Preface 
Safety Information 
 WARNING 
Before working with your server product, whether you are using this guide or any other 
resource as a reference, pay close attention to the safety instructions. You must adhere to the 
assembly instructions in this guide to ensure and maintain compliance with existing product 
certifications and approvals.  Use only the described, regulated components specified in this 
guide.  Use of other products / components will void the UL listing and other regulatory 
approvals of the product and will most likely result in noncompliance with product 
regulations in the region(s) in which the product is sold. 
 
Warnings
 
System power on/off:  The power button DOES NOT turn off the system 
AC power.  To remove power from system, you must unplug the AC power 
cord from the wall outlet.  Make sure the AC power cord is unplugged before 
you open the chassis, add, or remove any components. 
Hazardous conditions, devices and cables:  Hazardous electrical 
conditions may be present on power, telephone, and communication cables.  
Turn off the server and disconnect the power cord, telecommunications 
systems, networks, and modems attached to the server before opening it.  
Otherwise, personal injury or equipment damage can result. 
Electrostatic discharge (ESD) and ESD protection:  ESD can 
damage disk drives, boards, and other parts.  We recommend that you 
perform all procedures in this chapter only at an ESD workstation.  If one is 
not available, provide some ESD protection by wearing an antistatic wrist 
strap attached to chassis ground
⎯any unpainted metal surface⎯on your 
server when handling parts. 
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 pins on the board.
