Removing and Installing System Fans
System fans provide cooling for each node. Front I/O nodes have rear external fans and rear
I/O nodes have front internal fans. These fans circulate air through the node as a means of
lowering the internal temperature. The F424AS2 system fans are easily removed from the fan
tray. There is no need to uninstall any other parts when replacing fans, and only a Phillips
screwdriver is required for installation.
Replacing a Front Internal System Fan
1. Determine which serverboard node contains the failed fan,.Remove the node from
the chassis as described in Section 3-2 and place the node on a flat, stable surface.
Remove the cover from the node as described in Section 3-2.
2. Remove the one screw securing the air shroud and lift the air shroud up and out of the
node.
3. Disconnect all fan cables from the motherboard.
4. Remove the screws securing the fan housing to the floor of the node and set them aside
for later use.
5. Lift the fan housing up and out of the chassis.
6. Simultaneously squeeze both sets of release tabs on each side of the fan housing.
This will release the cover plate of the housing which holds the fans inside the housing.
Either the front or rear cover plate may be released.
7. Pull the cover plate off the fan housing.
8. Remove the four rubber spacers from the housing.
9. Pull out the failed fan and replace it with a new one.
10. Reinstall the rubber spacers in the fan housing.
11. Reinstall the face cover of the fan housing, by aligning the release tabs with their slots
in the housing and gently pushing the face cover onto the housing until it clicks into the
locked position.
12. Reconnect the cabling to both fans.
13. Reinstall the fan housing in the serverboard node and secure it to the floor of the node
with the four screws which were previously set aside.
