Removing and installing the system fan
The system has two cooling fan assemblies — two fan modules for each
assembly — located on the front panel and four cooling fans located at
the rear of the chassis.
Cautions:
• System fan hot-swap operations should be performed only if a
failure occurs in the fan assembly.
• System cooling is reduced during the fan replacement process. Do
not leave a system fan removed for longer than two minutes.
• Do not touch the fan blades while they are turning.
