Heed safety instructions: Before working with your workstation 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 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 workstation and disconnect the power
cord, telecommunications systems, networks, and modems attached to the workstation 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 workstation 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 workstation, 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.
