错误检查和校正，MICROSET 104988-E03冗余CPU附带启用错误检查和纠正（ECC）功能。启用ECC会导致系统性能稍慢，主要是在通电期间，因为它使用了必须初始化的额外八位。如果在非冗余CPU型号上升级固件以支持冗余，则必须将ECC跳线设置为已启用状态，如升级工具包附带的安装说明所述。有关MICROSET 104988-E03的详细信息，请参阅《MICROSET 104988-E03热备用CPU冗余用户手册》，MICROSET 104988-E03。注意：当检测到单个位ECC错误时，可能会生成多个可恢复内存错误错误。当检测到一个单比特ECC错误时，对提供给微处理器的值进行校正。然而，存储在RAM中的值直到微处理器下次写入该RAM位置时才会被校正。每个CPU都有三个独立的板载串行端口，可通过模块前部的连接器访问。COM1和COM2为外部设备提供串行接口；两者都可以用于固件升级。第三个板载串行端口是一个专用的以太网MICROSET 104988-E03r端口。有关串行端口引脚分配、电气隔离和串行通信的详细信息，请参阅第5章。MICROSET 104988-E03

Error Checking and Correction, MICROSET 104988-E03Redundancy CPUs are shipped with error checking and correction (ECC) enabled. Enabling ECC results in slightly slower system performance, primarily during power-up, because it uses an extra eight bits that must be initialized. If you upgrade the firmware on a non-redundancy CPU model to support redundancy, you must set the ECC jumper to the enabled state as described in the installation instructions provided with the upgrade kit. For details on ECC, refer to the PACSystems Hot Standby CPU Redundancy User Manual,MICROSET 104988-E03. Note: Multiple Recoverable Memory Error faults may be generated when a single-bit ECC error is detected. When a single-bit ECC error is detected, the value presented to the microprocessor is MICROSET 104988-E03corrected. However, the value stored in RAM is not corrected until the next time the microprocessor writes to that RAM location.Each CPU has three independent, on-board serial ports, accessed by connectors on the front of the module. COM1 and COM2 provide serial interfaces to external devices; either can be used for firmware upgrades. The third on-board serial port is a dedicated Ethernet Station Manager port. For serial port pin assignments, electrical isolation and details on serial communications, refer to Chapter 5.MICROSET 104988-E03
