Cisco HX C245 M6 Server (HX-C245-M6SN) server is also available as GPU Ready Configuration unit. The server is configured to accept GPU, but GPUs are not installed while placing the order.

GPU Ready Configuration units are shipped with low profile heatsink: HX-HSLP-C245M6 and HX-ADGPU-245M6 (GPU air duct).


Note

GPU Ready Configuration should follow the same temperature limit as GPU configured unit. You should select the GPU airduct PID to enable GPU Ready Configuration. Follow Cisco Commerce Workspace (CCW) rules for more details.
