Figure 32. Removing the heat sink
b) Grip the heat sink (B) on opposing sides and remove the heat sink by lifting it upward. Set the heat
sink aside with the module side facing upward.
c) Repeat steps "17.a" on page 32 through "17.b" on page 33 to remove the remaining heat sinks.

b) Open the system processor module tray packages, which were included with the replacement
system backplane kit.
