1. Einleitung
The Inter-Tech ST-5255 is a versatile 5-way removable frame designed to accommodate up to five 2.5-inch or 3.5-inch hard drives within three standard 5.25-inch drive bays of a computer chassis. This unit facilitates easy installation and removal of storage devices, supporting data transfer speeds up to 6Gb/s (SATA III or SAS). It is an ideal solution for expanding storage capacity or implementing RAID configurations (requires a separate RAID controller).
2. Sicherheitshinweise
- Vor dem Einbau oder Ausbau von internen Komponenten muss der Computer immer vom Stromnetz getrennt werden.
- Handle hard drives and the frame with care to prevent damage from electrostatic discharge. Use an anti-static wrist strap if available.
- Sorgen Sie für ausreichende Belüftung rund um das Computergehäuse, um eine Überhitzung zu vermeiden.
- Setzen Sie das Gerät keiner Feuchtigkeit oder extremen Temperaturen aus.
- Only use compatible power and data cables.
3. Packungsinhalt

4. Einrichtung und Installation
4.1. Preparing the Computer Chassis
- Schalten Sie Ihren Computer aus und trennen Sie das Netzkabel.
- Open the computer chassis to access the internal drive bays.
- Identify three consecutive empty 5.25-inch drive bays. Remove any front bezels or covers from these bays.
4.2. Installing the Removable Frame
Slide the ST-5255 frame into the three available 5.25-inch bays from the front of the chassis. Secure the frame using the provided mounting screws on both sides of the chassis. Ensure the frame is firmly seated.

4.3. Installing Hard Drives into Trays
Each hard drive tray supports one 2.5-inch or 3.5-inch hard drive.
- Pull out an empty drive tray from the ST-5255 frame by pressing the release lever and pulling the handle.
- Place your 2.5-inch or 3.5-inch hard drive into the tray. Align the screw holes on the drive with those on the tray.
- Secure the hard drive to the tray using appropriate screws (not included with the frame, typically provided with hard drives).
- Slide the populated tray back into an empty slot in the ST-5255 frame until it clicks into place.

4.4. Verbindungskabel
The ST-5255 requires five individual S-ATA data cables (one for each drive bay) and two 4-pin Molex power connectors.
- Connect one end of each S-ATA data cable to the corresponding port on the rear of the ST-5255 frame.
- Connect the other end of each S-ATA data cable to an available S-ATA port on your motherboard or RAID controller.
- Connect two 4-pin Molex power connectors from your power supply unit (PSU) to the power ports on the rear of the ST-5255 frame.

4.5. RAID Configuration (Optional)
For RAID functionality, a separate RAID controller is required. The ST-5255 itself does not provide RAID capabilities. Refer to your RAID controller's manual for specific setup instructions.
Important Note for Intel Onboard S-ATA Controllers: When using this product with Intel Onboard S-ATA controllers, the controller must be explicitly set to "hot plug/external port" in RAID mode or the individual ports of the controller. If these settings are not available, error-free operation, especially hot-swapping, may only be possible with an additional S-ATA controller.
5. Bedienungsanleitung
5.1. Einschalten
After completing all connections, close your computer chassis, reconnect the power cable, and power on your computer. The installed hard drives should be detected by your operating system or RAID controller.
5.2. Hot-Swapping Drives
The ST-5255 supports hot-swapping of hard drives, provided your motherboard or RAID controller also supports this feature and is configured correctly (refer to section 4.5). To hot-swap a drive:
- Safely eject or unmount the drive from your operating system.
- Press the release lever on the desired drive bay and pull the handle to remove the drive tray.
- Replace the old drive with a new one in the tray (refer to section 4.3).
- Slide the new drive tray back into the bay until it locks. The new drive should be detected by the system.
5.3. LED-Anzeigen
Each drive bay typically features LED indicators:
- Betriebs-/Aktivitäts-LED: Usually illuminates when a drive is powered on and blinks during data access.

6. Wartung
- Reinigung: Periodically clean the exterior of the frame and the fan grille to prevent dust buildup, which can impede airflow and cooling performance. Use a soft, dry cloth. For internal cleaning, disconnect power and use compressed air.
- Lüfterinspektion: Check the integrated 80mm fan periodically for proper operation. If the fan becomes noisy or stops working, consider replacing it to ensure adequate cooling for your hard drives.
7. Fehlerbehebung
- Nicht erkannte Laufwerke:
- Ensure all S-ATA data cables are securely connected to both the frame and the motherboard/controller.
- Verify that both 4-pin Molex power connectors are firmly attached to the frame.
- Check if the hard drives are properly seated and secured within their trays.
- Confirm that your motherboard's BIOS/UEFI settings or RAID controller configuration recognize the S-ATA ports.
- If using an Intel Onboard S-ATA controller, ensure "hot plug/external port" settings are enabled if applicable (refer to section 4.5).
- Überhitzungsprobleme:
- Ensure the integrated 80mm fan is operating correctly.
- Check for dust buildup on the fan and vents and clean if necessary.
- Verify that your computer chassis has adequate airflow.
- Langsame Datenübertragung:
- Ensure you are using S-ATA III compatible cables and your motherboard/controller supports 6Gb/s speeds.
- Überprüfen Sie den Zustand Ihrer Festplatten.
