Special Information For Upgrades to Intel E5-2600 v2 Series CPUs
Caution You must upgrade your server firmware to the required minimum level before you upgrade to Intel
E5-2600 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 E5-2600 v2 Series
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 install 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, return to the procedure in this section to install the
CPU and heatsink hardware.
CPU Configuration Rules
This server has two CPUs. Each CPU supports four DIMM channels (12 DIMM slots). See Figure 3-14.
• The server can operate with one CPU or two identical CPUs installed.
• The minimum configuration is that the server must have at least CPU1 installed. Install CPU1 first,
then CPU2.
Note The following restrictions apply when using a single-CPU configuration: the maximum number
of DIMMs is twelve, the internal mezzanine card slot is unavailable, and PCIe riser 2, which
contains PCIe slots 4 and 5, is unavailable.
