3. Setup Instructions

3.1 Safety Guidelines

Always disconnect the power cord from the wall outlet before performing any installation or maintenance. Wear an anti-static wrist strap to prevent electrostatic discharge (ESD) damage to components. Handle all components with care.

3.2 Unpacking the Chassis

Carefully remove the RM400 chassis from its packaging. Inspect for any signs of damage during transit. Retain the packaging for future transport or storage.

3.3 Motherboard Installation

1. Remove the top cover of the chassis by unscrewing the retaining screws.
2. Install the appropriate standoffs for your motherboard form factor (CEB, ATX, mATX, Mitx) onto the motherboard tray.
3. Carefully place the motherboard onto the standoffs, aligning the screw holes.
4. Secure the motherboard with screws.

3.4 Power Supply Installation

The RM400 supports ATX (PS2) or Mini redundant power supplies up to 160mm in depth. Install the power supply into the designated rear mount area and secure it with screws.

3.5 Drive Installation (5.25" Bays)

The chassis features three 5.25-inch drive bays. To access these bays, open the front security door.

4. Operating Instructions

4.1 Powering On/Off

After all components are installed and cables connected, connect the power cord to the power supply and a wall outlet. Press the power button on the front panel to turn on the system. To turn off, use the operating system's shutdown procedure or press and hold the power button for several seconds.

4.2 Front Panel I/O

The front panel provides convenient access to USB 3.1 Gen 1 ports and power/reset buttons. The front door can be locked using the provided key to prevent unauthorized access to the drive bays and front I/O.

5. Maintenance

5.1 Cleaning

Regularly clean the chassis to ensure optimal airflow and prevent dust buildup. Use compressed air to clear dust from fans and vents. The front panel features mesh areas that act as dust filters; these should be cleaned periodically.

5.2 Fan Inspection and Replacement

Periodically inspect the included 120mm and 80mm PWM fans for proper operation. If a fan becomes noisy or stops working, it should be replaced to maintain adequate cooling.

6. Troubleshooting

6.1 System Not Powering On

• Verify the power cord is securely connected to both the power supply and the wall outlet.
• Ensure the power supply switch is in the 'ON' position.
• Check all internal power connections, especially the 24-pin ATX and 8-pin CPU power cables to the motherboard.
• Confirm the front panel power button cable is correctly connected to the motherboard header.

6.2 Overheating Issues

• Ensure all case fans are operating correctly and are not obstructed.
• Clean any dust buildup from fans, heatsinks, and air intakes.
• Verify proper thermal paste application on the CPU cooler.
• Ensure adequate airflow within the rack environment.

6.3 Component Fit Issues

If a component does not fit, double-check its dimensions against the chassis specifications. For example, ensure your power supply is within the 160mm depth limit and that expansion cards are standard profile.
