Chassis front view

This section contains information on the front of the chassis installed with nodes.

The chassis can contain up to four 1U nodes or up to two 2U nodes.

Table 1. Nodes supported in D3 Chassis
	1U nodes	2U nodes
Intel	SD530 V3, Types 7DD3 and 7DDA (User Guide) SD520 V4, Types 7DFY, 7DFZ, 7DG0, and 7DG1 (User Guide)	SD550 V3, Types 7DD2 and 7DD9 (User Guide)
AMD	SD535 V3, Types 7DD1 and 7DD8 (User Guide)

Note

ThinkSystem V4 nodes cannot be mixed with ThinkSystem V3 nodes within the same chassis.

Important

For proper cooling, each node tray must be installed with either a node or node tray fillers before the nodes in the chassis are powered on.
The installation of nodes must follow the sequence of the tray numbering.

Four 1U nodes

For four 1U nodes: the two nodes in the right trays ( 2 and 4 ) must be installed upside down.

The following illustration shows the front view of the chassis and respective node trays in the chassis.

For two 1U nodes and one 2U node:

One 2U node in the left tray and two upside-down 1U nodes in the right trays ( 2 / 4 ).
