Replacing Node Fans
Replace the failed node fan with an identical 4-cm, 12-volt counter-rotating fan (p/n
FAN-0157L4, available from Supermicro). See Figures 6-4 and 6-5.
Replacing Fans
1. Shutdown the node with the failed fan(s) and remove the AC power cord.
2. On the node with the failed fan, push the release bar down to unlock the
serverboard tray.
3. Use the bar to pull the node/serverboard from the chassis.
4. Remove the failed fan from the assembly and replace it with an identical
replacement. You may need to remove the assembly to replace the lower fan.
5. Slide the serverboard tray back into the chassis. When seated, lift the release
bar to lock it into place.
6. Reconnect the AC power cord and power up the node.
7. Inspect the replaced fan to verify it is working.
