To remove all electrical current from the device, ensure that all power cords are disconnected from 
the power source.
Attention: 
•  Read the 
“Installation guidelines” on page 61 to ensure that you work safely.
•  Use any documentation that comes with the PCIe adapter and follow those instructions in addition to the 
instructions in this section.
•  Touch the static-protective package that contains the component to any unpainted metal surface on the 
server; then, remove it from the package and place it on a static-protective surface.

Four PCIe slots are available in this server. Follow the following priority when installing PCIe adapters. 
•  When one of the following adapters are to be installed, install it to Slot 2: 
–  ThinkSystem NVIDIA Quadro RTX T1000 8GB PCIe Active GPU
–  ThinkSystem NVIDIA Quadro RTX T400 4GB PCIe Active GPU 
Note: GPU adapters can only be installed in PCIe slot 2. When GPU adapter is installed in PCIe slot 2, 
make sure to keep PCIe slot 3 empty.
