GE HD 1.5T MR系统不能正常启机,TPS不通维修案例

  设备名称:GE MR

  机器型号:EXCITE HD 1.5T

  关 键 词:错误代码2223621、2223849 系统启动超时

  故障描述(信息查看):

  1.机器在扫描期间报错:224862

  The GP is reporting a SGA Power Supply Under Voltage Fault.

  2.之后做TPS不通,重启

  3.系统超时,依次报错:

  2223621

  Internal Software ERROR.Can’t callback on undefined NMRID:SCT

  2218574

  Communications have failed. Please try again.

  2252106

  Diagnostic software error.

  Failed to determine hardware state for AGP board within 2- seconds.

  The board may be busy loading vxWorks or may be hung.

  Also check the serial cable for the board and the serial terminal
server.

  2223849

  AGP/SCP/APS EPROM poewr-up boot failed.Verify that MCP750 boards are
installed and seated properly for APS and AGP.

  故障诊断(分析):

  1.从主机上ping APS板通,ping AGP板不通,ping SCP板通,ping Term Server通;

  2.去设备间发现AGP板上的四个灯都不亮,正常情况下AGP板和APS板上的灯应该同闪烁(如下图);

  3. 随后用笔记本连接Network Switch,并pingAPS板,AGP板,SCP板,Term Server只有AGP板不通;

  4. 对Network Switch上与APS,AGP,SCP相连接的网线依次进行检查正常;

  5. 随后对Term Server断电重启设置并测量电源电压12V均正常;

  6. 最后对MGD柜进行最小化,并对各个板子逐一插入检查,只有当IRF板插入后,AGP板上的灯就会不亮且无论从主机还是Network
Switch上pingAGP板都不通。

  故障解决:

  更换IRF板后,观察AGP板和APS板上的灯同步,且都可以ping通,重启系统正常,TPS通过,扫描正常。
