Procedure
1. Remove the front bezel. The fan assemblies will then be visible.
2. Identify the fan to be replaced.
Fans are labeled on the chassis, and are numbered 1 and 2, with fan 1
on the left and fan 2 on the right. Refer to the fan status LEDs on front
panel of the server (behind the bezel) to see which fan has failed. In the
following figure, number 1 indicates the status LED for fan 1 (the left-
side fan), and number 2 indicates the status LED for fan 2 (the right-side
fan).
