Brocade 5300 Fan Assembly Replacement Procedure 3 of 6

Fan assembly replacement
The Brocade 5300 switch has three fan assemblies as displayed in Figure 1. Fabric OS identifies the fans from left
to right as Fan assembly #3, Fan assembly #2, and Fan assembly #1.
FIGURE 1 Brocade 5300 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.
