System Node Tray Removal

Important

• Power Off Node First: Removing a powered-on node will cause immediate power loss.
• Independent Power: Each node operates with its own power supply. Turning off one node does not affect others.

Removal Steps

1. Pull the thumb latch aside to release the node.
2. Grasp the handle to gently slide the node out of its slot.

Support the weight of the node while removing it to prevent accidental drops.

CPU

Single Intel® Xeon® 6900P series processors, TDP up to 500W per node.

CPU and Heatsink Installation

Memory
Each node supports 12 DDR5 DIMM slots, compatible with RDIMMs, 3DS-RDIMM and MRDIMMs

DIMM Type	Max Frequency	Max Capacity per DIMM
RDIMM/ 3DS-RDIMM	6400 MT/s (1DPC)	256 GB
MRDIMM	8800 MT/s (1DPC)

⚠ Important

• There should be at least one DDR5 DIMM per socket.
• DDR5 memory configurations requires same DIMM types, ranks, speeds, and densities.
• Mixing vendors, non-3DS/3DS RDIMMs, 9×4 RDIMMs, or x8/x4 DIMMs is not allowed.
• Mixing DIMMs with different operating frequencies is not validated. When frequencies differ, the system defaults to the lowest common speed.
