This server has two CPU sockets. Each CPU supports three DIMM channels (six DIMM slots). See Figure 3-12. This section includes the following topics:

•Special Information For Upgrades to Intel E5-2400 v2 Series CPUs, page 3-24

•Single-CPU Restrictions, page 3-25

Special Information For Upgrades to Intel E5-2400 v2 Series CPUs

Note Do not upgrade your Cisco UCS C22 server to Intel E5-2400 v2 Series CPUs if you use the server integrated under Cisco UCS Manager control. Cisco UCS C22 servers that have Intel E5-2400 v2 Series CPUs are not supported with Cisco UCS Manager integration at this time.

Caution You must upgrade your server firmware to the required minimum level before you upgrade to Intel E5-2400 v2 Series 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 E5-2400 v2 Series CPUs are as follows:

Table 3-6 Minimum Requirements For Intel E5-2400 v2 Series CPUs

Software or Firmware	Minimum Version
Server Cisco IMC	1.5(5)
Server BIOS	1.5(5)
Cisco UCS Manager	Not supported at this time.
(UCSM-managed system only)

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 E5-2600 v2 Series CPUs to upgrade your firmware. After you upgrade the software, return to the procedure in this section to replace the CPU and heatsink hardware.
