ATTENTION

Maintain all power supplies and fan assemblies in operational condition to provide redundancy.

CAUTION

Because the cooling system relies on pressurized air, do not leave any of the power supply or fan
slots empty longer than two minutes while the switch is operating. If a power supply or fan
assembly fails, leave it in the switch until it can be replaced.

CAUTION

Disassembling any part of the power supply or fan assembly voids the warranty and regulatory
certifications. There are no user-serviceable parts inside the power supply or fan assembly.

Table 7

describes the power supply status LED colors, behaviors, and actions required, if any.
