Supermicro CBL-SAST-1276F-100 SAS cable 0.76 m Slimline x8 to Slimline x4

The Supermicro CBL-SAST-1276F-100 SAS cable 0.76 m Slimline x8 to Slimline x4 is a compact internal storage interconnect designed for server and storage chassis. With a 0.76 meter length it provides a reliable connection between a Slimline x8 port and two Slimline x4 ports, supporting high-speed Serial Attached SCSI (SAS) links for multi-drive configurations. The cable is intended for internal use in rackmount and tower systems where short, direct connections between backplanes, RAID controllers and drive assemblies are required.

Advantages

The cable delivers a stable physical connection with connectors sized to fit Slimline SAS interfaces, minimizing signal loss and maintaining data integrity across short internal runs. Its dual Slimline x4 output allows one x8 source to feed two separate channels, simplifying cabling for multi-bay arrays. The compact 0.76 m length reduces cable clutter inside server enclosures and helps maintain airflow. Materials and termination are chosen to withstand repeated insertion cycles typical in maintenance and drive replacement operations.

Suitable for

• Connecting a Slimline x8 controller or backplane to multiple Slimline x4 drive ports
• Internal cabling in rackmount servers and storage arrays
• Short-distance connections between RAID controllers and disk backplanes
• Server maintenance scenarios requiring modular, replaceable cabling

Key specifications

• Cable length: 0.76 meters
• Connector configuration: one Slimline x8 at one end, two Slimline x4 at the other
• Interface type: Serial Attached SCSI (SAS)
• Intended use: internal data/storage interconnect
• Design: compact, low-profile Slimline connectors for dense drive bays

How to use

Power down the system and follow ESD precautions before connecting the cable. Insert the Slimline x8 connector into the matching x8 port on the controller or backplane until it seats firmly, then attach the two Slimline x4 connectors to the corresponding drive or backplane ports. Ensure connectors are aligned with their keyed guides to avoid damage. After connections are secure, verify that drives and controllers are recognized by the system firmware or operating system and restore power.

Usage recommendations

Use this cable only for internal server and storage connections; avoid bending the cable sharply or routing it near high-heat components. For reliable operation, keep cable runs short and secured to prevent movement during maintenance. Replace the cable if connectors show visible wear or if intermittent errors appear in storage diagnostics.
