chassis, it is not a requirement to remove the QPI cables before removing the memory
board.
2. Remove the front bezel of the MAX5 by pressing in on the tab buttons on both sides of the
bezel. The bezel can be pulled away from the MAX5.
3. As shown in Figure 6-10, there are two blue release tabs that, when pressed to the sides
of the enclosure, allow you to pull out the cam levers that are used to begin to pull out the
memory tray.

4. You can pull the memory tray out about 30% before it stops. This design allows you to get
a better grip of the tray on either side and then use a finger to push in another set of blue
release tabs on either side of the tray, as shown in Figure 6-11.

5. Slide the memory tray completely out and place it on a flat work surface to work on the
memory.
Important: You must remove the ac power from both the server and the attached MAX5
before removing the memory tray. The FPGA of both the server and the MAX5 is still an
active component when the server is powered down but not removed from utility power.
FPGA components exist on both the server and the MAX5. Removing the memory board
with the ac power still active damages the FPGA components of both the server and the
MAX5.
For memory population order, see 4.9, "Storage" on page 145.
