1.N20-AI0002, the Cisco UCS 82598KR-CI 10 Gb Ethernet Adapter, is not supported on this server but is still
available for other models. We suggest you use the Cisco UCS CNA M61KR-I Intel Converged Network Adapter
in place of the Cisco UCS 82598KR-CI 10 Gb Ethernet Adapter.
2. Requires UCS Manager 2.0(2) or later.
If you are switching from one type of card to another, before you physically perform the switch make
sure you have downloaded the latest device drivers and loaded them into the server's OS. For the most
recent details, refer to the firmware management chapter of one of the UCS Manager software
configuration guides.
