IBM AA-RWF3A-TE - Manual (Page 107)

CAUTION:
Disassembling any part of the fan assembly voids the part warranty and regulatory
certifications. There are no user-serviceable ports inside the Power Supply/Fan
Assembly Unit.
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 installed in the switch until it can be replaced.
Maintain the two Power Supply/Fan assemblies in operating condition to provide
redundancy.
Table 21 lists power supply/fan assembly unit status LED descriptions, and required
actions.
