2.1. Sliding Rail Installation

The chassis includes a set of 20" sliding rails for easy installation into a 600mm deep rack cabinet. Follow these steps to install the rails:

1. Separate the inner rail from the outer rail. The inner rail attaches to the chassis, and the outer rail attaches to the rack.
2. Attach the inner rails to the sides of the chassis using the provided short screws. Ensure the holes are aligned and screws are tightened securely.
3. Attach the outer rails to the rack cabinet. The rails are designed to be adjustable. Use the longer screws for the cabinet. Ensure both front and back ends of the outer rails are securely fastened to the rack posts.
4. Carefully slide the chassis with the inner rails into the outer rails mounted on the rack. Ensure proper alignment and that the locking mechanisms engage.

2.2. Instalación do disco duro (SSD/HDD de 2.5")

To install 2.5-inch hard drives or SSDs into the hot-swap trays:

1. Pull out an empty hot-swap drive tray from the front of the chassis.
2. Place the 2.5" drive into the tray. Align the screw holes on the drive with the corresponding holes on the tray.
3. Secure the drive to the tray using the provided screws.
4. Slide the populated drive tray back into the chassis until it clicks into place.

2.3. Conexións por cable

Proper cable management is crucial for optimal performance and airflow. The chassis includes Mini SAS to SATA cables for connecting the hot-swap backplane to your motherboard or HBA.

1. Connect the Mini SAS 36pin (SFF-8087) male end of the provided cables to the backplane connectors within the chassis.
2. Connect the 4x SATA 7pin female ends of each cable to the SATA ports on your motherboard or Host Bus Adapter (HBA). Ensure each SATA connector is securely attached to a drive.
3. Connect the power supply cables to the motherboard, drives, and fans as required.

4. Mantemento

Regular maintenance ensures the longevity and optimal performance of your RackChoice server chassis.

• Eliminación de po: Periodically clean the chassis interior and fan filters (if applicable) to prevent dust buildup, which can impede airflow and cause overheating. Use compressed air or a soft brush.
• Inspección do ventilador: Check the 80mm middle fans for proper operation. Ensure they are spinning freely and quietly. Replace any noisy or malfunctioning fans.
• Xestión de cables Verify that all internal cables (SATA, power, Mini SAS) are securely connected and neatly routed to avoid obstructing airflow or interfering with other components.
• Drive Bay Check: Ensure hot-swap drive trays are fully seated and locked.

5 Solución de problemas

This section addresses common issues you might encounter with your RackChoice 2U server chassis.

• Ruído forte do ventilador: The included 80mm fans are designed for high airflow. If noise is excessive, consider replacing them with quieter PWM fans and connecting them to a motherboard with PWM control. Ensure no cables are obstructing fan blades.
• Difficulty with Sliding Rail Installation: Ensure the inner and outer rails are correctly separated and aligned. Refer to Video 1 for detailed installation steps. If the rails bind, check for proper screw placement and ensure they are not overtightened.
• SATA Port Clearance Issues (Micro-ATX Motherboards): Some Micro-ATX motherboards with 90-degree SATA ports may have clearance issues with the chassis's internal structure. Consider using 180-degree SATA male-to-female connectors or alternative SATA cables if this occurs.
• Front Panel Power Button Stuck: If the power button is stuck, gently inspect the plastic cover housing the buttons and USB port. Ensure no debris is causing obstruction. In some cases, minor adjustment or removal of specific screws from the plastic cover might be necessary to free the button.
• No Hard Drive Activity/Detection: Verify that all Mini SAS to SATA cables are securely connected to both the backplane and the motherboard/HBA. Ensure drives are properly seated in their hot-swap trays. Check power connections to the drives.
