Insert the top runner of the fan tray through the notch in the top of the chassis. Continue
pushing the tray into the chassis, and ensure that the bottom runner slides into the track on
the floor of the chassis. If the tray hangs up, pull it back out a few inches and try pushing it
back in again. If the runners seem to be catching on the brackets, push the tray slightly
toward the left when inserting it again.
Slide the tray back into the chassis, pushing it all the way in until the circuit board snaps
into the backplane socket.
Replace the M-4 screw in the tab and tighten it with a number 2 Phillips screwdriver.
