Removing the Xeon Phi 5110P/7120P Cards
WARNING: Working on systems that are still connected to a power supply can be
extremely dangerous.
CAUTION: The sled must be operated with the cover installed to ensure proper
cooling.
CAUTION: To ensure proper airflow in the PowerEdge C8000 server enclosure, if
a sled module is removed it should be immediately replaced with another sled or
sled blank.
CAUTION: Operating the system for extended periods of time without a sled blank
installed can cause the PowerEdge C8000 server enclosure to overheat.
CAUTION: Xeon Phi cards can only be installed in the slots on the GPGPU card
risers. Do not attempt to install Xeon Phi cards directly into the riser connector on
the system board.
CAUTION: When replacing the back Intel Xeon Phi 5110P/7120P card, ensure that
the back GPGPU card riser is installed on the sled cover with the proper screw
holes. If the GPGPU card riser is not installed with the correct screw holes, the
GPGPU card will not seat properly into the riser connector. Be sure the card riser
is installed through the "type A" screw holes. See "Installing the Back GPGPU Card
Riser" on page 271 for the location of the screw holes.
NOTE: The procedure for removing the Xeon Phi 5110P and 7120P cards are
similar.
