1.2 Server Introduction
This is an isometric view of E8020 server. There are some PCIe slot/Drive bays/IO
connections in the front depending on different configurations. On the rear end,
there is a floating connector that fits into bus bar providing power to this sled.
There are sharp edges on the metal parts. This is generic to the low-
cost OCP design. Be sure to wear gloves when you
assemble/disassemble any mechanical components. For example,
PCIe bracket, PCIe cards and installing cables…etc.

2.2 Installing Motherboard Components
This section describes how to install components on to the mainboard, including
CPUs, memory modules, adapter Card, Drive and Add On cards.
2.2.1 Removing the Chassis Cover
Follow these instructions to remove chassis cover.
⚫Push the top cover in the arrow direction.

9
2.2.2 Installing the CPU and Heatsink
Follow the steps below to install the processor and heatsink.
Install the CPU
A. Remove the PnP Cover Cap
un-thread (counter-clockwise direction) all the screws (shown above in red circles) on the top of the
Force Frame using 3-2-1 sequence (i.e. un-thread Screw #3 in its entirety first, followed by Screw #2,
and lastly Screw #1) . Screw numbers are marked next to the screws on the Force Frame.
The spring loaded Force Frame will raise up to beyond the vertical position (105 degrees) on its pivot
hinge after the last Screw #1 is completely un-threaded. Hold and rotate the Force Frame until it has
come to the final “open” position before releasing finger grasp on the Force Frame.
As can be seen above, both the PnP Cover Cap and the External Cap co-exist during the SAM
installation to protect the contacts in the Socket Housing from damage.

10
Lift the Rail Frame by griping the lift tabs near the front end of the Rail Frame.
Note that the External Cap is pre-installed in the Rail Frame when shipped by the socket suppliers.
Caution: The Rail Frame is spring loaded, thus please hold on to the Rail Frame as it is dis-engaged
from the Socket Housing.
While holding the Rail Frame, slowly rotate the Rail Frame to the vertical position.
Do not release the Rail Frame until it is in the vertical position since the spring force for the Rail Frame
is optimized for the heavier CPU package. The lighter External Cap currently in the Rail Frame can
produce an abrupt swinging motion.

11
The Rail Frame will come to a stop in the vertical position for subsequent operations.
Note: Do not remove the PnP Cover Cap at this point of the installation procedure to prevent
accidental contact damage in the subsequent steps.

12
Remove the External Cap by pulling upwards on the handle of the External Cap to clear the rail guides
on the Rail Frame.
CPU Package is shipped from AMD factory with the blue Carrier Frame pre-assembled:
Upper picture -Top view showing the lid side of the Carrier Frame/CPU Package assembly.
Lower picture -Bottom view showing the land pad side of the Carrier Frame/CPU Package assembly.

13
Grip the handle of the Carrier Frame to lift up the Carrier Frame/CPU Package assembly from the CPU
Package shipping tray.
While gripping the handle of the Carrier Frame, align the flange features on the Carrier Frame with the
rail guides on the Rail Frame and slide the Carrier Frame downwards.
Check to ensure that the flange features on the Carrier Frame are inserted into the rail guides of the
Rail Frame.

14
Slide the Carrier Frame downwards until it bottoms out and locks with the Rail Frame.
The user will be able to feel the locking action as the Carrier Frame mates with the locking features on
the Rail Frame.
The Carrier Frame/CPU Package assembly is now completely loaded onto the Rail Frame.
The PnP Cover Cap can now be removed. Grip the two lift tabs marked “REMOVE” at the middle of the
long sides of the PnP Cover Cap and pull vertically upwards to remove the PnP Cover Cap from the
Socket Housing.
Be very careful not to drop the PnP Cover Cap into the exposed contact field during the removal
process.

15
Exposed socket contacts are extremely vulnerable and can be easily damaged. Do not touch the
contacts. Use extreme caution to not drop the PnP Cover or any thing else into the exposed contact
field in the Socket Housing.
The PnP Cover Cap removal procedure is applicable for the first CPU Package insertion only. The PnP
Cover Cap is not replaced onto the Socket Housing after the first CPU Package removal to avoid the risk
of damaging the contacts during PnP Cover Cap replacement procedure. Henceforth, the contacts in
the Socket Housing are protected by the External Cap.
Grip the lift tabs at the top of the Rail Frame and rotate the Rail Frame with locked Carrier Frame/CPU
Package assembly downwards onto the Socket Housing.
