EKF CCL-CAPELLA Mezzanine I/O Expansion Board Quad Gigabit Ethernet Networking Controller

Available as a mezzanine add-on expansion board to the CCG-RUMBA and successor CPU cards, the CCL-CAPELLA provides a number of additional I/O functions. First of all, the CCLCAPELLA is a powerful Ethernet networking machine, with up to four independent low power Gigabit Ethernet controllers. Each GbE port can be individually routed either to a front panel jack, or the rear I/O connector, by software controlled switches (BIOS setup). The additional SATA/PATA controllers are useful for attachment of mass-storage devices, either on-board mounted, or externally (by cable or via rear I/O). The optional FireWire ports are practical e.g. for vision systems with mixed 1394a and GbE type cameras, and is especially useful for quality-ofservice demanding and isochronous applications. Furthermore the CCL-CAPELLA is equipped with a SIO, which provides legacy I/O ports, such as serial, parallel, KB/MS (all available across rear I/O). A secondary Firmware Hub can be configured as alternate- or backup-BIOS. Another option available is the Trusted Platform Module according to TPM 1.2 for safety critical applications.The CCL-CAPELLA will be attached on top of the CPU carrier board, and typically shares its front panel with the host carrier (usually 8HP front panel width in total). Interconnection between the CCL-CAPELLA I/O module and the CPU carrier board is achieved by two expansion connectors, which comprise the PCIe (PCI Express x 4) and LPC (Low Pin Count) interfaces. As an option, the CCL-CAPELLA is available with a mezzanine module (C20-SATA), which accommodates one or two 2.5-inch SATA hard disk drives (RAID option). Additionally, a CompactFlash card adapter (C17-CFA) can be mounted on bottom of the CCL-CAPELLA. As an alternative, a top mount 1.8-inch storage module (C30-PATA) is available, for HDD or SSD usage. As another option, up to two USB Flash drive modules can be accommodated, top and bottom. The CCL-CAPELLA is best suited for demanding networking I/O applications, e.g. routers, gateways, vision systems, or network fabric. Maximum throughput is achieved through PCI Express technology. Combined with the two GbE ports available on the CPU carrier board, six individual networking interfaces altogether are provided for high performance Ethernet communicationThe CCL-CAPELLA communicates by means of two bottom mount expansion connectors with the host CPU: P-PCIE (PCI Express x 4), and P-EXP (multi-function I/F such as LPC, USB, SMB). The PCI Express interface (connector P-PCIE) is comprised of 4 PCIe lanes, which are derived from the ICH (southbridge chip) on the CPU carrier board. All 4 lanes are routed to the primary port of a 12-port 12-lane PCI Express packet switch, which is the main component of the CCL-CAPELLA. Connector P-EXP combines several other southbridge data channels: The LPC (Low Pin Count) is a multiplexed ISA bus, e.g. enabling the super-I/O (SIO) controller chip to emulate the legacy I/O interfaces; among these are the classic parallel (printer) and serial (COM) ports. Two USB channels are provided, either for the optional USB SSD headers, or for rear I/O via the J2 connectorThe Trusted Platform Module is an optionally available cryptographic chip, which provides a comprehensive hardware and software solution for safer computing. Conforming to the TPM1.2 standard of the TCG, the TPM is comprised of a 16-bit security controller and additional hardware e.g. to generate 2048 bit RSA keys and true random numbers, thus meeting the highest industry rating for digital security. The CCL-CAPELLA fits on the top side of the CPU board, which is on the right side when viewing the common front panel. A suitable backplane provides its CPCI slots beginning with the CPU carrier board (CPCI system slot) from right to left. The CPCI system must provide additional mounting space to the right side for the CCL-CAPELLA. In addition, a single slot rear I/O backplane would be needed for rear I/O usage, and a custom specific rear I/O transition module
