3.7 PCI Expansion Cards
The system supports up to three PCIe cards on a riser card with three PCIe 4.0 x16 slots.
Use the jumper on the riser card, JSEL1, to configure.
The system supports full height or low profile expansion cards, although you must modify the
air shroud when using full height.
Installing or Replacing the Expansion Card Module
1. Power down the system as described in Section 3.1 and remove the chassis cover.
2. Remove the screws, as shown in the diagram on the following page.
3. Pull the locking lever up to release the expansion card module.
4. Gently pull the expansion card module upward with the aid of the plastic handle. There
are two cables connecting the motherboard and the expansion card module, so take
care not to jerk the cables.
5. If needed, detach the cables for convenient operation.
6. In the removed expansion card module, install expansion cards. For full height cards,
install first in the top-most slot, then the middle, and then the bottom slot. Note that you
must also modify the main air shroud to fit full height cards.
7. If the cables have been detached, reconnect the cables.
8. Replace the expansion card module and secure it with two screws.
9. Reinstall the chassis top cover, reconnect the AC power cord, and power up the system.
Caution:
If installing three NVIDIA T4 GPUs in the expansion card module, the processor
must consume less than or equal to 165W TDP.
