ATTENTION
Maintain all power supply 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 and
fan assembly 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 and fan assembly voids the warranty and regulatory
certifications. There are no user-serviceable parts inside the power supply and fan assembly.
