Replacing the cooling fan
The cooling fan is hot-swappable, so you can replace the cooling fan
without powering down the server.
When to hot-swap the cooling fan
When the LED associated with a cooling fan turns red, the fan requires
replacement.
To hot-swap a cooling fan
1 Remove the front bezel.
2 Use the front panel display LED to locate the defective fan.
3 Loosen the thumbscrew located on the outside of the failed cooling
fan module (see A Figure 22 on page 127).
If needed, use a flat-blade screwdriver. The thumbscrew must
rotate freely and not contact the chassis threads.
