BOXED PROCESSOR RETENTION
MECHANISM AND FAN/HEATSINK
SUPPORT
The Boxed processor requires a processor retention
mechanism as described in AP-588, Mechanical and
Assembly
Technology
Processors (Order Number 243333) to secure the
processor in Slot 1. The Boxed processor will not
ship with a retention mechanism. Motherboards
designed for use by system integrators should
include a retention mechanism and appropriate
installation instructions.
for
S.E.C.
Cartridge
The Boxed processor will ship with its own fan
heatsink support. The support differs from supports
for passive heatsinks. The Boxed processor
fan/heatsink support requires heatsink support holes
in the motherboard. Location and size of these holes
are give in Figure 45.
Any motherboard components placed in the area
beneath the fan/heatsink supports must recognize
the clearance (H) give in Table 28 below. Component
height restrictions for passive heatsink support
designs, as described in AP-588, Mechanical and
Assembly
Technology
Processors(Order Number 243333), still apply.
