Figure 2
. The Fabric OS identifies the fan
locations from left to right as fan #3, fan #2, and fan #1.
CAUTION
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.
