Installing a power supply unit

Prerequisites
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.
NOTE: When installing, hot-swapping, or hot-adding a new power supply unit (PSU), allow several
seconds for the system to recognize the PSU and determine its status. The PSU status indicator
turns green to indicate that the PSU is functioning properly.
1. Ensure that you read the
2. Remove the PSU.
NOTE: You must remove a power supply to replace a faulty power supply, service other
components of the system, or to reduce chassis weight when installing the enclosure in the
rack.
Steps
1. Slide the PSU into the enclosure until the PSU is fully seated and the release latch snaps into place.
CAUTION: When connecting the power cable, secure the cable with the strap.
2. Connect the power cable to the PSU and plug the cable into a power outlet.

Cooling fans

Your system supports eight hot-swappable cooling fans that provide cooling to the I/O components in
the system.
To provide increased cooling to the PCIe components in the system, you can change the Fan Offset
options from the CMC web interface.
For more information on the Fan Offset properties, see Advanced Fan Configuration in the CMC Online
Help.
NOTE: If you are removing a fan, replace it immediately with another fan. Operating the system for
an extended period of time without a fan installed can cause the enclosure to overheat.
NOTE: In the event of a problem with a particular fan, the fan number is referenced by the system's
management software, allowing you to easily identify and replace the appropriate fan by noting the
fan numbers on the cooling-fan bay. If any of the fans fail, the LEDs on the fan light up.
NOTE: The cooling fans in your system are shipped in two sizes of 80 mm and 60 mm width.
