處理情況：
根據日誌（紅色標記處），判斷CPB出問題。
1.2013-06-02
下午 15:00左右，CPB備件到貨。
2.2013-06-02 晚上 20:30左右，主機停機，停電，進行更換CPB，更換後，加電，發現
Cell 2 仍然LED指示燈不亮。
3.進MP查看報錯信息發現
Cell 2板上 FSB出問題，
如圖所示，判定FSB出問題

4.2013-06-02 晚上 21:30 ,更換CELL板上
FSB固件插在主機 Cell2上。
5.加電，發現 主機 Cell 2指示燈現在正常，進入操作系統，發現
Cell 2上的內存，CPU能夠識別，Cell2顯示正常。如圖：

總結：此次問題，第一次日誌報警是假象，實際是因爲cell板固件FSB出問題引起 （FSB相當於一個電阻，擁有減壓的）。
