Fan assembly replacement
This group of switches has three fan assemblies as displayed in Figure 1.
FIGURE 1 Fan assemblies on the nonport side
CAUTION
Disassembling any part of the fan assembly voids the part warranty and regulatory certifications. There
are no user-serviceable parts inside the 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 three fan assemblies in operational condition to provide redundancy.
Table 1 describes the fan status LED colors, behaviors, and actions required, if any.
