Installing the Heatsink
The use of active type heatsinks (except for 1U systems) are recommended.  Con-
nect the heatsink fans to the appropriate fan headers on the serverboard.  To install 
the heatsinks, please follow the installation instructions included with your heatsink 
package (not included).     
Installing the Heatsink Retention Modules 
Two heatsink retention modules (BKT-0012L) and four screws are included in the 
retail box.  Once installed, these are used to help attach the heatsinks to the CPUs.  
To install, align the module with the standoffs of the preinstalled CPU backplate and 
with the four feet on the module contacting 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-0012L is included for use with non-proprietary 
heatsinks only.  When installing proprietary heatsinks, only BKT-0011L (the CPU 
backplate) is needed.  The BKT-0012L retention module was designed to provide 
compatibility with clip-and-cam type heatsinks from third parties.
