Removing the NVIDIA Tesla K20 GPGPU Cards
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 is not covered by
warranty. Read and follow the safety instructions that came with the product.
CAUTION: Expansion cards can only be installed in the slots on the expansion
card riser. Do not attempt to install expansion cards directly into the riser
connector on the system board.
CAUTION: When replacing the back NVIDIA Tesla K20 GPGPU 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 B" screw holes. See "Installing the Back GPGPU Card
Riser" on page 271 for the location of the screw holes.
