Cisco UCS B200 M3 Blade Server Installation and Service Note

OL-26624-01

Working Inside the Blade Server

Figure 17 Replacing the Heat Sink (B200 M3 Shown)

Step 8 Using the syringe of thermal grease provided with replacement CPUs and servers (and available

separately as UCS-CPU-GREASE=, the only exceptions are Cisco UCS C220 M3 and and C240 M3

servers which use UCS-CPU-GREASE2= instead), add 2 cubic centimeters of thermal grease to the top

of the CPU where it will contact the heat sink. Use the pattern shown in Figure 18. This should require

half the contents of the syringe.

Figure 18 Thermal Grease Application Pattern

Caution The thermal grease has very specific thermal properties, and thermal grease from other sources should

not be substituted. Using other thermal grease may lead to damage.

Step 9 Replace the heat sink. See Figure 17, callout 4.
