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.
