IBM AA-RWF3A-TE manual 4/32B SAN Switch power supply/fan assembly unit status LED

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.
