#### Memory recommendations when using a GPU
When a GPU is installed in the system, it is recommended that the minimum system memory should be at least 1.5 times the total GPU memory. For superior performance and to accommodate future workloads, it is strongly recommended that the system memory be 2.0 times the total GPU memory. Failure to meet these memory requirements may result in degraded performance or unexpected application behavior.

### 2.5 - Block Diagram
## 3 - Installation & Mechanical
### 3.1 - Internal Access
Please follow the instructions below to open the system and service the specified component or device.
Important Notes:
* Before removing the top cover, the system should be powered off and the power cord unplugged.
* The system must be operated with the chassis top cover installed to ensure proper cooling.
#### Removing the Server Top Cover
**Step 1**: Remove the screws that secure the top cover to the chassis.\
**Step 2**: Push the top cover toward the rear of the chassis to remove the cover from the locked position.\
**Step 3**: Lift up and remove the top cover.
#### Installing the Server Top Cover
**Step 1**: Lower the top cover on the chassis, making sure the side latches align with the cutouts.\
**Step 2**: Slide the top cover toward the front.
**Step 3**: Secure the top cover with the screws.
#### 3.5” Hard Drive
#### Removing the 3.5” Hard Drive Carrier
**Step 1**: Release the screws that secure the hard drive carrier to the chassis.\
**Step 2**: Lift up and remove the carrier.
#### Installing a 3.5” Hard Drive into the Hard Drive Carrier
**Step 1**: Place the 3.5" HDD into the carrier with the printed circuit board side facing down. Carefully align the mounting holes in the hard drive and the carrier.\
**Step 2**: Secure the hard drive using the screws.\
**Step 3**: Place the drive carrier, with a 3.5" HDD installed, back to the chassis with screw holes aligned. **Step 4**: Secure it to the chassis with screws.
#### 2.5” Hard Drive
#### Removing 2.5” Hard Drive Trays
**Step 1**: Press the locking lever latch on the drive tray to unlock the retention lever.\
**Step 2**: Rotate the lever out and away from the module bay and pull the hard drive out of the HDD tray
#### Installing a 2.5” Hard Drive to the Hard Drive Tray
**Step 1**: Place a 2.5" HDD into the bracket with the printed circuit board side facing down.\
**Step 2**: Slide the drive tray into the HDD bay until the drive is fully seated.\
**Step 3**: Push in the locking lever to lock the HDD tray into place.
#### System Fan
System fans are required for the cooling in the system. Please make sure that the chassis top cover is properly installed in order for the cooling air to circulate properly through the chassis and cool the system and components.
If a fan fails, the ambient air temperature in the chassis will rise. Replace any failed fan immediately.
#### Replacing the Simple-Swap Fan
**Step 1**: Remove the cover. Unplug the fan connector and remove the failed fan.\
**Step 2**: Align the mounting holes on the fan bar with the fan mounts on the replacement fan.\
**Step 3**: Gently place the fan on the fan bar. Make sure the fan is well seated.
**Step 4**: Plug the fan wires into the correct fan header.
#### Power Supply
This system has a single 315 watt power supply and can accommodate one AC power supply in the bay at the rear of the chassis. There is no power supply redundancy so if the power supply unit fails, the system will shut down and the user will need to replace the power supply unit.
#### Remove/Replace CPU
Images below are illustrative and may not accurately depict the CPU heatsink
**To remove the CPU**:
**Step 1**: Loosen the 4 corner fasteners on the cooler in a star pattern to ensure even pressure release.
**Step 2**: Gently pull the CPU cooler up by the edges.
**Step 3**: Once the cooler is removed, remove any thermal grease from the CPU.
**Step 4**: Release the CPU latch lever pushing the end of the lever down and away from the CPU
**Step 5**: Lift the lever to release the CPU bracket, then lift the bracket to expose the CPU and socket
**Step 6**: Remove the CPU from the CPU socket by lifting the latch lever.
**Step 7**: If not immediately reinstalling a CPU, fit a socket cover into the CPU socket to protect the pins. Close and secure the CPU bracket and lever. If immediately replacing a CPU skip to step 3 below.
**To replace the CPU**:
**Step 1**: Release the CPU latch lever pushing the end of the lever down and away from the CPU.
**Step 2**: Lift the lever to release the CPU bracket, then lift the bracket to expose the CPU and socket.
**Step 3**: Line the CPU up on the CPU socket using the golden triangle found on the corner of the CPU and additionally using the notches found on the CPU and CPU socket.
**Step 4**: Gently place the CPU into the socket.
\
**Step 5**: Close the CPU bracket over the CPU. Close the latch lever and secure it by pressing down and towards the CPU. Ensure the lever latches under hook and remains secure when pressure is released.
**Step 6**: Apply thermal grease to the CPU surface.
**Step 7**: Install the heatsink using the four screws around the CPU socket.
#### Installing CPU Heatsink
After the CPU is installed into the system, a heatsink will need to be installed to dissipate heat. Thermal Paste comes pre-applied to the heatsink.
**Step 1**: Remove 4x screws
**Step 2**: Remove the brackets from the motherboard.
**Step 3**: Attached the Heatsink provided with the system onto the motherboard.
#### Remove/Replace DIMMS
**To remove DIMMS:**
**Step 1**: Press down on the latches on the DIMM slots on the motherboard until they are tilted away from the DIMM.
**Step 2**: Gently pull the DIMM out of the slot.
**To replace DIMMS:**
**Step 1**: Press down on the latches on each side of the DIMM slot on the motherboard until they are tilted away from the DIMM slot.
**Step 2**: Line up the notch in the DIMM with the notch in the slot to ensure the DIMM goes in correctly.
**Step 3**: Gently press the DIMM into the slot until an audible click is heard which indicates the latches have been engaged and are holding the DIMM in place.
