LXN1604-6 3BHL000986P7000 导轨电源LXN1604-6 3BHL000986P7000是一款导轨电源，属于ABB品牌的产品。它具有可从两个服务器访问的32位邮箱微处理器，并且提供处理器间接口的VMEbus表达邮箱，具有中断的能力。当VMEbus访问微处理器时，可以通过中断处理程序响应任何或所有的信号VMEbus IRQ*行。所有正常过程VMEbus都是相关的中断，可以映射到PCI INTA或SERR中断。
此外，该导轨电源还具有故障自我检测和恢复功能，确保系统的稳定运行。当主处理器发生故障时，备用处理器将自动接管并继续执行任务，从而确保系统的连续性和高可用性。
该导轨电源的底板有两个RJ45以太网端口（CN1、CN2）用于连接到控制网络，以及两个RJ45串行端口（COM3、COM4）。其中一个串行端口（COM3）是带有调制解调器控制信号的RS-232C端口，而另一个端口（COM4）是隔离的，用于连接配置工具。
LXN1604-6 3BHL000986P7000 is a rail power supply and belongs to the ABB brand. It has a 32-bit mailbox microprocessor that can be accessed from two servers and provides a VMEbus interface between processors to express the mailbox, with interrupt capability. When VMEbus accesses the microprocessor, it can respond to any or all signal VMEbus IRQ * lines through an interrupt handler. All normal VMEbus processes are related interrupts that can be mapped to PCI INTA or SERR interrupts.
In addition, the rail power supply also has fault self detection and recovery functions to ensure the stable operation of the system. When the main processor fails, the backup processor will automatically take over and continue to perform tasks, ensuring system continuity and high availability.
The chassis of this rail power supply has two RJ45 Ethernet ports (CN1, CN2) for connecting to the control network, as well as two RJ45 serial ports (COM3, COM4). One of the serial ports (COM3) is an RS-232C port with a modem control signal, while the other port (COM4) is isolated and used to connect configuration tools.
