Removing  the  left-side  cover 
Important:  Before  you  install  optional  hardware,  make  sure  that  the  server  is 
working  correctly.  Start  the  server,  and  make  sure  that  the  operating  system  starts, 
if  an  operating  system  is  installed,  or  that  a  19990305  error  code  is  displayed, 
indicating  that  an  operating  system  was  not  found  but  the  server  is  otherwise 
working  correctly.  If  the  server  is  not  working  correctly,  see  the  Problem 
Determination  and  Service  Guide  for  diagnostic  information.
