Safety Information
Important Safety Instructions
Read all caution and safety statements in this document before performing any ofthe
instructions.
Warnings
Heed safety instructions: Before working with the server, whether using this manual
or any other resource as areference, pay close attention to the safety instructions.
Adhere to the assembly instructions in this manual to ensure and maintain
compliance with existing product certifications and approvals. Use only thedescribed,
regulated components specified in this manual. Use of other products /components
will void the UL listing and other regulatory approvals of the product and will most
likely result in non-compliance 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 opening the chassis,
adding, or removing 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 damagedrives,
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 the server when handling parts.
ESD and handling boards: Always handle boards carefully. They can be extremely
sensitive to electrostatic discharge (ESD). Hold boards only by their edges. After
removing aboard from its protective wrapper or from the server, place the board
component side up on agrounded, static free surface. Use aconductive foam pad if
available but not the board wrapper. Do not slide board over anysurface.
Installing or removing jumpers: Ajumper is asmall plastic encased conductor
that slips over two jumper pins. Some jumpers have asmall tab on top that can
be gripped with fingertips or with apair of fine needle nosed pliers. If the jumpers
do not have such atab, take care when using needle nosed pliers to remove or
install ajumper; 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 used to remove ajumper, or the pins on
the board may bend or break.

Safety Measures
WARNING!
Always ask for assistance to move or lift the system.
WARNING!
Only perform troubleshooting as authorized by the product documentation,
or as directed by aservice and support team. Repairs not authorized by
warranty may void the warranty and damage the system.
WARNING!
Always make sure to disconnect the system from the AC electrical source.
Powering down the system DOES NOT ensure there is no electrical activity
in the system.
WARNING!
•Server components and circuit boards are easily damaged by discharges
of static electricity. Working on servers that are connected to apower
supply can be extremely dangerous. Follow the simple guidelines below
to avoid damage to the server or personal injury.
•Always disconnect the server from the power outlet whenever you are
working inside the server case.
•Wear agrounded wrist strap. If none are available, discharge any
personal static electricity by touching the bare metal chassis of the server
case, or the bare metal body of any other grounded device.
•Humid environments tend to have less static electricity than dry
environments.
•Agrounding strap is warranted whenever danger of static electricity
exists.
•Do not touch the components on the chassis unless it is necessary to do
so. Do not flex or stress circuit boards.
•Leave all replacement components inside their static-proof packaging
until you are ready to use them.
