Replacing Modules
c) Position the fan module in front of the open fan slot (be sure that the backside of the module with the electrical
connectors is positioned to enter the slot first) and slide the module all the way into the chassis until its front side
comes in contact with the chassis. For the last 0.2 inches (0.5 cm), carefully mount the module onto the chassis
