Safety and Regulatory Information
Important Safety Instructions
Read all caution and safety statements in this document before performing any of the instructions.
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
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 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.
Warnings
IMPORTANT ADDITIONAL INSTALLATION REQUIREMENTS FOR CONNECTION TO SINGLE AC
SOURCE!
Note: 1. These additional installation requirements ONLY apply when 4 PSU’s are connected to a high
voltage line (220V or higher).
Note: 2. These requirements DO NOT apply when PSU’s are connected to low voltage lines (100-
127V and 200V) OR if at least one PSU is connected into a separate AC source (e.g. UPS).
These additional installation requirements are REQUIRED to Avoid Risk of High Leakage Current which may
result in Electric Shock.
1. Systems REQUIRE being installed in a location having equipotential bonding
(such as a telecommunication center, a dedicated computer room or a *RESTRICTED ACCESS
LOCATION).
