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.
