4. Secure the SEC Cartridge: Secure the SEC cartridge in place by pushing the
SEC cartridge locks outward so that the lock shows through the retention
mechanism’s lock holes.
5. Secure the Heatsink: Install the heatsink support base into the motherboard.
This is not, however, necessary if you use a heatsink with fan (see next page).
The support base is necessary to secure the heatsink (without fan). Secure the
heatsink by sliding the heatsink support top bar into the bottom groove of the
heatsink until it locks into the heatsink support base posts.

6. Connect the Heat Sensor Cable to TRCPU (optional): If you purchased the
specially designed fan and thermal monitor heatsink, you can connect the heat
sensor cable to the motherboard’s CPU heat sensor connector (TRCPU).
