illuminate.

4.4. Aanvanklike konfigurasie

For initial configuration, connect a console cable from your computer to the console port on the rear of the switch. Use a terminal emulation program (e.g., PuTTY, Tera Term) with the following settings:

• Baud tarief: 9600
• Data stukkies: 8
• Pariteit: Geen
• Stop stukkies: 1
• Vloeibeheer: Geen

Follow the on-screen prompts to set up basic network parameters such as IP address, subnet mask, and default gateway.

5. Bedryf

5.1. Skakel aan/af

• Krag aan: After connecting the power cord, press the power switch to the ON position. The switch will perform a power-on self-test (POST).
• Skakel af: To power off, press the power switch to the OFF position. For a controlled shutdown, it is recommended to save the configuration and issue a shutdown command via the command-line interface (CLI) before physically powering off.

5.2. LED-aanwysers

• SYS LED: Dui die algehele stelselstatus aan (bv. groen vir normale werking, oranje vir waarskuwing, rooi vir kritieke fout).
• ALM LED: Dui alarmstatus aan.
• PoE LED: Indicates Power over Ethernet status.
• Poort LED's: Indicate link status and activity for each Ethernet port.

5.3. Netwerkopstelling

The EX3400-48P can be configured via its command-line interface (CLI) or a web-based graphical user interface (GUI) if enabled. Common configurations include:

• VLAN creation and assignment.
• Port security settings.
• Routing protocols.
• Quality of Service (QoS) settings.
• Spanning Tree Protocol (STP) configuration.

Refer to the Juniper Networks documentation for detailed configuration guides specific to Junos OS.
