ESD and handling boards:
  Always handle boards carefully.  They can 
be extremely sensitive to ESD.  Hold boards only by their edges.  After 
removing a board from its protective wrapper or from the server, place the 
board component side up on a grounded, static free surface.  Use a 
conductive foam pad if available but not the board wrapper.  Do not slide 
board over any surface. 
Installing or removing jumpers:
  A jumper is a small plastic encased 
conductor that slips over two jumper pins.  Some jumpers have a small tab on 
top that you can grip with your fingertips or with a pair of fine needle nosed 
pliers.  If your jumpers do not have such a tab, take care when using needle 
nosed pliers to remove or install a jumper; grip the narrow sides of the 
jumper with the pliers, never the wide sides.  Gripping the wide sides can 
damage the contacts inside the jumper, causing intermittent problems with 
the function controlled by that jumper.  Take care to grip with, but not 
squeeze, the pliers or other tool you use to remove a jumper, or you may 
bend or break the stake pins on the board.

The power supply in this product contains no user-serviceable parts.  There may be more 
than one supply in this product.  Refer servicing only to qualified personnel. 
 
 
Do not attempt to modify or use the supplied AC power cord if it is not the exact type 
required.  A product with more than one power supply will have a separate AC power cord 
for each supply. 
  
 
 
The power button on the system does not turn off system AC power.  To remove AC power 
from the system, you must unplug each AC power cord from the wall outlet or power supply. 
The power cord(s) is considered the disconnect device to the main (AC) power.  The socket 
outlet that the system plugs into shall be installed near the equipment and shall be easily 
accessible. 
  
 
SAFETY STEPS:  Whenever you remove the chassis covers to access the inside of the 
system, follow these steps: 
1.  Turn off all peripheral devices connected to the system. 
2.  Turn off the system by pressing the power button. 
3.  Unplug all AC power cords from the system or from wall outlets. 
4.  Label and disconnect all cables connected to I/O connectors or ports on the back of the 
system.
