Hot-swapping a Fan
To perform this procedure, you will first need to remove the top cover. The steps below will direct you to the instructions to remove the top cover at the appropriate location in the step sequence.
Cautions:
•Replace the fan within two minutes of removing the failed fan. If a fan bay remains unpopulated for more than two minutes, the cooling system could fail.
•Remove only the failed component. Removing the incorrect component could cause the system to malfunction.
1.Remove the top cover. For instructions, see “Removing the Top Cover” on page 36.
2.Confirm that the cooling fan LED is turned off. This indicates the fan has a fault. See letter “A” in the following figure.
