Fan removal and replacement

The switch has three fans as displayed in Figure 3 on page 5. The Fabric OS
identifies the fan locations from left to right as fan #3, fan #2, and fan #1 as viewed
from the nonport side of the switch.
Attention: Disassembling any part of the fan voids the part warranty and
regulatory certifications. There are no user-serviceable parts inside the fan. Because
the cooling system relies on pressurized air, do not leave any of the fan slots
empty longer than two minutes while the switch is operating. If a fan fails, leave it
in the switch until it can be replaced. Maintain all three fans in operational
condition to provide redundancy.
Refer to Table 7 on page 36 for the fan status LED colors, behaviors, and actions
required, if any.
Attention: Do not force the installation. If the power supply does not slide in
easily, ensure that the power supply is correctly oriented before continuing.
