Replacing a power supply unit
CAUTION
Remove the power cord from a power supply before you install it in or remove it from the device.
Otherwise, the power supply or the device could be damaged as a result. (The device can be
running while a power supply is being installed or removed, but the power supply itself should
not be connected to a power source.)
CAUTION
For the Brocade ICX 6650 devices, be sure that the airflow direction of the power supply unit
matches that of the installed fan tray. The power supplies and fan trays are clearly labeled with
either a green arrow with an "E", or an orange arrow with an "I."
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.
The following table describes the Brocade ICX 6650 power supply status LED colors, behaviors, and
actions required, if any.
