Replace a Fan
If a fan fails, the remaining fans ramp up to full speed, the Error LED on the control panel
lights, and an email alert is sent to the system administrator. Replace a failed fan as soon
as possible. Remove the top chassis cover while the system is still running to determine
which fan failed.
Fans are hot-pluggable, so you do not need to power down your system when replacing
a fan.
