Installing or Replacing Server Components
Replacing a PCIe Card Caution 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 third-party card occurs.
