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.

a. Orient the new fan assembly as shown in Figure 2, with the captive screw on the right.
b. Gently push the fan assembly into the chassis until it is firmly seated.
CAUTION
Do not force the installation. If the fan assembly does not slide in easily, ensure that it is correctly
oriented before continuing.
c. Using the Phillips-head screwdriver, secure the fan assembly to the chassis by tightening in the captive
screw.
