    Caution - If a power supply has shut down because of a thermal or overcurrent condition, signified by the amber Attention LED lighting, remove the respective power cord from the chassis. Allow the power supply to completely cool for at least 15 minutes. A shorter cooling time might cause damage to the power supply when the power cord is reattached. If the Attention LED lights amber upon reattaching the power cord, replace the power supply.
