The **M2AS1-6342-R/CE** is a specialized electronic component, specifically a **Mini-SAS (Serial Attached SCSI) Internal Cable Assembly**. These parts are critical in high-speed data environments like servers, data centers, and high-performance workstations. --- ## 1. Technical Specifications This component is designed to bridge the gap between storage controllers (HBAs/RAID cards) and backplanes or hard drives. | Feature | Specification | | :--- | :--- | | **Connector Type A** | SFF-8087 (Internal Mini-SAS 36-pin) | | **Connector Type B** | SFF-8087 (Internal Mini-SAS 36-pin) | | **Data Rate** | 6.0 Gbps (per lane) | | **Configuration** | 4-lane (4i) design | | **Cable Length** | Typically 0.5m to 1m (Standard for R/CE series) | | **Impedance** | 100 Ohms | | **Protocol Support** | SAS 2.1 and SATA III | --- ## 2. Key Electronic Characteristics ### High-Speed Signal Integrity The "R" in the part number often denotes **RoHS compliance**, while the "CE" indicates certification for European safety and electromagnetic interference standards. The internal wiring is shielded to prevent **Crosstalk** and **Electromagnetic Interference (EMI)**, which is vital when transmitting data at 6Gbps per lane. ### Physical Architecture * **Sidebands:** The cable includes dedicated wires for sideband signaling (SGPIO), allowing the controller to communicate with the backplane for "Enclosure Management" (e.g., controlling drive status LEDs). * **Latch Mechanism:** The SFF-8087 connectors feature a mechanical friction or push-button latch to ensure the connection does not vibrate loose in server chassis. --- ## 3. Common Applications 1. **Server Backplanes:** Connecting a motherboard's integrated SAS port to a drive cage. 2. **RAID Cards:** Linking a PCIe RAID controller (like LSI or Adaptec) to multiple SATA/SAS drives. 3. **JBOD Enclosures:** Internal routing within "Just a Bunch of Disks" expansion units. ---
