原机的主板断电后加电报错为：1、System Board PF ault Fail Safe:Voltage sensor for System Board,state asserted was asserted.

2、VR PG：Voltage sensor,state asserted was asserted.

换上新的主板后报错代码为（新主板是经过测试的完好的主板）：

E1000  Failsafe voltage error.Contact support.

E1219  Disk Backplane power failur.Check BP power cable.

怀疑可能存才除主板外其他故障，请各位大神帮忙想想办法，拜谢.
