How to use

Power down the computer and open the chassis according to the system manufacturer's instructions. Install the MC-JL82576EB into an available PCIe x4 (or larger) slot and secure the bracket to the case. Attach the appropriate bracket (standard or low-profile) before closing the chassis. Boot the system, install any required drivers provided by the operating system or MicroConnect, and connect network cables to the RJ45 ports. Configure IP settings for IPv4 or IPv6 as needed in the operating system or network management tools.

Recommendations

Use shielded twisted-pair Ethernet cables (Cat5e or higher) for reliable Gigabit links and ensure the system BIOS and operating system are up to date to support PCIe device enumeration. For rack or small-form-factor cases, use the included low-profile bracket if needed. In virtualized or high-traffic environments, verify driver support and offload feature settings for optimal performance.
