2.3 Packungsinhalt
The standard package for the CRS328-24P-4S+RM typically includes:
- MikroTik CRS328-24P-4S+RM Cloud Router Switch unit
- Power cable (IEC C13)
- Rackmount ears and screws
3. Einrichtung
3.1 Physische Installation
The CRS328-24P-4S+RM is designed for 1U rackmount installation. Follow these steps:
- Attach the included rackmount ears to the sides of the device using the provided screws.
- Secure the device into a standard 19-inch server rack using appropriate rack screws. Ensure adequate ventilation around the unit.
- Connect your network cables to the desired Gigabit Ethernet ports and SFP+ ports.
3.2 Einschalten
Connect the included power cable to the AC input on the rear of the device and then to a compatible power outlet (100-240 V AC). The device will power on automatically.
3.3 Zugriff auf die Erstkonfiguration
The device can be configured via several methods:
- WinBox Utility: Download the WinBox utility from the official MikroTik website. Connect your computer to any Ethernet port on the switch. WinBox can discover the device and allow graphical configuration.
- Web Schnittstelle (WebFig): Öffnen Sie ein web browser and navigate to the device's default IP address (typically 192.168.88.1).
- Serial Console: For advanced users, a serial console port is available for command-line interface (CLI) access.
Important: For security, it is highly recommended to change the default administrator password immediately after initial access.
4. Bedienungsanleitung
4.1 Dual Boot Feature
The CRS328-24P-4S+RM supports dual boot, allowing you to choose between MikroTik's RouterOS (a full-featured routing operating system) and SwOS (a simpler, switch-optimized operating system). The desired OS can be selected during boot-up or configured via the management interface.
4.2 Ethernet Ports and PoE
The 24 Gigabit Ethernet ports support various Power over Ethernet (PoE) standards:
- Passives PoE: Provides power directly to compatible devices.
- Niedrige Lautstärketage PoE: For specific low-voltage-Anwendungen.
- 802.3af/at (PoE/PoE+): Auto-sensing for standard compliant devices.
PoE-Out is passed over mode B pins (4,5+)(7,8-). Each port can deliver up to 30 W of power, with a total guaranteed power budget of 450 W for connected PoE devices (distributed as 3x150 W per every 8 Ethernet ports).
4.3 SFP+-Anschlüsse
The four SFP+ ports provide 10 Gigabit per second connectivity. These ports require compatible SFP+ modules (not included) for either optical fiber or direct attach copper (DAC) Ethernet connections. Ensure modules are properly seated and locked into place.
4.4 Management-Schnittstellen
The device offers flexible management options:
- WinBox: A dedicated Windows application for graphical configuration.
- WebFeige: A web-based graphical user interface accessible via a standard web Browser.
- CLI (Befehlszeilenschnittstelle): Accessible via SSH, Telnet, or serial console for advanced configuration and scripting.
Refer to the MikroTik documentation for detailed instructions on configuring specific network functions such as VLANs, routing, firewall rules, and QoS.
5. Wartung
5.1 Firmware-Updates
Regularly updating the device's firmware (RouterOS or SwOS) is crucial for security, stability, and access to new features. MikroTik provides updates through its official website. Always back up your configuration before performing a firmware upgrade.
- Download the latest firmware package for your device model from the MikroTik webWebsite.
- Upload the package to the device using WinBox, WebFig, or FTP.
- Reboot the device to apply the update.
5.2 Reinigung
To maintain optimal performance, periodically clean the device. Use a soft, dry cloth to wipe the exterior. Ensure the device is powered off and disconnected from the power source before cleaning. Avoid using liquid cleaners or solvents.
6. Fehlerbehebung
If you encounter issues with your CRS328-24P-4S+RM, consider the following common troubleshooting steps:
- Kein Strom: Verify the power cable is securely connected and the power outlet is functional. Check the power supply unit.
- Keine Netzwerkverbindung: Check Ethernet cable connections. Verify port status LEDs. Ensure correct IP configuration on connected devices and the switch.
- PoE-Geräte schalten sich nicht ein: Confirm the connected device is PoE compatible. Check PoE settings on the switch ports. Ensure the total power consumption does not exceed the switch's PoE budget.
- Langsame Leistung: Check for network loops, excessive broadcast traffic, or misconfigured VLANs. Monitor CPU and memory usage via the management interface.
- Access Issues (WinBox/WebFig): Ensure your computer is on the same subnet as the switch. Temporarily disable firewalls on your computer. Try accessing via serial console if network access is completely lost.
For more detailed troubleshooting guides and solutions, refer to the official MikroTik documentation and community forums.
