Safety Precautions

The following precautions should be observed while handling the system:

- Place the system on a flat and stable surface.

- Do not place the system in environments subject to mist, smoke, vibration, excessive dust, salty or greasy air, or other corrosive gases and fumes.

- Do not drop or jolt the system.

- Do not use a power adapter other than the one enclosed with the system.

- Disconnect the power cord before performing any installation procedures on the system.

- Do not perform any maintenance with wet hands.

- Prevent foreign substances, such as water, other liquids or chemicals, from entering the system while performing installation procedures.

- Use a grounded wrist strap before handling system components such as CPU, Memory, HDD, expansion cards, etc.

- Place system components on a grounded anti-static pad or on the bed that came with the components whenever the components are separated from the system.

Assembly Overview
Heatsink Processor Processor Carrier Dust Cover Bolster Plate Assembly LGM4189 Back plate Drawings Shown for Example Only

Installing CPU & Heatsink

  1. Check the CPU and the processor carrier for their Pin 1 indicators.
  2. Align their Pin 1 indicators before inserting the CPU into the processor carrier. If installed properly, the CPU will snap into the side snap latches on the carrier and the carrier will latch firmly to the processor.

Pin-1 indicators

  1. Remove the protective film on the base of heatsink if any.
  2. Align Pin 1 indicator of processor carrier and the corner cutout of the heatsink. Gently press the heatsink down to engage the carrier's latching mechanism to the heatsink at four corners. A clicking sound will be heard when latched properly.
  3. Verify that the carrier and heatsink are firmly latched as one Processor Heatsink Module.
  4. Place the Processor Heatsink Module on top of the motherboard CPU socket with Pin 1 indicators aligned.
  5. Tighten all screws on the Processor Heatsink Module in diagonal sequences to

Installing Memory Modules

  1. Open the side clips to unlock the DIMM slot.
  2. Insert the DIMM vertically into the slot, ensuring that the off-center notch at the bottom aligns with the slot.
  3. Push the DIMM firmly into the slot until it clicks and the side clips automatically close.
  4. Verify that the side clips have securely locked the DIMM in place.

PCIe Add-in Card

Installing PCIe Add-in Card

  1. Loosen the screws on the riser bracket to remove the filler panels.
  2. Align the PCIe add-in card with the connector on the riser card, and insert it until it is fully seated.
  3. Tighten the screws to securely fix the PCIe add-in card in place.

Installing Riser Card Assembly

  1. Lower the riser card assembly down as shown in the image below.
  2. Insert the riser card assembly into the PCIe slot on the system board.
  3. Tighten the screws on the rear side of the system to secure the riser card assembly.

System Fan

The server system is equipped with 8 non-hot swappable system fans that measure 40 x 40 x 56mm, which provide primary airflow to maintain optimal cooling and prevent over heating.

The fan features include:

  • Tachometer on each fan allows BMC to monitor the system's status in real-time.
  • An integrated BMC firmware automatically adjusts fan speed based on the system's thermal status to maintain optimal performance.

Installing 1U Fan

  1. Lower the system fan until it seated firmly.
  2. Connect the fan cable to the system board.
  3. Note the fool-proof design on the connector before docking it.

Power Supply Unit (PSU)

The server system supports two power supplies that can be easily inserted and removed from the rear side of the system without the need for tools.

MSI S1201 - Power Supply Unit (PSU) - 1

Important

  • Both power supplies must be identical and both power cards should be connected.
  • Failing to connect both power supplies could result in CPU throttling.

Installing PSU

  1. Remove the PSU blank.
  2. Slide the PSU into the chassis bay until the release latch snaps into place.
  3. Connect the power cable to the PSU power outlet.
