GPU installation guidelines

• The processor must be of 135 W or less.
• Due to the high power consumption of GPUs, the ambient system inlet temperature is restricted to
25°C to ensure adequate system cooling when one or more GPU cards are installed.
NOTE: Certain system configurations may require reduction in the maximum ambient system
inlet temperature limit. The performance of the system may be impacted when operating above
the maximum temperature limit or with a faulty fan.
• All GPUs must be of the same type and model.
• You can install up to four GPUs.
NOTE: Incorrect removal and installation of the GPUs will cause operational issues to your system.
