2. From the front of the enclosure, open the fan tray access cover. Using a No. 2 Phillips screwdriver, loosen the two captive screws on the left and right sides. See FIGURE 3-11. FIGURE 3-11 Removing the Fan Tray Cover 3. Identify the defective fan module. A defective fan module shows a lit amber (middle) LED: The fan should be replaced. Note - If both green and amber indicators are on, then one of the two fans in the fan module is still operational. You should replace this fan module last if there is more than one fan module failure. 3-26 Sun Fire X4500/X4540 Server Service Manual • May 2010
