The **CPCI-R6000** is a high-performance Rear Transition Module (RTM) designed specifically for CompactPCI (cPCI) systems. Its primary purpose is to extend the I/O capabilities of a front-loading CPU blade by routing signals through the backplane to the rear of the chassis. --- ### 1. Technical Specifications The following table outlines the key electronic components and hardware specifications typically found on the CPCI-R6000: | Component | Specification / Description | | :--- | :--- | | **Form Factor** | 6U CompactPCI Rear Transition Module (RTM) | | **Storage Interfaces** | Supports SATA/SAS and potentially PATA (IDE) interfaces | | **Network I/O** | Multiple RJ45 Gigabit Ethernet ports (typically 2x) | | **USB Support** | USB 2.0 / 3.0 Type-A connectors | | **Serial Ports** | RS-232/422/485 via DB9 or RJ45 headers | | **Video Output** | VGA or DVI-D ports for display output | | **Backplane Connector** | High-density J3/J4/J5 connectors for signal routing | --- ### 2. Key Electronic Features #### A. Signal Routing and Integrity The CPCI-R6000 acts as a bridge. It does not usually contain a standalone CPU; instead, it utilizes passive and active signal conditioning components to ensure that high-speed signals (like PCIe or SATA) traveling from the front board through the backplane maintain integrity. #### B. Hot-Swap Support The module is designed with electronic circuitry that supports **Hot-Swapping**. This involves: * **Pre-charge pins:** To prevent arc discharge during insertion. * **Handle switch:** A microswitch that alerts the system software to prepare for the removal of the module. #### C. Power Management While the main power is drawn from the cPCI backplane, the R6000 includes local voltage regulators and decoupling capacitors to filter noise and provide stable power to the onboard I/O controllers and storage devices. --- ### 3. Connection Layout (Typical) The board layout is optimized for high-density I/O. Below is a representation of the electronic interfaces provided at the rear panel: 1. **Ethernet Transceivers:** Magnetic isolation modules located near the RJ45 ports to protect the system from external electrical surges. 2. **Storage Headers:** Internal SATA connectors used for mounting 2.5" SSDs or HDDs directly onto the RTM. 3. **Super I/O Controller:** Manages legacy ports such as the PS/2 keyboard/mouse or serial COM ports. --- ### 4. Application Use Case The CPCI-R6000 is primarily used in **industrial automation, telecommunications, and military systems** where cabling needs to be managed at the rear of the rack to allow for quick replacement of the front-side processing blades without disconnecting peripheral cables.
