ASUS Troubleshooting Solution
ASUS Debug header is a 10-1 pin low pin count (LPC) header for connecting to debug cards for faster, more efficient motherboard troubleshooting. When an ASUS debug card is connected, administrators can view error and debugging codes on the integrated LCD display, and get a better idea of initialization and recovery processes. ASUS business motherboards provide a complete troubleshooting solution, making mass production faster and more cost effective.

* LPC debug card is sold separately.
* Specifications and features vary by model, and all images are illustrative. Please refer to specification pages and gallery for full details.

24/7 Reliability Test
Optimized for 24/7 operation, the motherboard is tested under temperatures of up to 45°C and relative humidity of up to 80% to ensure it can handle diverse temperature and humidity ranges of different locations.

Anti-moisture coating
Protection against moisture and corrosion
An innovative moisture-resistant coating protects the motherboard in humid environments such as factories, libraries, data centers and internet cafes. It also minimizes internal corrosion by preventing adhesion and migration of moisture, prolonging the life of the motherboard.

Anti-sulfur resistors
Consider long-term reliability, ASUS business motherboard is equipped with anti-sulfur resistors. The resistors provide excellent resistance to sulfuration as they are constructed using a high-grade ceramic body (aluminum oxide). With anti-sulfur resistors, the ASUS Business motherboard can be operated in harsh environments as well.
