Model  830/SB2  -  Processor  feature  codes  and  CCINs 
For  use  by  authorized  service  providers. 
The  processor  cards  in  this  system  can  only  be  attached  to  the  backplane  once.  If  a  processor  card  is 
removed,  it  must  be  replaced  with  a  new  processor  card. 
Perform  the  following: 
1.  Use  control  panel  function  20  to  determine  the  processor  feature  code  (if  it  has  not  already  been 
determined). 
2.  Use  the  table  below  to  determine  the  CCIN  and  location  for  the  processor  cards. 
3.  Use  the  CCIN  in  conjunction  with  the  “Type,  model,  and  part  number  list”  on  page  520  to  obtain  the 
part  numbers  for  the  processors  that  you  will  need  to  replace. 
4.  Refer  to  Models  830/SB2  with  FC  9074  -  System  unit  backplane  (MB1)  and  Models  830/SB2  with  FC
