Product Usage Instructions

CPU & Heatsink Installation:

1. Ensure the system is powered off and unplugged.
2. Locate the CPU socket on the motherboard.
3. Carefully align the CPU with the socket ensuring correct orientation.
4. Gently place the CPU into the socket and secure it in place according to the motherboard instructions.
5. Install the heatsink/fan on top of the CPU, ensuring proper thermal paste application.
6. Connect the heatsink fan to the designated header on the motherboard.

Front Panel Connector Installation:

1. Identify the front panel connectors labeled on the motherboard.
2. Refer to the user manual for the specific pin layout of each connector.
3. Connect the power LED, HDD activity LED, power button, reset button, and other front panel connectors accordingly.
4. Ensure a secure connection for each connector to avoid any malfunctions.

Memory Installation:

1. Power off the system and unplug all cables.
2. Locate the DDR5 DIMM slots on the motherboard.
3. If populating multiple DIMMs, refer to the motherboard manual for the optimal configuration.
4. Carefully insert the DDR5 DIMMs into the slots, ensuring they are fully seated.
5. Apply equal pressure on both ends of the DIMM to secure it in place.

FAQ

• What should I do if the system fails to boot after installing new memory?
  If the system fails to boot after installing new memory, try reseating the DIMMs or using only one DIMM at a time to identify any faulty modules. Ensure the memory modules are compatible with the motherboard specifications.
• How can I configure the UID LED button as a BMC reset button?
  To configure the UID LED button as a BMC reset button, use jumper JUID_SEL1 as directed in the manual. Change the jumper position to enable this functionality.
