3. Installation

Follow these steps for proper installation of your BDCOM S2900-24T4X-2AC switch.

3.1 Site Preparation

• Ensure the installation site is clean, dry, and well-ventilated.
• Maintain an ambient temperature between 0°C and 50°C (32°F and 122°F).
• Avoid direct sunlight, heat sources, and excessive dust.
• Ensure adequate space around the switch for proper airflow, especially at the sides where ventilation is located.

3.2 Rack Mounting

The switch is designed for standard 19-inch rack-mounted installation (1U height).

1. Attach the provided rack-mount brackets to the sides of the switch using the included screws.
2. Align the switch with the rack posts and secure it using appropriate rack screws.
3. Ensure the switch is level and securely fastened in the rack.

3.3 Power Connection

1. Ensure the power switch on the rear panel is in the OFF position.
2. Connect one end of the AC power cord to the power input on the rear panel of the switch.
3. Connect the other end of the AC power cord to a grounded power outlet (100-240 VAC, 50/60 Hz).
4. Flip the power switch to the ON position. The Power (PWR) LED on the front panel should illuminate.

3.4 Network Connections

• GE TX Ports: Connect standard RJ45 Ethernet cables from your network devices (servers, workstations, other switches) to the GE TX ports (1-24).
• 10GE/GE SFP+ Ports: Insert compatible SFP+ transceivers into the SFP+ slots (TE1-TE4). Connect fiber optic cables from other network devices or uplinks to these transceivers. Ensure the transceivers and cables match the required speed (1G or 10G).
• Console Port: For initial configuration and management, connect a console cable (RJ45 to DB9 or USB) from your management workstation to the console port.

4. Initial Configuration

The BDCOM S2900-24T4X-2AC switch can be configured via its Command Line Interface (CLI) through the console port or via a web-based Graphical User Interface (GUI).

4.1 Console Access (CLI)

1. Connect your computer to the switch's console port using a console cable.
2. Open a terminal emulation program (e.g., PuTTY, Tera Term) on your computer.
3. Configure the serial port settings:
   • Baud Rate: 9600
   • Data Bits: 8
   • Parity: None
   • Stop Bits: 1
   • Flow Control: None
4. Power on the switch. The boot-up messages will appear in the terminal window.
5. Log in using the default credentials (refer to the official BDCOM documentation for default username and password).
6. Begin configuring the switch according to your network requirements. The command structure is similar to Cisco IOS.

4.2 Web-based Management (GUI)

Once the switch has an IP address configured (either manually via CLI or via DHCP), you can access its web interface.

1. Ensure your management computer is on the same network segment as the switch.
2. Open a web browser and enter the switch's IP address.
3. Log in using the appropriate credentials.
4. The GUI provides a user-friendly interface for configuring various switch functions. Note that the included PKI certificate may be expired, requiring generation of a new one for secure access.

For detailed command references and advanced configuration, please consult the official BDCOM S2900 series documentation.

5. Operating Instructions

The BDCOM S2900-24T4X-2AC switch operates automatically once configured. Here are general operational guidelines:

• Power On/Off: Use the power switch on the rear panel. Always ensure proper shutdown procedures if available through CLI/GUI before powering off.
• LED Indicators: Monitor the front panel LEDs for operational status:
  • PWR (Power): Solid green indicates the switch is powered on.
  • SYS (System): Indicates system status (e.g., solid green for normal operation, blinking for activity or errors). Refer to the full manual for specific patterns.
  • Port LEDs: Indicate link status and activity for each GE and SFP+ port.
• Network Connectivity: Ensure all connected devices are properly cabled and configured for network access.
• Layer-3 Lite Functionality: The switch supports basic Layer-3 routing capabilities. Configure VLANs, IP interfaces, and static routes as needed for inter-VLAN routing and network segmentation.
• Link Aggregation (LACP): For increased bandwidth and redundancy, configure Link Aggregation Control Protocol (LACP) on multiple ports to form a single logical link (port channel). Ensure a lower value for the 'agg-period' parameter if configuring LACP.

6. Maintenance

Regular maintenance helps ensure the longevity and optimal performance of your switch.

• Cleaning: Periodically clean the exterior of the switch with a soft, dry cloth. Do not use liquid or aerosol cleaners. Ensure ventilation openings are free from dust and obstructions.
• Firmware Updates: Check the BDCOM official website for the latest firmware updates. Applying updates can improve performance, add features, and fix bugs. Follow the provided instructions carefully during firmware upgrades.
• Configuration Backup: Regularly back up your switch configuration to an external storage device. This allows for quick restoration in case of a device reset or failure.
• Environmental Monitoring: Ensure the operating environment remains within specified temperature and humidity ranges.

7. Troubleshooting

This section provides solutions to common issues. For more complex problems, contact technical support.

7.1 Power Issues

• No Power:
  • Verify the power cord is securely connected to both the switch and the power outlet.
  • Ensure the power switch on the rear panel is in the ON position.
  • Check the power outlet with another device to confirm it is functional.

7.2 Network Connectivity Issues

• No Link on a Port:
  • Check the Ethernet or fiber cable connection. Ensure it is securely plugged into both the switch port and the connected device.
  • Verify the cable is not damaged. Try a different cable.
  • Ensure the connected device is powered on and functioning correctly.
  • Check the port status LEDs on the switch. If the LED is off, there might be no link.
  • For SFP+ ports, ensure the transceiver is correctly seated and compatible. The switch can be particular about transceivers.
• Slow Network Performance:
  • Check for network congestion.
  • Verify duplex and speed settings on the switch port and connected device.
  • Ensure cables are appropriate for the speed (e.g., Cat5e/6 for Gigabit Ethernet).

7.3 Management Access Issues

• Cannot Access CLI via Console:
  • Verify the console cable connection.
  • Check the serial port settings in your terminal emulation program (Baud Rate, Data Bits, Parity, Stop Bits, Flow Control).
  • Ensure the correct COM port is selected.
• Cannot Access GUI via Web Browser:
  • Verify the switch has an IP address and your computer can reach it (ping the IP address).
  • Ensure your web browser is not blocking the connection due to certificate warnings (the default certificate may be expired).
  • Clear browser cache or try a different browser.
