1. Introduction
The MikroTik RB260GS (CSS106-5G-1S) is a compact Small Office/Home Office (SOHO) switch designed for efficient network management. It features five Gigabit Ethernet ports and one SFP (Small Form-Factor Pluggable) cage, powered by an Atheros Switch Chip. This device operates on SwOS, an operating system specifically developed by MikroTik for its switch products, offering a range of managed switch functionalities via a web browser interface. A US Power Adapter is included with the unit.
2. Hardware Features
The RB260GS switch is housed in a durable plastic case and provides essential connectivity options for small network environments.
- Ethernet Ports: Five 10/100/1000 Mbps Gigabit Ethernet ports for high-speed wired connections.
- SFP Cage: One SFP cage for fiber optic connectivity, compatible with MikroTik SFP modules such as S-85DLC05D, S-31DLC20D, and S-3553LC20D (modules not included).
- Power Input: Supports Passive PoE (Power over Ethernet) on the first Ethernet port, with an input voltage range of 11-30V. A standard US power adapter is also included.
- Dimensions: Compact design measuring approximately 113x139x28mm.

3. Setup
- Power Connection: Connect the included US power adapter to the device's power jack, or use a Passive PoE injector (not included) with the first Ethernet port.
- Network Connections: Connect your network devices (computers, servers, other switches) to the Gigabit Ethernet ports using standard Ethernet cables.
- SFP Module (Optional): If fiber optic connectivity is desired, insert a compatible SFP module into the SFP cage and connect the appropriate fiber optic cable.
- Initial Access: To access the SwOS configuration interface, connect a computer directly to one of the switch's Ethernet ports. Configure your computer's network adapter to use a static IP address within the 192.168.88.x range (e.g., 192.168.88.2 with subnet mask 255.255.255.0). Then, open a web browser and navigate to the default IP address of the switch, typically http://192.168.88.1.
4. Operating
Once powered on and connected, the RB260GS functions as a layer 2 network switch, forwarding Ethernet frames between connected devices. For basic operation, no further configuration is required. For advanced features and network management, refer to the Configuration section.
5. Configuration (SwOS)
The RB260GS is managed by MikroTik's SwOS, which provides a user-friendly web-based interface for configuration. Access the interface via a web browser using the switch's IP address (default: 192.168.88.1).
Key SwOS Features:
- Port-to-Port Forwarding: Configure specific forwarding rules between switch ports.
- MAC Filter: Apply MAC address-based filtering to control network access.
- VLAN Configuration: Set up Virtual Local Area Networks (VLANs) for network segmentation and traffic isolation.
- Traffic Mirroring: Mirror traffic from one port to another for monitoring and analysis.
- Bandwidth Limitation: Apply rate limits to control bandwidth usage on individual ports.
- MAC and IP Header Fields: Adjust certain MAC and IP header fields for specialized network requirements.
Refer to the official MikroTik SwOS documentation for detailed instructions on configuring these features.
6. Maintenance
- Cleaning: Keep the device clean and free from dust. Use a soft, dry cloth for cleaning. Avoid liquid cleaners.
- Ventilation: Ensure proper airflow around the device to prevent overheating. Do not block ventilation slots.
- Firmware Updates: Regularly check the MikroTik website for firmware updates to ensure optimal performance and security.
7. Troubleshooting
- No Power: Verify the power adapter is securely connected to both the device and a working power outlet. If using PoE, ensure the PoE injector is active and compatible.
- No Network Connectivity: Check all Ethernet cables for secure connections. Ensure connected devices are powered on and configured correctly. Verify the switch's status indicators.
- Cannot Access Web Interface: Confirm your computer's IP address is in the same subnet as the switch (e.g., 192.168.88.x). Try clearing your browser's cache or using a different browser. If issues persist, a factory reset may be necessary (refer to MikroTik documentation for reset procedures).
- Slow Performance: Check for excessive network traffic or potential loops. Ensure all cables are in good condition. Consider reviewing bandwidth limitation settings in SwOS.
