Uvod
The SilverStone RM21-308 is a high-performance 2U rackmount server chassis designed for professional storage environments. It supports Micro-ATX motherboards and features eight hot-swappable drive bays compatible with 2.5-inch or 3.5-inch SAS/SATA drives. This manual provides detailed instructions for the installation, operation, and maintenance of your RM21-308 chassis.
Sigurnosne informacije
Please read and understand all safety precautions before installing or operating the chassis. Failure to do so may result in personal injury or damage to the equipment.
- Always disconnect the power cord from the power source before performing any installation or maintenance.
- Osigurajte ispravno uzemljenje kako biste spriječili strujni udar.
- Pažljivo rukujte unutrašnjim komponentama kako biste izbjegli oštećenja od statičkog elektriciteta. Koristite antistatičku narukvicu ako je dostupna.
- Do not block ventilation openings on the chassis. Adequate airflow is crucial for cooling.
- This chassis is designed for rackmount installation. Ensure the rack is stable and capable of supporting the total weight of the chassis and its components.

Setup
1. Montaža u rack
The RM21-308 chassis features auto-lock handles for easy integration into a 2U rack space. Optional sliding rail kits (e.g., SilverStone RMS04-20, sold separately) can be used for easier access.

2. Instalacija matične ploče
The chassis supports Micro-ATX motherboards. Install the motherboard using the provided standoffs and screws from the accessory kit. Ensure all I/O ports align correctly with the rear panel opening.
3. Instalacija napajanja
The RM21-308 accommodates most 2U single/redundant server power supplies or standard PS2 (ATX) power supplies. When selecting an ATX power supply, consider modular or semi-modular units to minimize cable clutter due to the chassis's depth. Ensure the power supply's fan orientation allows for proper airflow (front-to-back ventilation is ideal).
4. Instalacija pogona
The chassis features eight hot-swappable bays for 2.5-inch or 3.5-inch SAS/SATA drives. Additionally, there are internal mounting points for two 2.5-inch drives and one Slim ODD (12.7mm).
- Hot-Swap Bays: To install a drive, pull the handle on the drive tray to release it. Mount your 2.5-inch or 3.5-inch drive onto the tray using the appropriate screws from the accessory kit. Slide the tray back into the bay until it clicks securely into place.
- Internal Drives: Use the designated mounting points and screws for 2.5-inch drives and the Slim ODD.

5. Priključci ventilatora
The chassis includes three 80 x 15mm PWM fans. These fans are initially connected to the hard drive backplane. For optimal control and noise management, it is recommended to connect these fans to your motherboard's PWM fan headers. You may require fan extension cables (e.g., 26cm) due to the short length of the fan cables.

6. Backplane Connections
The backplane supports 8-port SAS/SATA drives and 12 Gb/s Mini-SAS SFF-8087. You will need:
- Two Mini SAS SFF-8087 cables: One for the top row of four drives and one for the bottom row of four drives. Connect these to your motherboard or SAS controller.
- Four Molex power cables: Connect these from your power supply to the backplane to provide power to the drives.

7. Priključci na prednjoj ploči
Connect the front panel USB 2.0 and USB 3.0 cables to the corresponding headers on your motherboard. Also, connect the power, reset, and LED indicator cables to the motherboard's front panel header.
Operating
Uključivanje/isključivanje
Press the power button on the front panel to turn the system on or off. Use the reset button for system restarts if necessary.
Diskovi koji se mogu brzo zamijeniti
The RM21-308 supports hot-swapping of drives. Ensure your operating system and SAS/SATA controller support hot-swapping before attempting to remove or insert drives while the system is powered on. Follow your operating system's guidelines for safely ejecting or adding drives.
Održavanje
Čišćenje
Regularly clean the chassis to ensure optimal airflow and prevent dust buildup. Use compressed air to clear dust from fans and ventilation grilles. For external surfaces, use a soft, damp tkanina.
Zamjena ventilatora
If a fan fails or becomes excessively noisy, it can be replaced. Disconnect power, open the chassis, and carefully replace the faulty fan with a compatible 80 x 15mm PWM fan. Note that space can be tight for standard 25mm thick fans.
Rješavanje problema
Ovaj odjeljak se bavi uobičajenim problemima s kojima se možete susresti.
- Glasna buka ventilatora: The included fans can be loud when connected directly to the backplane. Connect them to your motherboard's PWM headers and configure fan curves in your BIOS/UEFI for quieter operation.
- Diskovi nisu otkriveni: Ensure all Mini SAS SFF-8087 data cables and Molex power cables are securely connected to the backplane and your controller/power supply. Verify that drives are properly seated in their trays.
- Dimenzije šasije: Note that the actual depth of the chassis is approximately 18.9 inches, not 16.9 inches as sometimes listed. This is important for rack compatibility.
