CAUTION
!
Disassembling any part of the power supply voids the part
warranty and regulatory certifications. There are no
user-serviceable parts inside the power supply.
Because the cooling system relies on pressurized air, do not leave
either of the power supply slots empty longer than two minutes
while the switch is operating. If a power supply fails, leave it in the
switch until it can be replaced.
Maintain both power supplies in operational condition to provide
redundancy.
Table 3 describes the power supply status and system status LED
colors, behaviors, and actions required, if any.
