Figure 4-13 shows the PCIe Native Expansion Tray attached to an nx360 M4
(shown with the top cover removed). The figure shows two NVIDIA GPUs
installed.

Ordering information is listed in Table 4-20.
Table 4-20 Ordering information
When the PCIe Native Expansion Tray is used, it is connected to the compute
node via two riser cards, each providing a PCIe x16 connector to the GPUs or
coprocessors installed in the tray. Riser cards are as follows:
򐂰 2-slot PCIe 3.0 x24 riser card installed in the front riser slot (riser slot 1 - see
Figure 3). This riser card replaces the standard 1-slot riser used to connect
standard PCIe cards internal to the compute node. The 2-slot riser card offers
these connection:
– PCIe 3.0 x8 slot for the slot internal to the compute node
– PCIe 3.0 x16 slots for the front adapter in the PCIe Native Expansion Tray
򐂰 1-slot PCIe 3.0 x16 riser card installed in the rear riser slot (riser slot 2 - see
Figure 4-3 on page 62). This riser is used to connect the rear adapter in the
PCIe Native Expansion Tray.
