Installing Field-Replaceable Units (FRUs) This section lists FRUs and provides installation procedures. 8/8 SAN Switch and 8/24 SAN Switch FRU units No components in the 8/8 SAN Switch and 8/24 SAN Switch are field replaceable. If the switch becomes inoperable, replace the entire switch. 8/40 SAN Switch and 8/80 SAN Switch FRU units Replace the following FRUs as required. • Power supply assembly • Fan assembly 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. 4. Verify that the fan status LED is lit steady green to indicate normal operation. 5. Optionally, display the fan status using the fanShow command from the CLI. 56 Operating the 8Gb SAN Switch
