SUPPLEMENTAL MATERIAL
Adding an Additional CPU (with CPU heat sink) or Replacing CPUs
All Cisco UCS two CPU socket-capable systems can be upgraded from having one to having two CPUs
configured or can also support replacement of the CPUs. You will need to order and install a heat sink when
adding any additional CPU to a system. Instructions for installing the new CPU or replacing CPUs and heat
sink can be found at the following link:

Motherboard Lithium Battery
You can order a replacement motherboard battery. Installation instructions are found at this link:
See the section titled “Replacing the Motherboard RTC Battery.”
Thermal Grease (with syringe applicator) for CPU to Heatsink Seal
Thermal grease must be applied to the top of the CPU where it comes in contact with the heat sink (a
grease syringe also ships with each CPU spare option kit). Instructions for applying thermal grease are found
at:

NOTE: Unlike previous generation systems, the HX240c M4 Node has tool-less CPU
sockets, so no separate tools (such as “pick n place” tools) are required to add or
replace CPUs.

CAUTION: Use only the thermal grease specified for this system
(UCS-CPU-GREASE3=). This thermal grease comes in a white-tipped
syringe and is to be used only in the HX220c M4 and HX240c M4 Nodes.
Other systems use thermal grease in a blue-tipped syringe
(UCS-CPU-GREASE=).
