9 Hot-swappable Fans: Hot Swapping

This chapter tells how to hot-swap a fan.
When the yellow fan failure LED on the front panel turns on, you can determine which fan is
defective by checking the yellow fan failure LEDs mounted next to each fan. When a fan fails, the
LED will be on continuously. However, you do not need to shut the server down to hot-swap a
failed fan.
