Table 16 Fan status LED behavior, description, and required actions LED color and behavi- Description or Action required No light Fan assembly is not receiving power. Verify that the fan FRU is seated correctly. Steady green Fan assembly is operating normally. No action required. Steady amber (for more than five seconds) Fan fault for one of the following reasons: One or more of the fan(s) in the fan assembly has failed. The fan FRU was disabled by the user. Verify that the fan FRU is enabled. If the fan FRU is enabled and the FRU is faulty it should be replaced. Replacing the 8/40 SAN Switch power supply and fan assembly CAUTION: Disassembling any part of the power supply and fan assembly voids the warranty and regulatory certifications. There are no user-serviceable parts inside the power supply and fan assembly. Because the cooling system relies on pressurized air, do not leave any of the fan assembly slots empty longer than two minutes while the switch is operating. If a fan assembly fails, leave it in the switch until it can be replaced. Maintain all fan assemblies in operational condition to provide redundancy. Replacing the power supply and fan assembly unit takes approximately two minutes. You will need: • 8/40 SAN Switch • New power supply and fan assembly FRU (one unit) • Phillips-head screwdriver #1 To replace the power supply and fan assembly unit: 1. Unscrew the captive screw on the power supply fan assembly you are replacing using a Phillips-head screwdriver. 2. Remove the power supply fan assembly you are replacing from the chassis by pulling the handle out, away from the chassis. 3. Install the new power supply fan assembly unit in the chassis: a. Orient the new fan assembly with the captive screw on the right. b. Gently push the power supply fan assembly into the chassis until it is firmly seated. CAUTION: Do not force the installation. If the power supply fan assembly does not slide in easily, ensure that it is correctly oriented before continuing. c. Secure the fan assembly to the chassis by screwing in the captive screw using the Phillips-head screwdriver. 72 Managing the 8-Gb SAN Switches
