How to install Chelsio 4-Port 1/10GbE UWire Adapter
- Power down the server and unplug all power sources before handling internal components.
- Open the server chassis and locate an available PCIe slot, preferably PCIe x8, to accommodate the Chelsio T540-CR.
- Install the half-height adapter into the PCIe x8 Gen 3 slot, ensuring the card sits firmly and the retention latch engages securely.
- Secure the card bracket to the chassis using the appropriate screw to prevent movement and ensure proper signaling.
- Attach SFP+ transceivers or direct-attach copper cables to the four SFP+ ports, selecting modules or DACs compatible with your network topology and distance requirements.
- Close the chassis, reattach power, and boot the server. Install or update the necessary drivers and management tools for Chelsio NICs as recommended by the operating system and Chelsio documentation.
- Configure each port in your operating system or virtualization environment to meet your networking policy, security, and performance goals. Validate link status and throughput with your preferred network testing tools.
