2.  If  you  plan  to  configure  the  server  for  RAID  operations  through  the 
ServeRAID-8k  controller,  the  ServeRAID-8s  controller,  the  optional 
ServeRAID-10is  controller,  or  a  combination  of  these  controllers,  you  must 
configure  the  disk  arrays  before  you  install  the  operating  system.  See  the 
ServeRAID
™ 
documentation  on  the  IBM  ServeRAID  Support  CD  for  additional 
information  about  RAID  operation  and  complete  instructions  for  using 
ServeRAID  Manager.
Installing  an  additional  microprocessor 
The  following  notes  describe  the  type  of  microprocessor  that  the  server  supports 
and  other  information  that  you  must  consider  when  you  install  a  microprocessor: 
v  For  a  list  of  supported  optional  devices  for  the  server,  see  http://www.ibm.com/
servers/eserver/serverproven/compat/us/. 
v  See  the  System  x3500  Type  7977  User’s  Guide  on  the  IBM  System  x 
Documentation  CD  for  details  about  how  to  install  a  microprocessor. 
v  The  server  supports  Intel  Xeon  dual-core  or  quad-core  1.6  GHz  or  higher 
microprocessors  in  each  socket.  If  you  are  installing  two  microprocessors,  they 
must  be  the  same  cache  size  and  type,  and  the  same  clock  speed. 
v  Some  models  support  dual-core  processors  and  quad-core  processors.  Do  not 
mix  dual-core  processors  and  quad-core  processors  in  the  same  server.  Install  all 
dual-core  or  all  quad-core  processors  in  the  server. 
v  Read  the  documentation  that  comes  with  the  microprocessor  to  determine 
whether  you  must  update  the  basic  input/output  system  (BIOS)  code  in  the 
server.  To   download  the  most  current  level  of  BIOS  code  for  the  server,  go  to 
http://www.ibm.com/systems/support/. 
v  Obtain  an  SMP-capable  operating  system.  For  a  list  of  supported  operating 
systems,  see  http://www.ibm.com/servers/eserver/serverproven/compat/us/. 
v  You  can  use  the  Configuration/Setup  Utility  program  to  determine  the  specific 
type  of  microprocessor  in  the  server.
To
  install  a  microprocessor,  complete  the  following  steps: 
1.  Read  the  safety  information  that  begins  on  page  vii  and  “Installation  guidelines” 
on  page  7. 
2.  Turn  off  the  server  and  peripheral  devices,  and  disconnect  the  power  cords  and 
all  external  cables. 
3.  Lay  the  server  on  its  side;  then,  remove  the  left-side  cover. 
 
Attention:  When  you  handle  static-sensitive  devices,  take  precautions  to 
avoid  damage  from  static  electricity.  For  details  about  handling  these  devices, 
see  “Handling  static-sensitive  devices”  on  page  9. 
4.  Remove  the  microprocessor  air  duct  from  the  fan  structure.  Squeeze  the  two 
tabs  on  the  top  of  the  air  duct  together  and  lift  the  air  duct  out  of  the  server. 
5.  Remove  the  microprocessor  baffle  and  the  protective  film  from  the  second 
microprocessor  socket.
