Next steps
Follow the procedure listed in After working inside your system on page 57.
Cooling fans
The cooling fans are integrated into the system to dissipate the heat generated by the functioning of the system. These fans
provide cooling for the processors, expansion cards, memory modules.
Your system supports up to six standard or high performance hot swappable cooling fans.
For single processor systems without a mid hard drive tray, only four cooling fans are required. Fan bays 1 and 2 are covered by
a fan blank.
CAUTION: Mixing of standard and high performance cooling fans is not supported.
NOTE: Each fan is listed in the systems management software, referenced by the respective fan number. If there is a
problem with a particular fan, you can easily identify and replace the proper fan by noting the fan numbers on the cooling
fan assembly.
Removing a cooling fan
The procedure for removing standard and high performance fans is identical.
Prerequisites
WARNING:
Opening or removing the system cover when the system is on may expose you to a risk of electric
shock. Exercise utmost care while removing or installing cooling fans.
CAUTION: The cooling fans are hot swappable. To maintain proper cooling while the system is on, replace only
one fan at a time.
