CPU Installation Procedures
All CPU sockets must be empty before proceeding. Use the following procedure to install new
CPUs.
CAUTION: Avoid removing any VRMs to connect the CPU power pod and Turbocooler cables
into the cell board connectors.
NOTE: CPU load order must be maintained when adding CPUs to the cell board. Always load
CPU socket 0 first.
To install new processors, follow these steps:
1. If the CPU 0 ZIF socket is not exposed, remove the ZIF socket pin cover from the cell board.
2. Ensure that the cell board ZIF socket is in the “unlocked” position.
3. Remove the CPU module from its packaging.
4. Remove the CPU module pin cover and inspect the pins for any damage.
NOTE: Carefully remove the pin cover to avoid any damage to the pins.
5. Slide the load screw sequencer toward the turbocooler to expose the ZIF socket peep hole
through the turbocooler.
6. Rotate the fan to expose the ZIF socket peep hole location. See Figure 6-35.

7. Lower the CPU module into the ZIF socket making sure it is held level to the board, until
the pins on the CPU engage with the ZIF socket.
