Introduction The SJA1105SMBEVM (SJA1105S Mother Board Evaluation Module, see Fig 1) is designed for evaluating the capabilities of the SJA1105P/Q/R/S Automotive Ethernet switch family and the TJA1102 Automotive Ethernet PHYs, by developing and running customer software. Therefore, the board features the MPC5748G MCU with a rich set of peripherals for communication and automotive applications. It is designed to allow early adaptions of applications, like a X-to-Ethernet gateway, communication hub, etc. Fig 1. SJA1105SMBEVM board This user manual describes the board hardware and the software development environment to allow the user to quickly bring up a working system and to pave the way towards an own customized software, and in the end towards an all custom system. After the HW description the manual walks the user through the process to create the factory firmware starting at the supplied example project and describes the recommended SW development environment S32 Design Studio for Power as far as it is needed for the example project.

  • 8-Port Gigabit Switch
    GSW-0809 Version: 3 8-Port Gigabit Switch The LevelOne GSW-0809 Gigabit Ethernet Switch is designed for reliable high-performance networking. With its non-blocking switching fabric in full-duplex mode, this switch can deliver up to 2000Mbps per port, while the Store-and-Forward service brings low latency and error-free packet delivery. This highperformance Gigabit Ethernet switch is perfect for fulfilling the demands of online gaming and multimedia streaming. Moreover, this switch also supports IEEE 802.3az Energy Efficient Ethernet which helps reduce power consumption. Power Saving Features The GSW-0809supports IEEE 802.3az Energy Efficient Ethernet to provide power-saving benefits without compromising performance. One of the ways it does this is by automatically detecting the length of connected cables and can adjust power usage by saving energy on shorter cable connections. Internal Power With a built-in power supply, GSW-0809 is simple to install and use. No bulky adapters will hang on the wall and get in the way of your other electronic devices. Keep your desktop and computer area free from the clutter of cords! Easy to Use The GSW-0809 features plug-and-play for easy installation. No configuration is required. Autonegotiation on each port senses the link speed of a network device and adjusts for compatibility and optimal performance. Key Features - 8 Gigabit Ethernet ports - 10/100/1000Mbps wire speed transmission and reception - 9K jumbo frames to increase data transfer rates - Supports 8K MAC address auto-learning and auto-aging

  • Ethernet at New Speeds, Deterministic Networking, and Power Over Everything!
    Ethernet Evolving: Ethernet at New Speeds, Deterministic Networking, and Power over Everything! Dave Zacks Distinguished System Engineer @DaveZacks Peter Jones Principal Engineer @petergjones #NBASET BRKCRS-3900 #HighBitrate Ethernet Evolving: Ethernet at New Speeds, Deterministic Networking, and Power over Everything! BRKCRS-3900 – Session Overview We have a great session for you today … so sit back, buckle in, and let’s get started! Come to this session to get geared up on the latest developments in Ethernet for Campus and Branch networks. The Ethernet we all know and love is evolving at a rapid pace. With the release of MultiGigabit Ethernet on Cisco's latest Catalyst access switching platforms, you can connect new devices that support MultiGigabit connections at 2.5Gb/s and 5Gb/s over Cat5e/6 copper. No longer are 1Gbps and 10Gbps the only connectivity options – intermediate speeds are now possible. Cisco’s Multigigabit Technology is a key enabler for upcoming 802.11ac Wave 2 wireless deployments, where the Ethernet bandwidth required per AP exceeds 1Gb/s. Multigigabit switches also support other high-bandwidth devices in the Ethernet access layer without requiring expensive and time-consuming re-cabling for 10GBASE-T. We will talk about how Cisco MultiGigabit switches work, and how they will change your network. As well, we will discuss work being done in (and out of) the standards bodies to broaden the footprint for Ethernet, and enable the Internet of Everything. This includes additional Ethernet speeds, capabilities for deterministic networking functionality over an Ethernet infrastructure (precision timing, pre-emption, time scheduling, etc), and of course we need to provide more Power over Ethernet to more devices, in more places, than ever.

  • Chapter 10, Ethernet Operation
    CHAPTER10 Ethernet Operation This chapter describes the operation of the Cisco ONS 15600 SDH ASAP Ethernet card. For Ethernet card specifications, refer to Appendix A, “Hardware Specifications.” For step-by-step Ethernet card circuit configuration procedures, refer to the Cisco ONS 15600 SDH Procedure Guide. Refer to the Cisco ONS 15454 and Cisco ONS 15600 SDH TL1 Command Guide for TL1 provisioning commands. Chapter topics include: • 10.1 Any Service Any Port Card Application, page 10-1 • 10.2 Transport Functionality, page 10-2 • 10.3 Ethernet Rates and Mapping, page 10-4 • 10.4 Protocols over Ethernet, page 10-5 • 10.5 Buffering and Flow Control, page 10-6 • 10.6 Autonegotiation, page 10-7 • 10.7 Gigabit EtherChannel/IEEE 802.3ad Link Aggregation, page 10-8 10.1 Any Service Any Port Card Application The Any Service Any Port (ASAP) Carrier Card plugs into any of the eight available I/O slots for the ONS 15600 SDH. Each ASAP carrier card has four slots available for up to and including four ASAP Pluggable Input/output Modules (PIMs). There are four slots available on the PIM for Pluggable Port Modules (PPM), which are Small Form-factor Pluggable (SFP) optics. Four PPMs per ASAP PIM are allowed, which means that there can be as many as 16 PPM optical network interfaces for each ASAP carrier card. Each PPM can support any of the following single-rate SFP optics: • OC-3/STM-1 LR-2 • OC-12/STM-4 LR-2 • OC-48/STM-16 LR-2 Each of the PPM ports also supports the following multirate SFP optics: • OC-3/STM-1-SR-1 • OC-12/STM-4-SR-1 • OC-48/STM-16 IR-1 • GE LX Cisco ONS 15600 SDH Reference Manual, Releases 9.1 and 9.2.1 78-19884-01 10-1 Chapter 10 Ethernet Operation 10.2 Transport Functionality Each ASAP 4-port I/O (4PIO) and 1-port I/O (1PIO) PIM is hot-pluggable while other ports on other PIMs are functioning.
