8.  Connect  one  end  of  the  tape  drive  USB  cable  to  the  USB  connector  on  the 
system  board;  then,  route  the  USB  cable  through  the  cable  holders  on  the 
inside  of  the  server  and  connect  the  opposite  end  of  the  cable  to  the  USB  tape 
drive. 
 
9.  Reinstall  the  front  fan  cage  assembly. 
10.  Replace  the  left-side  cover  and  bezel;  then,  lock  the  side  cover  and  bezel. 
11.  Reconnect  the  external  cables  and  power  cords. 
If  you  have  other  optional  devices  to  install  or  remove,  do  so  now.  Otherwise,  go  to 
“Completing  the  installation”  on  page  46. 
Installing  a  hot-swap  hard  disk  drive 
The  following  notes  describe  the  types  of  hard  disk  drives  that  the  server  supports 
and  other  information  that  you  must  consider  when  you  install  a  hard  disk  drive: 
v  Depending  on  the  model,  the  server  supports  up  to  eight  1–inch  (26  mm)  slim 
high,  3.5-inch  SAS/SATA  hot-swap  hard  disk  drives  or  up  to  twelve  1-inch  (26 
mm)  slim-high,  2.5-inch,  SAS/SATA  hot-swap  hard  disk  drives  in  the  standard 
hot-swap  bays. 
v  The  hot-swap  bays  are  arranged  vertically  in  the  standard  hard  disk  drive  cage; 
the  bay  numbers  are  0  through  7  (from  top  to  bottom)  on  models  with  eight  hard 
disk  drives  and  0  through  11  (from  top  to  bottom)  on  models  with  12  hard  disks. 
v  For  a  list  of  supported  optional  devices  for  the  server,  see  http://www.ibm.com/
servers/eserver/serverproven/compat/us/.
 
v  Inspect  the  drive  tray  for  signs  of  damage. 
v  Make  sure  that  the  drive  is  correctly  installed  in  the  tray. 
v  See  the  documentation  for  the  ServeRAID-8k  and  ServeRAID-8s  SAS  Controller 
for  instructions  for  installing  a  hard  disk  drive. 
v  All  hot-swap  drives  in  the  server  must  have  the  same  throughput  speed  rating; 
using  drives  with  different  speed  ratings  might  cause  all  drives  to  operate  at  the 
throughput  of  the  slowest  drive. 
v  To   minimize  the  possibility  of  damage  to  the  hard  disk  drives  when  you  are 
installing  them  in  a  rack  configuration,  install  the  server  in  the  rack  before  you 
install  the  hard  disk  drives. 
v  You  do  not  have  to  turn  off  the  server  to  install  hot-swap  drives  in  the  hot-swap 
drive  bays.  However,  you  must  turn  off  the  server  when  you  perform  any  steps 
that  involve  installing  or  removing  cables. 
v  The  drive  ID  for  each  hot-swap  hard  disk  drive  is  printed  on  the  bezel.
To
  remove  a  hot-swap  hard  disk  drive,  complete  the  following  steps.
