Hot-Swapping A Fan; Removing A Fan - Intel AC450NX Product Manual

AC450NX Rack Server System Product Guide

Hot-Swapping a Fan

The server contains six fans in a (5 + 1) redundant configuration for cooling system components. If
a single fan fails, the yellow fan failure LED on the front panel turns on. A fan-fail LED mounted
next to each fan identifies the failed fan. You can easily hot-swap the defective fan without
turning the server power off.
CAUTION
Even though the server can continue operating with only five fans, the
defective fan must be replaced in a reasonable amount of time.

Removing a Fan

See Figure 9-1.
1. Remove and save the screw that secures the fan array cover.
2. Slide the fan array cover to the server front to free the cover from the locking tabs and lift the
cover.
NOTE
The fan array cover can be removed by first removing the top cover. See Chapter 12, "Server
Covers: Removing/Reinstalling."
3. Look at the yellow fan failure LEDs to determine which fan is defective.
WARNING
The fan blade may still be rotating. To avoid injury wait until it stops
rotating before grabbing the fan with your free hand.
4. Use the grasp holes and remove the defective fan.
5. Set it aside.
