5. Setup

Follow these steps to properly set up your Cisco UCS C240 M3 server.

5.1 Rack Installation

1. Prepare the Rack: Ensure the rack is stable and has adequate space for a 2U server.
2. Install Rail Kit: Attach the provided rail kit to the rack posts according to the instructions included with the rail kit.
3. Mount the Server: Carefully slide the server onto the installed rails until it clicks into place. Secure the server to the rack using the provided screws.

5.2 Connecting Peripherals

• Power: Connect the power cords from the server's power supply units to separate, grounded power outlets or a power distribution unit (PDU).
• Network: Connect Ethernet cables from the server's network ports to your network switch.
• Console (Optional): For initial setup or direct access, connect a monitor to the VGA port and a keyboard/mouse to the USB ports on the rear panel.

5.3 Initial Power On

1. Ensure all connections are secure.
2. Press the power button on the front panel.
3. Observe the system status LEDs for normal operation.
4. Access the Cisco Integrated Management Controller (IMC) via a web browser using the server's management IP address for further configuration. Refer to the Cisco UCS C-Series Servers Integrated Management Controller GUI Configuration Guide for detailed instructions.

6. Operating the Server

This section covers basic operational procedures for the Cisco UCS C240 M3 server.

6.1 Power On/Off Procedures

• Power On: Press the power button on the front panel. The system will initiate its boot sequence.
• Normal Shutdown: From the operating system, perform a graceful shutdown. Once the OS has shut down, the server will power off automatically.
• Forced Shutdown: In an emergency, press and hold the power button for more than 4 seconds. This should only be used as a last resort to prevent data corruption.

6.2 Accessing Cisco IMC

The Cisco Integrated Management Controller (IMC) provides a web-based interface for server management. To access it:

1. Ensure the server's management port is connected to the network.
2. Obtain the IP address assigned to the IMC (either through DHCP or manual configuration during initial setup).
3. Open a web browser and enter the IMC's IP address.
4. Log in with your credentials.

6.3 Operating System Installation

Operating system installation can be performed via the Cisco IMC's KVM console, virtual media, or by booting from a physical optical drive or USB device connected to the server. Consult your chosen operating system's installation guide for specific steps.

7. Maintenance

Regular maintenance ensures optimal performance and longevity of your server.

7.1 Hot-Swappable Components

The Cisco UCS C240 M3 features hot-swappable components, allowing replacement without powering down the server. These include:

• Hard Drives: Drives can be removed and inserted from the front panel. Always ensure data is backed up and the drive is properly unmounted from the operating system before removal.
• Power Supplies: Redundant power supplies can be replaced individually from the rear panel.
• Fans: Fan modules are typically hot-swappable and accessible from the top cover.

Refer to the Cisco UCS C240 M3 Server Installation and Service Guide for detailed instructions on replacing specific components.

7.2 Cleaning

Periodically inspect the server for dust accumulation, especially around air vents and fan inlets/outlets. Use compressed air to gently clean dust from internal components and external surfaces. Ensure the server is powered off and disconnected from power before cleaning internal components.

7.3 Firmware Updates

Regularly check the Cisco support website for firmware updates for the server, RAID controller, and other components. Firmware updates can provide performance enhancements, bug fixes, and security improvements. Follow Cisco's recommended procedures for applying firmware updates.

8. Troubleshooting

This section provides guidance for resolving common issues.

8.1 LED Indicators

The server's front panel and individual components (e.g., power supplies, drives) feature LED indicators that provide status information. Consult the Cisco UCS C240 M3 Server Installation and Service Guide for a comprehensive list of LED patterns and their meanings.

• System Status LED: Indicates overall server health (e.g., green for normal, amber for warning, red for critical).
• Power Supply LEDs: Indicate power supply status (e.g., green for operational, amber for fault).
• Drive LEDs: Indicate drive activity, status, and fault conditions.

8.2 Common Issues and Solutions

• No Power:
  • Verify power cords are securely connected to the server and power source.
  • Check power supply LEDs.
  • Ensure the power source is active.
• Network Connectivity Issues:
  • Check Ethernet cable connections.
  • Verify network switch port status.
  • Confirm IP configuration in the operating system or IMC.
