Safety Information
Warnings
Heed safety instructions: 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.
System power on/off: The power button DOES NOT turn off the system AC power. To
remove power from the 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.
