Replacing a hot-swap fan
Your server comes with three hot-swap processor fans (labeled and numbered 1, 2,
and 3) in the front of the processor housing assembly at the front of the server, and
three hot-swap I/O fans (labeled and numbered 4, 5, and 6) behind the hot-swap
drive bays. Each fan has an LED; the fan LEDs are amber in color. A fan LED is
lit only when the fan needs replacement.
Notes:
1. The illustrations in this section might differ slightly from your hardware.
2. You do not need to turn off the power to the server to replace a fan.
3. Replace a fan that has failed as soon as convenient to maintain the redundant
cooling capability.
4. The top cover is in place during normal operation. If the server is on, do not
leave the top cover off for more than 30 minutes at a time.
To replace a hot-swap fan:
To replace a processor fan, continue with “Replacing a processor fan.”
