Special Information For Upgrades to Intel Xeon v4 CPUs
Caution You must upgrade your server firmware to the required minimum level before you upgrade to Intel v4
CPUs. Older firmware versions cannot recognize the new CPUs and this results in a non-bootable server.
The minimum software and firmware versions required for the server to support Intel v4 CPUs are as
follows:
Do one of the following actions:
• If your server’s firmware and/or Cisco UCS Manager software are already at the required levels
shown in
Table 3-6 , you can replace the CPU hardware by using the procedure in this section.
•
If your server’s firmware and/or Cisco UCS Manager software is earlier than the required levels, use
the instructions in the
Cisco UCS C-Series Servers Upgrade Guide for Intel Xeon v4 CPUs to
upgrade your software. After you upgrade the software, return to the procedure in this section as
directed to replace the CPU hardware.
CPU Configuration Rules
This server has two CPU sockets. Each CPU supports four DIMM channels (12 DIMM sockets). See
Figure 3-15 .
• The server can operate with one CPU or with two identical CPUs installed.
•
The minimum configuration is that the server must have at least CPU1 installed. Install CPU1 first,
and then CPU2.
• The following restrictions apply when using a single-CPU configuration:
–
The maximum number of DIMMs is 12 (only CPU1 channels A, B, C, and D).
– PCIe riser 2, which contains PCIe slots 4, 5, and 6 is unavailable.
–
The PCIe SSD interposer board is unavailable.
