This document describes the Lenovo Net Security Isolation Card, a hardware module that provides complete electrical isolation between internal and external networks. It operates independently and ensures that data transferred across the card remains fully isolated for security.
The guide covers installation steps (connecting the 4‑pin and 6‑pin connectors, setting the Master/Slave ports, and BIOS configuration), normal usage procedures, and troubleshooting tips such as checking connector integrity and BIOS settings. This manual is written in Chinese.
