  • Page 13: Advanced Lan Bypass Hardware Architecture Overview

    Using the Advanced LAN Bypass library and related SW APIs, applications running on the host system can access the LAN Bypass MCUs in the system in order to change bypass behavior or to activate and use additional features such as the inte- grated WDT functionality.

  • Page 16: Host Interface

    This allows various schemes for applications controlling the bypass segments. In most cases, a centralized control application or OS is used to manage LAN bypass on the system. In such a scenario, the control plane can still control each bypass segment independently (e.g., force one segment into bypass mode but keep another...

    2.5.1 Standard Watchdog Mechanism In this mode, the WDT in the LAN Bypass MCU is controlled by the host SW via the regular messaging interface. The host SW issues API commands to configure and start, stop, or reset the WDT (see Section 3.7.4 for more details).

  • Page 20: Toggle Pin Mechanism

    2.5.2 Toggle Pin Mechanism In this mode, a dedicated signal ("toggle pin") between the NIC and LAN Bypass MCU is used to strobe the WDT and keep it from timing out. Every signal state change (i.e., each rising or falling edge) will be treated as a WDT strobe.

  • Page 21: Global Watchdog Trigger Mechanism

    Either one single or multiple masters can assert the global WDT trigger signal. Any LAN Bypass MCU can be configured to be a master or slave or to ignore the global WDT trigger signal via dedicated Advanced LAN Bypass SW API commands.

    The Master/Slave Mode LED shows the system's bypass state based on the Mas- ter/Slave Mode LED configuration. 2.6.3 Master/Slave Mode Button The Master/Slave Mode button can be used to directly change the bypass state. It alternatingly triggers the events Button Event 1 and Button Event 2. Advanced LAN Bypass User Manual...

    Duty can be set as an integer between 0 and 100. The value represents the duty cycle as a percentage. Period can be set between 1 and 255 (increment: 100 ms). The LAN Bypass MCU uses the following formula to calculate T (ON time) and T (OFF time).
