To  replace  the  ServeRAID-8k-l  SAS  Controller  with  a  ServeRAID-8k  SAS  Controller, 
complete  the  following  steps: 
 
1.  Read  the  safety  information  that  begins  on  page  v  and  the  “Installation 
guidelines”  on  page  9. 
 
2.  Turn  off  the  server  and  peripheral  devices  and  disconnect  all  power  cords  and 
external  cables  (see  “Turning  off  the  server”  on  page  39).
 Attention:  In  a  dc  power  environment,  only  trained  service  personnel  other 
than  IBM  service  technicians  are  authorized  to  connect  or  disconnect  power  to 
the  dc  power  supply.  See  the  documentation  that  comes  with  each  dc  power 
supply. 
 
3.  Remove  the  server  cover  (see  “Removing  the  cover”  on  page  11). 
 
4.  Remove  the  riser-card  assembly  and  the  air  baffle  over  the  DIMMs.  See  the 
User’s  Guide  for  more  information. 
 
5.  Locate  the  ServeRAID-8k-l  SAS  controller  on  the  system  board.
 Attention:  To  avoid  breaking  the  retaining  clips  or  damaging  the  connectors, 
handle  the  clips  gently. 
 
6.  Open  the  retaining  clip  on  each  end  of  the  connector. 
 
7.  Lift  the  ServeRAID-8k-l  SAS  controller  out  of  the  connector. 
 
8.  Touch  the  static-protective  package  that  contains  the  new  ServeRAID-8k  SAS 
controller  to  any  unpainted  metal  surface  on  the  server.  Then,  remove  the 
ServeRAID-8k  SAS  controller  from  the  package.

edge  align  correctly  with  the  connector. 
10.  Firmly  press  the  ServeRAID-8k  SAS  controller  straight  down  into  the  connector 
by  applying  pressure  on  both  ends  of  the  controller  simultaneously.  The
