Chapter  1.  Introduction 
This  Installation  Guide  contains  instructions  for  setting  up  your  IBM
® 
System  x3650 
Type  7979  server  and  basic  instructions  for  installing  some  optional  devices.  More 
detailed  instructions  for  installing  optional  devices  are  in  the  User’s  Guide  on  the 
IBM  System  x  Documentation  CD,  which  comes  with  the  server.  This  document 
contains  information  about: 
v  Setting  up  and  cabling  the  server 
v  Starting  and  configuring  the  server 
v  Installing  some  optional  devices 
v  Solving  problems 
Attention:  The  information  in  this  document  regarding  installing  and  removing 
power  supplies  and  connecting  and  disconnecting  power  refers  to  ac  power 
supplies  only.  If  the  server  contains  dc  power  supplies,  see  the  documentation  that 
comes  with  the  dc  power  supplies.  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  and  to  install  and  remove  a  dc  power 
supply. 
The  server  has  two  model  styles,  which  are  based  on  the  size  and  number  of  hard 
disk  drive  bays: 
v  The  3.5-inch  models  have  six  3.5-inch  hot-swap  hard  disk  drive  bays.  Install  only 
3.5-inch  drives  in  these  models.  If  you  intend  to  install  a  tape  drive,  the  tape 
drive  will  occupy  two  of  the  six  3.5-inch  drive  bays. 
 
 
v  The  2.5-inch  models  have  eight  2.5-inch  hot-swap  hard  disk  drive  bays  and  one 
3.5-inch  tape  drive  bay.  Install  only  2.5-inch  hard  disk  drives  and  an  optional 
3.5-inch  tape  drive  in  these  models. 
 
 
Throughout  this  documentation,  the  terms  2.5-inch  models  and  3.5-inch  models  are 
used  to  distinguish  between  the  server  styles. 
If  firmware  and  documentation  updates  are  available,  you  can  download  them  from 
the  IBM  Web  site.  The  server  might  have  features  that  are  not  described  in  the 
documentation  that  comes  with  the  server,  and  the  documentation  might  be  updated 
occasionally  to  include  information  about  those  features,  or  technical  updates  might 
be  available  to  provide  additional  information  that  is  not  included  in  the  server 
documentation.  To   check  for  updates,  complete  the  following  steps:
Note:
  Changes  are  made  periodically  to  the  IBM  Web  site.  Procedures  for  locating 
firmware  and  documentation  might  vary  slightly  from  what  is  described  in  this 
document.
