Chapter 2: Installation
4. With the CPU inserted into the
socket, inspect the four corners of the
CPU to make sure that it is properly
installed and fl ush with the socket.
5. Gently press the CPU socket lever
down until it locks in the plastic tab.
For a dual-processor system, repeat
these steps to install another CPU into
the CPU#2 socket.
Note: if using a single processor, only
CPU 1 DIMM slots are addressable.
Installing the Heatsink Retention Modules
Two heatsink retention modules (BKT-0005) and four screws are included in the
retail box. Once installed, these are used to help attach the heatsinks to the CPUs.
To install, position the module so that the CPU backplate standoffs insert through the
holes on the heatsink retention module and the four feet on the module contact the
serverboard. Secure the retention module to the backplate with two of the screws
provided. See Figure 2-1. Repeat for the second CPU socket. Note: BKT-0005
is included for use with non-proprietary heatsinks only. When installing proprietary
heatsinks, only BKT-0004 (CPU backplate) is needed. The BKT-0005 retention
module was designed to provide compatibility with clip-and-cam type heatsinks
from third parties.

Installing the Heatsink
We recommend the use of active type heatsinks (except for 1U systems). Use the
Fan7 header for the CPU1 fan and the Fan8 header for the CPU2 fan due to fan
monitoring and wiring considerations. To install the heatsinks, please follow the
installation instructions included with your heatsink package (not included).
