iStarUSA M-140-JB Drive Enclosure — 1U Rack-Mountable Trayless JBOD

The iStarUSA M-140-JB is a compact, high-performance 1U rack-mountable drive enclosure designed for demanding data storage environments. Featuring trayless, hot-swappable 3.5" bays, a built-in 150W open-frame power supply, and a backplane with four peer-to-peer SATA ports, this JBOD chassis delivers reliable, scalable storage for servers, media editing suites, backups, and data centers. Engineered for quick drive replacements and minimal downtime, the M-140-JB blends rugged durability with streamlined efficiency to maximize rack space and storage density while keeping maintenance simple and costs under control.

• Trayless, hot-swappable 3.5" bays: The M-140-JB eliminates drive trays for faster installation and replacement of drives. Hot-swappable bays mean you can swap drives without powering down the system, reducing downtime during maintenance or capacity upgrades.
• 1U rack-mountable design: A compact, space-saving chassis that fits neatly into standard 19" racks, making it ideal for data centers, server rooms, and busy workstations where rack space is at a premium.
• Built-in 150W open-frame power supply: A robust, integrated power solution simplifies cabling and reduces clutter, delivering reliable power for multiple 3.5" drives while maintaining efficient thermal performance in rack environments.
• Four backplane SATA ports (peer-to-peer): The backplane provides four SATA connections, enabling flexible drive configurations and direct host connections for straightforward storage expansion and JBOD setups.
• Durable black chassis for professional deployments: A sturdy metal construction in a neutral black finish, designed to withstand the rigors of server rooms and mounting environments while maintaining a sleek, professional appearance.

How to install iStarUSA M-140-JB Drive Enclosure

Installing the iStarUSA M-140-JB is straightforward and designed to minimize downtime. Follow these general steps to integrate the enclosure into your storage stack:

• Step 1: Prepare your rack space. Use appropriate rails and mounting hardware to securely install the M-140-JB into a standard 19" rack. Ensure there is adequate clearance for cooling and cable management, and verify that your rack has sufficient power outlets and ventilation.
• Step 2: Mount the enclosure. Slide the chassis into the rack rails and fasten it with screws or cage nuts as required by your rack system. Confirm the enclosure is level and securely anchored to prevent vibration during operation.
• Step 3: Install drives. With the enclosure powered off, insert your standard 3.5" SATA drives directly into the trayless bays. Push the drives firmly until they seat and the hot-swap mechanism latches securely. This trayless design simplifies drive insertion and removal while maintaining proper alignment with the backplane.
• Step 4: Connect power and data cables. Attach the built-in 150W power supply to a reliable power source. Connect SATA data cables from the host controller or motherboard to the backplane’s SATA ports. Route cables neatly to promote airflow and ease future maintenance.
• Step 5: Configure in the host system. Power on the server or storage array and enter your operating system’s disk management utility to recognize the new drives. Configure JBOD, span, or RAID arrays as needed, depending on your storage requirements and controller capabilities. Validate drive visibility and performance before placing the system into production.
• Step 6: Verify cooling and airflow. Ensure adequate airflow over the front-to-back path to maintain drive temperatures within safe operating ranges. If needed, adjust rack fans or placement to optimize cooling for sustained performance.
