CAUTION: In case of bodily injuries, do not touch any naked wire, terminal or

 

c other parts of the product with hazardous voltage labels.

 

Step 1: Wear the ESD-preventive wrist strap, making sure that it makes good skin

 

contact; take the fan tray out from the packing bag.

 

Step 2: Hold the fan tray in right direction (just check the direction of instructional

 

words, and if you insert it upside down, the plug of the fan tray cannot touch the

 

right socket inside the chassis), with one hand on its handle and the other hand at

 

its bottom the ejector levers on the fan tray with both hands and pull them

 

outward. Align the fan tray with the guides in the chassis and slide it gently into

 

the slot until its plug touches the chassis socket.

 

Step 3: Fasten the mounting screws on the panel of the fan tray with a screw

 

driver.

 

The above installation steps are just for replacing your fan tray, since the fan tray

 

n is delivered together with the chassis and no initial installation is required.
