Gigabit Ethernet/82543 PMC Installation and Use

Board Damage
Do not operate the product outside the specified environmental limits. 
High humidity, temperature and condensation may cause short circuits. 

Therefore, ensure that the product is completely dry and there is no 
moisture on any surface before applying power.
