Cisco UCS C-Series Servers Upgrade Guide for Intel Xeon v3 Series CPUs
Downgrading From Intel Xeon v3 Series CPUs
Use the Cisco IMC firmware management procedures in the GUI or CLI Integrated Management
Controller Configuration Guide for your release.
Downgrade Scenario 2: Standalone Server
This scenario assumes the following conditions:
• The C-Series server is in standalone mode.
• The C-Series server is using the BIOS/Cisco IMC minimum version or later (seeMinimum Software
and Firmware Requirements, page 2).
• The C-Series server is using the Intel Xeon v3 Series CPUs.
Use the following procedure to downgrade to earlier supported CPUs, memory risers, and DIMMs.
Step 1 Power off the server.
Step 2 Replace the Intel Xeon v3 Series CPUs with the earlier supported CPUs.
Use the CPU replacement procedures in the Installation and Service guide for your server: Cisco UCS
C-Series Installation and Upgrade Guides.
Step 3 Replace the DDR4 memory risers and DIMMs with the earlier supported DDR3 memory risers and
DIMMs.
Use the memory riser and DIMM replacement procedures in the Installation and Service guide for your
server: Cisco UCS C-Series Installation and Upgrade Guides.
Step 4 Power on the server.
Note The Cisco IMC bundle, including the server Cisco IMC and BIOS, is backward-compatible with
earlier supported CPUs, so the following firmware downgrade steps are optional.
Step 5 Optional: Downgrade your server Cisco IMC.
Use the Cisco IMC firmware management procedures in the GUI or CLI Integrated Management
Controller Configuration Guide for your release.
Step 6 Optional: Downgrade your server BIOS.
Use the Cisco IMC firmware management procedures in the GUI or CLI Integrated Management
Controller Configuration Guide for your release.
