Troubleshooting  tables 
Use  the  troubleshooting  tables  to  find  solutions  to  problems  that  have  identifiable 
symptoms. 
If  you  cannot  find  the  problem  in  these  tables,  see  the  Problem  Determination  and 
Service  Guide  on  the  IBM  System  x  Documentation  CD  for  information  about 
testing  the  server. 
If  you  have  just  added  new  software  or  a  new  optional  device  and  the  server  is  not 
working,  complete  the  following  steps  before  using  the  troubleshooting  tables: 
1.  Check  the  light  path  diagnostics  LEDs  on  the  operator  information  panel  (see 
“Light  path  diagnostics”  on  page  90). 
2.  Remove  the  software  or  device  that  you  just  added. 
3.  Run  the  diagnostic  tests  to  determine  whether  the  server  is  running  correctly. 
4.  Reinstall  the  new  software  or  new  device.
