Cooling Fans
The system has either five or four hot-swappable fans to provide cooling to
the system’s interior components.
• Dual-processor configurations have five fans.
• Single-processor configurations have four fans (fans 1 through 4) and a
blank inserted in the fan 5 bay. Fan 5 can be installed as an optional fan.
NOTE:
In the event of a problem with a particular fan, the fan’s number is
referenced by the system’s management software, allowing you to easily identify
and replace the proper fan.
Removing a Cooling Fan
CAUTION:
Many repairs may only be done by a certified service technician. You
should only perform troubleshooting and simple repairs as authorized in your
product documentation, or as directed by the online or telephone service and
support team. Damage due to servicing that is not authorized by Dell is not covered
by your warranty. Read and follow the safety instructions that came with the
product.
CAUTION:
The cooling fans are hot-swappable. To maintain proper cooling while
the system is on, replace only one fan at a time.
CAUTION:
On single-processor systems using four fans, the fan blank must be
installed in the FAN5 bay to maintain proper cooling while the system is on.
NOTE:
If a fan is installed in FAN5 in a single-processor configuration, the fan will
still be operational, however the fan will not appear in the iDRAC user interface
unless the fan was installed before the system was started.
1 Open the system. See "Opening the System."
WARNING:
Use caution when handling the fan until the fan blades stop spinning.
2 Press the release tab while grasping the ends of the fan and lift the fan
straight up from the fan bracket. See Figure 3-14.
