Riser cards

This section provides cable routing information for riser cards.

The server supports up to four riser cards: riser card 1, riser card 2, riser card 3, and internal riser card. Among which, the following riser cards need cable connections:

The riser card types vary by server model. For detailed information, see Rear view.

Riser card 1 cable connections​

Note
The cable connections for x16/x16 PCIe riser card 1 and x16/x8/x8 PCIe riser card 1 are the same.

Note

x16/x16 or x16/x8/x8 PCIe riser card 1 is not supported if three 8x 2.5-inch front drive backplanes are connected to onboard PCIe connectors.

Riser card 3 (x8/x8 PCIe) cable connection​

Note

x8/x8 PCIe riser card 3 is not supported if the server has a 12 x 3.5-inch AnyBay backplane or 8 x 2.5-inch NVMe backplane installed.

Note

x16/x16 PCIe riser card 3 is not supported if the server has a 12 x 3.5-inch AnyBay backplane, 12 x 3.5-inch SAS/SATA front backplane (on board), 8 x 3.5-inch SAS/SATA front backplane (on board), 8 x 2.5-inch NVMe backplane, or M.2 drive installed.

Riser card 3 power and sideband connection​

Note
The power and sideband connections for x8/x8 PCIe riser card 3 and x16/x16 PCIe riser card 3 are the same.
