计算机组成硬件综合实验箱故障诊断与维护探讨

Discussion on Fault Diagnosis and Maintenance of Computer Hardware Comprehensive Experimental Box

通过对计算机硬件综合实验箱在微程序状态下运行时各指示灯的变化状态,结合微程序代码表及长期的实践经验,总结出一套基于微程序代码表的维护方案和故障处置方法。同时,也举例说明实验过程中的故障处置要点。不但能有效提高设备完好率,保障实验教学的正常开展,还极大减轻硬件维护人员的维护工作量。

According to the change state of each indicator light when the computer hardware comprehensive experimental box runs in microprogram state,combined with microprogram code table and long-term practical experience,a set of maintenance scheme and fault handling method based on microprogram code table are summarized,and at the same time,some examples are given to illustrate the main points of fault handling during the experiment.It can not only effectively improve the equipment intact rate and ensure the normal development of experimental teaching,but also greatly reduce the workload of hardware maintenance staff.
