Riser cards

To expand the server with PCIe modules, install riser cards on the PCIe riser connectors.
The models of riser cards follow certain rules:

Use RC-3FHHL/1FHFL-4U-G6 and RC-4HHHL-R4-4U-G6 as an example:
RC—Card type. RC represents riser card.

3FHHL/1FHFL—Support three FHHL modules and one FHFL module.

4U—4U height.

G6—Server generation.


Use RC-4HHHL-R4-4U-G6 as an example:
R4—Installation location. R4 represents PCIe riser connector 4.

The server supports the following models of riser cards:

RC-7FHHL-4U-G6

RC-3FHHL/1FHFL-4U-G6

RC-2FHHL/2FHFL-4U-G6

RC-4HHHL-R3-4U-G6

RC-1FHHL/1FHFL-R3-4U-G6

RC-2FHFL-R3-4U-G6

RC-4HHHL-R4-4U-G6
