The front panel includes:

• 20x 1G Ethernet Ports: Standard RJ45 ports for Gigabit Ethernet connectivity.
• 4x Combo SFP+/1G Ethernet Ports: These ports can function as either 10 Gigabit SFP+ fiber ports or 1 Gigabit RJ45 Ethernet ports. Only one mode can be active at a time per combo port.
• 2x 40G QSFP+ Ports: High-speed Quad Small Form-Factor Pluggable Plus ports for 40 Gigabit fiber connections.
• LED Indicators: Status LEDs for power, activity, and other operational states.

4.2 Rear Panel

The rear panel includes:

• 2x AC Power Inputs: Redundant power inputs (POWER1, POWER2) for increased reliability.
• Grounding Screw: For connecting to an earth ground.

5. Setup

5.1 Rack Mounting

To install the switch in a standard 1U server rack:

1. Attach the two rackmount ears to the sides of the switch using the provided screws.
2. Secure the switch into the rack using appropriate rack screws (not included).

5.2 Desktop Placement

For desktop use, attach the included rubber feet to the bottom of the switch to prevent scratching surfaces and provide stability.

5.3 Power Connection

Connect one or both of the provided IEC power cables to the AC power inputs on the rear panel of the switch and then to a suitable power source. The device supports redundant power for continuous operation.

5.4 Initial Configuration

The device comes pre-installed with RouterOS v7. For initial configuration:

1. Connect a computer to any of the Gigabit Ethernet ports.
2. Open a web browser and navigate to the default IP address (usually 192.168.88.1).
3. Log in using the default credentials (username: admin, no password). It is highly recommended to set a strong password immediately.
4. Alternatively, use MikroTik's WinBox utility for a graphical configuration interface or connect via serial console for command-line access.

6. Operating Instructions

The CRS326-4C+20G+2Q+RM operates on MikroTik's RouterOS v7, offering extensive networking features. Key operational aspects include:

• Port Management: Configure individual port settings, including speed, duplex, and flow control.
• VLAN Configuration: Implement Virtual Local Area Networks (VLANs) for network segmentation and traffic management. Refer to the RouterOS documentation for detailed VLAN setup procedures.
• Link Aggregation (LACP): Combine multiple physical links into a single logical link for increased bandwidth and redundancy.
• Routing and Firewall: Utilize RouterOS capabilities for static and dynamic routing, as well as firewall rules to secure your network.
• Monitoring: Monitor port status, traffic statistics, and system resources through the web interface or WinBox.

For detailed configuration guides and advanced features, consult the official MikroTik RouterOS documentation available on their website.

7. Maintenance

Regular maintenance ensures optimal performance and longevity of your device:

• Firmware Updates: Regularly check for and install the latest RouterOS firmware updates to benefit from new features, bug fixes, and security enhancements.
• Cleaning: Keep the device and its ventilation openings free from dust and debris. Use a soft, dry cloth for cleaning. Do not use liquid cleaners.
• Environmental Control: Ensure the operating environment maintains stable temperature and humidity levels as specified in the product's technical specifications.
• Backup Configuration: Periodically back up your device configuration to prevent data loss in case of unforeseen issues.

8. Troubleshooting

If you encounter issues with your CRS326-4C+20G+2Q+RM, consider the following troubleshooting steps:

• No Power: Verify that power cables are securely connected and the power source is active. Check the power LEDs on the device.
• No Connectivity: Ensure Ethernet cables are properly connected to active ports. Check port link/activity LEDs. Verify IP address configuration on connected devices and the switch.
• SFP+/QSFP+ Module Issues: Ensure SFP+/QSFP+ modules are correctly inserted and compatible with the switch and connected devices. Some modules may require specific RouterOS configurations or may not perform optimally with certain cable types or lengths. Refer to MikroTik's compatibility list.
• Slow Performance: Check for network bottlenecks, cable quality, and duplex mismatches. Ensure SFP+/QSFP+ modules are operating at their intended speeds.
• Accessing Web Interface/WinBox: Confirm your computer's IP address is in the same subnet as the switch's management IP. Try resetting the switch to factory defaults if access is completely lost (refer to MikroTik documentation for the reset procedure).
• System Logs: Review the system logs in RouterOS for error messages or warnings that can provide clues to the problem.
