Replacing a PCIe Card
Cisco supports all PCIe cards qualified and sold by Cisco. PCIe cards not qualified or sold by Cisco are the
responsibility of the customer. Although Cisco will always stand behind and support the C-Series rack-mount
servers, customers using standard, off-the-shelf, third-party cards must go to the third-party card vendor for
support if any issue with that particular card occurs.
Note
PCIe Slot Specifications
The server contains two PCIe slots on one riser assembly for horizontal installation of PCIe cards. Both slots
support the NCSI protocol and 12V standby power.
