Important Safety Information
Observe the following safety precautions when installing NVIDIA Tesla K20 GPGPU cards in the
PowerEdge C8220X sled.
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: GPGPU cards can only be installed in the slots on the GPGPU card riser. Do not
attempt to install GPGPU expansion cards directly into the riser connector on the system
board.
NOTE: It is recommended that you always use a static mat and static strap while working on
components in the interior of the system.
To avoid injury to yourself or damage to your system, follow these guidelines:
• Always disconnect the system from the power outlet whenever you are working inside the
system.
• If possible, wear a grounded wrist strap when you are working inside the system.
Alternatively, discharge any static electricity by touching the bare metal chassis of the
system case, or the bare metal body of any other grounded appliance.
• Hold electronic circuit boards by the edges only. Do not touch the components on the
board unless it is necessary to do so. Do not flex or stress the circuit board.
• Leave all components inside the static-proof packaging until you are ready to use the
component for the installation.
• Some cables have a connector with locking tabs; if you are disconnecting this type of cable,
press in on the locking tabs before you disconnect the cable. As you pull connectors apart,
keep them evenly aligned to avoid bending any connector pins. Also, before you connect a
cable, ensure that both connectors are correctly oriented and aligned.
