PCIe adapter placement rules and slot priorities for the 8335-GCA or 8335-GTA

Find information about the placement rules and slot priorities for the Peripheral Component Interconnect (PCI) Express (PCIe) adapters that are supported for the 8335-GCA or 8335-GTA system.

PCIe slot descriptions for the 8335-GCA or 8335-GTA

The 8335-GCA or 8335-GTA system provides PCIe generation 3 slots. Table 1 lists the PCIe adapter slot locations and details for the 8335-GCA or 8335-GTA system. Figure 1 shows the rear view of the system with the PCIe adapter slots.
  • The full-height, full-length adapters can be installed only in the full-height, full-length slots 1 and 4.
  • The half-height, half-length or short (low-profile) adapters can be installed in slots 2, 3, and 5.

1Slots 4 and 1 are made available by the internal PCIe riser.

2Slots 4 and 1 can be filled with a PCIe3 x16 graphics processing unit (GPU) adapter (FC EC49) or a full-height, full-length adapter in the 8335-GCA. Mixing of a GPU adapter and a full-height, full-length adapter is supported on this model.

3Slots 4 and 1 must be used to install a GPU adapter (FC EC49) in the 8335-GTA.

4Slots 5 and 3 are x8 slots. The adapter priority for these slots is for the high-performance adapters followed by any other adapter.
